Singapore International Commercial Court — Originating Application No 15
of 2024 and Summons No 61 of 2024
Philip Jeyaretnam J, Anselmo Reyes IJ and Peter Meier-Beck IJ
16, 17 January, 28 February 2025
Judgment reserved.
20 March 2025
Philip Jeyaretnam J (delivering the judgment of the court):
1 This is an application by the claimant, the Republic of Korea (“ROK”),
to set aside the final award dated 11 April 2024 (the “Award”) issued by the
arbitral tribunal (the “Tribunal”) in the arbitration in PCA Case No. 2018-55
(the “Arbitration”) in favour of the defendants, Mason Capital LP and Mason
Management LLC (collectively, “Mason”). The Arbitration had been
commenced by Mason invoking the Free Trade Agreement between ROK and
the US (the “FTA”).1
2 Mason is a US investment fund which owned a 2.18% stake in Samsung
C&T Corporation (“SC&T”). ROK’s National Pension Service (“NPS”) was
[Page 2]
SC&T’s largest shareholder, with an 11.21% stake. SC&T and Cheil Industries,
Inc (“Cheil”), both Korean companies, were part of the Samsung group of
companies (the “Samsung Group”).
3 On 26 May 2015, SC&T and Cheil announced plans to merge (the
“Merger”), with a proposed merger ratio of 1 Cheil share to approximately
0.35 SC&T shares (the “Merger Ratio”). To Mason and certain other SC&T
shareholders, the Merger Ratio overvalued Cheil and undervalued SC&T, and
they opposed the Merger.2 Nevertheless, 69.53% of SC&T shareholders,
including NPS, eventually voted in favour of the Merger on 17 July 2015. This
crossed the two-thirds threshold required for approval. The value of SC&T
shares subsequently declined, resulting in losses to Mason.
4 On 7 June 2018, Mason commenced the Arbitration, seated in
Singapore, against ROK under the FTA. Mason claimed that Korean
government officials improperly and illegally manipulated NPS’s exercise of its
vote to approve the merger, in violation of the minimum standard of treatment
and national treatment standard under the FTA, thereby causing damage to
Mason. ROK denied these claims.3
5 In so commencing the Arbitration, Mason would in legal analysis be
described as purporting to accept the standing unilateral offer to arbitrate made
by ROK by its entry into the FTA. Under this analysis, such acceptance would
form the agreement to arbitrate the dispute, and so found the jurisdiction of the
tribunal to make an award on the issues submitted to it. It is axiomatic that an
acceptance must match the offer made. The acceptor must fall within the class
2 Defendants’ Written Submissions dated 20 December 2024 (“DWS”) at para 15. ↩
3 Award at para 5. ↩
[Page 3]
of persons to whom the offer was made. The dispute too must be one that falls
within the scope of the offer to arbitrate. Where the acceptance does not match
the offer, no agreement to arbitrate is formed and the tribunal will lack
jurisdiction.
6 Mason’s claims concerned alleged breaches of provisions in Chapter 11
of the FTA. Article 11.1.1 of the FTA, which is contained within Section A of
Chapter 11, states:
ARTICLE 11.1: SCOPE AND COVERAGE
1. This Chapter applies to measures adopted or maintained by
a Party relating to:(a) investors of the other Party;
(b) covered investments; and
(c) with respect to Articles 11.8 and 11.10, all
investments in the territory of the Party.[emphasis added]
7 Article 1.4 of the FTA defines “measures” to include “any law,
regulation, procedure, requirement or practice”.
8 Article 11.1.3 of the FTA stipulates that:
3. For purposes of this Chapter, measures adopted or
maintained by a Party means measures adopted or
maintained by:(a) central, regional, or local governments and
authorities; and
[Page 4]
(b) non-governmental bodies in the exercise of powers
delegated by central, regional, or local governments or
authorities.[emphasis in original]
9 Articles 11.16 and 11.17 of the FTA provide for the submission of
claims to arbitration in the following terms:
ARTICLE 11.16: SUBMISSION OF A CLAIM TO ARBITRATION
1. In the event that a disputing party considers that an
investment dispute cannot be settled by consultation and
negotiation:(a) the claimant, on its own behalf, may submit to
arbitration under this Section a claim(i) that the respondent has breached
(A) an obligation under Section A,
(B) an investment authorization, or
(C) an investment agreement;
and
(ii) that the claimant has incurred loss or damage
by reason of, or arising out of, that breach; and(b) the claimant, on behalf of an enterprise of the
respondent that is a juridical person that the claimant
owns or controls directly or indirectly, may submit to
arbitration under this Section a claim(i) that the respondent has breached
(A) an obligation under Section A,
(B) an investment authorization, or
(C) an investment agreement;
and
(ii) that the enterprise has incurred loss or
damage by reason of, or arising out of, that
breach,provided that a claimant may submit pursuant to
subparagraph (a)(i)(C) or (b)(i)(C) a claim for breach of an
investment agreement only if the subject matter of the
[Page 5]
claim and the claimed damages directly relate to the
covered investment that was established or acquired, or
sought to be established or acquired, in reliance on the
relevant investment agreement....
ARTICLE 11.17: CONSENT OF EACH PARTY TO ARBITRATION
1. Each Party consents to the submission of a claim to
arbitration under this Section in accordance with this
Agreement....
[emphasis added]
10 Article 11.28 of the FTA defines “investment” as follows:
investment means every asset that an investor owns or
controls, directly or indirectly, that has the characteristics of an
investment, including such characteristics as the commitment
of capital or other resources, the expectation of gain or profit,
or the assumption of risk. Forms that an investment may take
include:(a) an enterprise;
(b) shares, stock, and other forms of equity participation
in an enterprise;...
11 On 11 April 2024, the Tribunal issued the Award, finding that ROK had
breached the FTA in relation to Mason’s investments, and ordering ROK to pay
Mason damages of approximately US$32m.4
12 ROK now seeks to set aside the Award on five independent grounds:5

13 In the course of the Arbitration, the Tribunal rejected the Investor
Objection in Mason Capital LP and another v Republic of Korea, PCA Case
No. 2018-55, Decision on Respondent’s Preliminary Objections (22 December
2019) (the “Decision on Preliminary Objections”).6 The Tribunal also rejected

[Page 7]
the Measures Objection, the Relating To Objection and the Standing Objection
in its final Award.7
14 ROK characterises its objections (other than the Natural Justice
Objection) as jurisdictional in nature.8 As a threshold issue, Mason disputes that
these objections are jurisdictional. Additionally, Mason argues that the Investor
Objection is time-barred.9
15 Four broad issues arise for our determination:

[Page 8]
17 ROK relies principally on Art 34(2)(a)(iii) of the UNCITRAL Model
Law on International Commercial Arbitration (“MAL”), which provides that an
arbitral award may be set aside where “the award deals with a dispute not
contemplated by or not falling within the terms of the submission to arbitration,
or contains decisions on matters beyond the scope of the submission to
arbitration”.
18 In the alternative, ROK relies on Art 34(2)(a)(i) of the MAL, which
provides that an arbitral award may be set aside where “the [arbitration
agreement] is not valid under the law to which the parties have subjected it or,
failing any indication thereon, under the law of this State”.
19 It is trite that “[c]onsent serves as the touchstone for whether an
objection is jurisdictional because arbitration is a consensual dispute resolution
process: jurisdiction must be founded on party consent”: BBA and others v BAZ
and another appeal [2020] 2 SLR 453 at [78]. In the context of investment
disputes commenced against States, the starting point is that States are sovereign
and not bound to submit to the jurisdiction of any court or tribunal without
consent. States are therefore free to circumscribe their offer to arbitrate in any
way – subject only to the other State party’s agreement: Tulip Real Estate and
Development Netherlands BV v Republic of Turkey, ICSID Case No.
ARB/11/28, Decision on Bifurcated Jurisdictional Issue (5 March 2013) at
[135]; and Final Award (10 March 2014) at [223]. Accordingly, while the
protean or fact-sensitive nature of an issue could factor into whether the
contracting parties expected it to be jurisdictional, a State party’s offer to
arbitrate may well have expressly contemplated such questions as being
jurisdictional.
[Page 9]
20 Under an investment treaty, the State may choose to make a standing
and unilateral offer to arbitrate. By doing so, the State binds itself to arbitrate a
claim that is brought under and in accordance with those terms. What those
terms are will be found in the investment treaty: Swissbourgh Diamond Mines
(Pty) Ltd and others v Kingdom of Lesotho [2019] 1 SLR 263 (“Swissbourgh”)
at [75].
21 The court’s task in determining the scope of a State’s offer to arbitrate
is thus one of construction of the treaty. One commonly recurring question of
interpretation is whether a fact must be proved for the tribunal to have
jurisdiction over the dispute or whether it need only be alleged or asserted, with
its proof then being within the merits which the tribunal has jurisdiction to
determine. In either case, the court undertakes its own review of a tribunal’s
jurisdiction, without deference to the tribunal’s own legal rulings or factual
findings concerning its own jurisdiction. This is the standard known as de novo
review: Sanum Investments Ltd v Government of the Lao People’s Democratic
Republic [2016] 5 SLR 536 at [41].
22 In interpreting the scope of the offer to arbitrate, the court should also
have regard to the principles of treaty interpretation encapsulated in the Vienna
Convention on the Law of Treaties (23 May 1969) 1155 UNTS 331 (entered
into force 27 January 1980) (the “VCLT”), which stipulate:
Article 31: General rule of interpretation
1. A treaty shall be interpreted in good faith in accordance with
the ordinary meaning to be given to the terms of the treaty in
their context and in the light of its object and purpose.2. The context for the purpose of the interpretation of a treaty
shall comprise, in addition to the text, including its preamble
and annexes:
[Page 10]
(a) any agreement relating to the treaty which was made
between all the parties in connection with the
conclusion of the treaty;(b) any instrument which was made by one or more
parties in connection with the conclusion of the treaty
and accepted by the other parties as an instrument
related to the treaty.3. There shall be taken into account, together with the context:
(a) any subsequent agreement between the parties
regarding the interpretation of the treaty or the
application of its provisions;(b) any subsequent practice in the application of the
treaty which establishes the agreement of the parties
regarding its interpretation;(c) any relevant rules of international law applicable in
the relations between the parties.4. A special meaning shall be given to a term if it is established
that the parties so intended.Article 32: Supplementary means of interpretation
Recourse may be had to supplementary means of
interpretation, including the preparatory work of the treaty and
the circumstances of its conclusion, in order to confirm the
meaning resulting from the application of article 31, or to
determine the meaning when the interpretation according to
article 31:(a) leaves the meaning ambiguous or obscure; or
(b) leads to a result which is manifestly absurd or
unreasonable.
23 The VCLT thus organises the task into two stages. First under Art 31,
the court considers the ordinary meaning of the treaty’s terms in their context
and in the light of the treaty’s object and purpose. For this first step, the context
is limited to the text of the treaty itself, including its preamble and annexes.
Further, account is to be taken of three additional matters, namely any
subsequent agreement between the parties concerning the treaty’s interpretation
or application of its provisions, any subsequent practice of the parties that
establishes the agreement of the parties concerning the treaty’s interpretation,
[Page 11]
and any relevant rules of international law applicable in the relations between
the parties. Last, at this first step a special (ie, non-ordinary) meaning may be
given to a term if it is established that that was the parties’ intention. At the
second stage under Art 32, the meaning determined under Art 31 may be
confirmed by reference to supplementary means of interpretation including the
preparatory work of the treaty and the circumstances of its conclusion. If,
however, the meaning determined under Art 31 is ambiguous or obscure, or
leads to a manifestly absurd or unreasonable result, then reference may be made
to such supplementary means of interpretation to arrive at the true meaning of
the term.
24 This general approach to the interpretation of treaties has been
recognised as customary international law and applies equally to the
jurisdictional provisions in investment treaties. There is no question of applying
either a liberal or restrictive interpretation: see Swissbourgh at [61]–[63].
25 ROK’s analysis begins with ROK’s offer to arbitrate as set out in
Arts 11.16 and 11.17 of the FTA (quoted above at [9]). Pursuant to these
provisions, the claimant may submit to arbitration a claim that the respondent
has breached an obligation under Section A of Chapter 11. Each Party also
consents to submit to arbitration “in accordance with this Agreement”. Thus,
ROK reasons, ROK’s offer to arbitrate is circumscribed by Art 11.1.1 of the
[Page 12]
FTA (quoted above at [6]), which provides that Chapter 11 of the FTA applies
only to “measures adopted or maintained” by a Party “relating to” investors of
the other Party and covered investments. The Tribunal therefore has no
jurisdiction to determine disputes which do not satisfy either of these threshold
requirements.10
26 ROK also relies on a diplomatic note dated 28 October 2024 issued by
the US Embassy (the “US Diplomatic Note”), in response to the judgment in
Republic of Korea v Elliott Associates, LP [2024] EWHC 2037 (Comm)
(“Elliott”). The US Diplomatic Note confirmed the US’s interpretation of
Art 11.1 of the FTA that the “measures” and “relating to” requirements are
jurisdictional in nature.11 ROK responded to the US Diplomatic Note on
15 November 2024 (the “ROK’s Reply Diplomatic Note”), confirming it agreed
with the US’s interpretation.12 ROK’s application to adduce evidence
encompassing the US Diplomatic Note and ROK’s Reply Diplomatic Note is
the subject of SIC/SUM 61/2024. ROK submits that this exchange of notes
constitutes a subsequent agreement regarding the interpretation and application
of the FTA within the meaning of Art 31(3)(a) of the VCLT, which must be
regarded as decisive.13
27 While ROK accepts that its objections to jurisdiction, in particular, the
Relating To Objection, may involve consideration of facts that overlap with the
merits of the dispute, ROK ultimately submits that there is no reason why a
10 CWS at paras 39–42. ↩
11 CWS at para 43. ↩
12 CWS at para 44. ↩
13 CWS at para 45. ↩
[Page 13]
jurisdictional objection cannot require consideration of such facts.14 It is the
court’s mandate to review the Tribunal’s findings of fact de novo where such
facts are necessary to establish the Tribunal’s jurisdiction, even if this overlaps
with the merits of the dispute.15
28 As summarised at [33] below, Mason contends that the Measures
Objection and Relating To Objection are not matters for a supervisory court’s
review because it is unclear how (if at all) the non-disputing party to the FTA
(ie, the US) could participate in the proceedings before such a supervisory court.
This compares unfavourably with the position in an arbitration where the non-
disputing party may make submissions on matters of treaty interpretation (see
Art 11.20.4 of the FTA).16 In response, ROK argues that this does not fetter the
court’s supervisory jurisdiction. Such logic would absurdly imply that the court
can never adjudicate any dispute concerning the interpretation of a treaty unless
all affected parties to the treaty are able to participate in the proceedings. The
Court of Appeal’s exercise in treaty interpretation in Swissbourgh demonstrates
otherwise.17
29 Mason contends that the Measures Objection and Relating To Objection
are impermissible attacks on the merits of the Award, and not true jurisdictional
objections.18 Pursuant to Art 11.16.1(a) of the FTA, an investment dispute falls

[Page 14]
within the scope of the consent to arbitrate so long as the claimant alleges: (a) a
breach of an obligation under Section A; and (b) that this has resulted in loss to
it.19 The phrase “in accordance with this Agreement” in Art 11.17.1 refers to
provisions that expressly circumscribe ROK’s consent to arbitrate, such as Art
11.18 (bearing the heading “Conditions and Limitations on Consent of Each
Party”). It does not incorporate Art 11.1.1 as a limitation on ROK’s consent to
arbitrate.20
30 Mason argues that if ROK’s objections were jurisdictional, an investor
would need to prove that the host state had adopted or maintained measures
relating to the investor or its investment. This would involve factually intensive
inquiries that overlap significantly with the merits. It would be anomalous that
such factual matters would not be open to curial review in relation to the merits,
but could be considered de novo in relation to jurisdiction.21
31 Mason finds support for its position in the decision of Foxton J in Elliott,
which arose out of the same factual circumstances as the present case. That case
involved Elliott Associates, LP (“Elliott”), another US investment fund that, like
Mason, held a stake in SC&T at the material time. Elliott commenced a separate
arbitration seated in the UK in respect of the same acts of ROK’s officials
impugned by Mason. The tribunal issued an award in favour of Elliott under the
FTA, and ROK sought to set aside the award in the UK based on the same
“measures” and “relating to” objections it now raises before this court.

[Page 15]
32 Foxton J found that the “measures” and “relating to” requirements in
Art 11.1.1 of the FTA were not jurisdictional in nature. In arriving at this
conclusion, Foxton J considered, among other things, that the issues raised
would engage questions closely connected with the merits of Elliott’s
complaints: Elliott at [50]–[52] and [69(vi)]. Mason submits that Foxton J’s
reasoning is persuasive in the present case, given that challenges based on a
tribunal’s alleged lack of substantive jurisdiction under s 67 of the UK
Arbitration Act 1996 (“UK AA”) entail consideration of the same issues that
arise in challenges to an award under Arts 34(2)(a)(i) and 34(2)(a)(iii) of the
MAL.22
33 Mason further argues that to the extent the Measures Objection and
Relating To Objection involve issues of treaty interpretation, they are not
matters for curial review as there is no mechanism for the US, the non-disputing
state, to participate in proceedings before the curial court. This contrasts with
Art 11.20.4 of the FTA, which permits a non-disputing party to the FTA to make
submissions on matters of treaty interpretation to the tribunal in an arbitration.23
34 Concerning the exchange of diplomatic notes between the US and ROK,
Mason submits that the critical date doctrine is engaged. Since the diplomatic
notes were exchanged long after the critical date of 13 September 2018, the date
when Mason commenced arbitration, the diplomatic notes should be regarded
as self-serving and intended to rescue ROK’s preferred interpretation of Art
11.1.1 of the FTA after the judgment in Elliott was issued. Little if any weight
should be put on them.24 Mason also notes that the diplomatic notes were not
22 DWS at paras 52–53. ↩
23 DWS at paras 56–57. ↩
24 DWS at para 59. ↩
[Page 16]
issued under the procedural mechanism for contracting States to obtain
interpretations of the FTA’s terms provided by Art 22.2.3(d).25
35 Chapter 11 of the FTA is divided into Section A (titled Investment),
Section B (titled Investor-State Dispute Settlement) and Section C (titled
Definitions). Within Section B, the provision for submission of claims to
arbitration is Art 11.16. It is the natural first port of call when considering the
terms of the offer to arbitrate made by the parties to the FTA to investors of the
other party. Art 11.16.1 entitles a claimant to submit to arbitration a claim that
the respondent has breached an obligation under Section A (which includes the
obligations of national treatment, most-favoured nation treatment, minimum
standard treatment and non-expropriation except in accordance with the treaty)
whereby the claimant has incurred loss or damage. The word “claimant” is
defined in Art 11.28 as “an investor of a Party that is a party to an investment
dispute with the other Party”. Thus, the scope of each party’s offer to arbitrate
is addressed only to investors of the other party, and only concerning disputes
about their investments. The word “investment” is also defined in Art 11.28.
Only such a claimant may submit a claim to arbitration under the FTA. Indeed,
it was common ground that Art 11.16 establishes these two jurisdictional
requirements, namely that the claimant be an investor who has an investment.
36 The words that follow the word “claim” in Arts 11.16.1(a) and
11.16.1(b) respectively are naturally read only as reflecting what needs to be
claimed by the claimant. In the context of the claim under review in these
proceedings, it merely had to be properly characterised as a claim for the breach
[Page 17]
of a Section A obligation and resulting loss. Other claims could not be submitted
to arbitration under the FTA. The allegation of facts that amount to such breach
and loss is sufficient for the purpose of a valid submission to arbitration.
Whether there has in fact been a breach of a Section A obligation and whether
that breach has caused loss to the claimant are both matters that do not impinge
on the parties’ consent to arbitrate. Such matters fall within the exclusive
jurisdiction of the tribunal. To be clear, whether the facts as alleged by the
claimant establish a claim for a breach of a Section A obligation and resulting
loss remains a jurisdictional question, one determined by a proper construction
of the treaty.
37 Art 11.16 makes no mention of “measures adopted or maintained by a
Party relating to” the investments of the investor. If Art 11.16 is read as the sole
article governing the submission of claims to arbitration, then whether there
were “measures adopted or maintained” or whether such measures were ones
“relating to” the investor’s investments would not be questions going to the
jurisdiction of the tribunal.
38 At this point however ROK prays in aid Art 11.1. Titled Scope and
Coverage it opens Section A. However, while situated in Section A, it limits the
application of Chapter 11 (not just Section A) to measures adopted or
maintained by a Party relating to covered investments of investors of the other
Party.
39 Mason contends that Art 11.1 should be read as qualifying the actions
of the State that are subject to the substantive obligations set out in Section A
and hence would fall within the tribunal’s determination of the merits of
whether there has been a breach of a Section A obligation.
[Page 18]
40 ROK by contrast contends that it adds a further jurisdictional
requirement to those in Art 11.16, namely that there must have been a measure
adopted or maintained by the respondent relating to the investment of the
claimant.
41 In our view, the ordinary meaning of Chapter 11 and in particular
Arts 11.1 and 11.16, determined in the contextual and purposive manner
mandated by Art 31 of the VCLT, is that the statement in Art 11.1 that the
chapter applies to “measures ... relating to” investors of the other party does not
operate as a jurisdictional requirement or as a limitation to each party’s standing
unilateral offer to arbitrate disputes under Chapter 11, made to investors of the
other party. There are two principal reasons for our conclusion. These reasons
concern first the function the respective articles play and second the
arrangement of similar articles in the context of the treaty as a whole.
42 First, there is the function each article plays within Chapter 11.
Article 11.16 on its face operates as a self-contained gateway for the submission
of all claims under the chapter to arbitration. This point has two aspects to it.
The first is that Art 11.16 is fully workable on its own. There is no necessity
arising whether from logic or workability to treat apparent limitations on the
scope of each party’s substantive obligations (and thus corresponding
limitations on the scope of the investor’s protections) to be found in other
articles as additional jurisdictional requirements. The second point is that
Art 11.16 is the gateway for the submission of all claims under Chapter 11 to
arbitration. Such claims include claims in relation to breach of Section A
obligations but also extend to two other types of claims, namely those for breach
of an investment authorization and those for breach of an investment agreement.
Because Art 11.16 functions as a gateway for three types of claims, one would
expect all jurisdictional limitations to be set out in it, especially where such
[Page 19]
limitations are specific to only one of the types of claims. Fulfilling and
reinforcing this expectation, Art 11.16.1 contains in the proviso a limitation that
a claim for breach of an investment agreement may be submitted “only if the
subject matter of the claim and the claimed damages directly relate to the
covered investment that was established or acquired ... in reliance on the
relevant investment agreement” (quoted at [9] above).
43 Turning to the function of Art 11.1, on its face it describes the contents
of the chapter and thus differentiates it from other chapters. Its placement within
Section A supports the reading that it relates to the scope of the obligations set
out in that section.
44 Second, in our view, the function of Art 11.1 identified above accords
with the context of the rest of the treaty, where some other chapters similarly
start with either “Scope” or “Scope and Coverage” articles. An instructive
example is Chapter 8 which concerns sanitary and phytosanitary measures.
Article 8.1 sets out the measures to which the chapter applies but by Art 8.4
there is specifically no recourse to dispute settlement. Thus, a similarly worded
article to Art 11.1 plays in Chapter 8 the function of merely describing that
chapter without playing any role in relation to dispute settlement (because there
is no recourse to dispute settlement). Contrary to ROK’s submission that Art
11.1 also imposes jurisdictional requirements for the submission of claims under
Art 11.16, when an article has on a contextual reading a particular function
within the arrangement of the treaty as whole, this weighs against imputing a
dual or secondary function to that article.
45 We would add that we do not consider that much weight should be given
to the contention that an issue which is fact-sensitive is less likely to be
jurisdictional in nature. Logically, it should be presumed that parties who have
[Page 20]
chosen arbitration as their method of dispute resolution will ordinarily structure
how the arbitral process works to minimise the overlap between jurisdiction and
the merits. This is because any points of overlap would raise the possible
duplication of time and costs entailed in a de novo review by the supervisory
court. However, this argument from presumed intention must yield to the text
of the treaty interpreted in accordance with Arts 31 and 32 of the VCLT if the
text shows otherwise.
46 Indeed, this accords with Foxton J’s statement of principle at [37(iv)] of
Elliott, which Mr Gearing adopted:
Where an issue involves the application of protean legal
concepts in a highly fact sensitive context, it may be more
difficult in the absence of express language in the offer to
arbitrate to establish that the issue is jurisdictional in nature.
However, if that is the effect of the language used in the treaty
when interpreted in accordance with VCLT principles, the
complexity or sensitivity of the task is neither here nor there.[emphasis added]
Mr Gearing acknowledged that this formulation puts the emphasis on the
interpretation of the relevant treaty.26 The fact that a question is protean does not
necessarily detract from its jurisdictional nature.
47 In this connection, there is a distinction between arbitration in a
commercial context and in an investor-state context. If a commercial party’s
dispute does not fall within the arbitration clause, it has recourse to a national
court. This reduces the incentive for commercial parties to impose fact-sensitive
subject-matter restrictions on a tribunal’s jurisdiction, as alternative forums
would remain available to litigate all other forms of disputes. In contrast, if an
26 17 January 2025 Transcript at p 23, lines 14–18. ↩
[Page 21]
investor’s dispute is not of a type that the State has offered to arbitrate, then the
investor has no equivalent recourse elsewhere. This is a function of state
sovereignty: states are at liberty to (and often) impose subject-matter restrictions
on a tribunal’s jurisdiction because the point is to restrict the types of claims
that can be brought against it in whatever forum. As a result, fact-sensitive
jurisdictional inquiries may be more justifiable in investor-state contexts.
48 Last under this section, we turn to the diplomatic notes. Even though we
allow ROK’s application to adduce them as evidence, we hold that they do not
amount to an agreement concerning the interpretation of the FTA within the
meaning of Art 31(3)(a) of the VCLT because the FTA itself sets out the
mechanism for issuing interpretations of the FTA, namely by the Joint
Committee established under Art 22.2 of the FTA. The diplomatic notes are not
the product of this mechanism. For the same reason, we would also not consider
them to constitute a practice in the application of the FTA that establishes the
agreement of the parties regarding its interpretation within the meaning of Art
31(3)(b) of the VCLT. Their status taken at its highest is merely to reflect the
opinions of the governments of the parties to the FTA, although even for this it
is perhaps significant that the US Diplomatic Note was issued by the US
Embassy in Seoul. In so far as they reflect the contracting States’ opinions
concerning interpretation of the FTA, we have considered them in relation to
the interpretation of the FTA. We have done so notwithstanding that they were
issued long after the critical date. However, we are not persuaded by them. In
our view, the meaning of the text of the FTA, interpreted in accordance with
Art 31 of the VCLT, is as we have articulated it at [41] above.
49 We conclude that the Measures Objection and Relating To Objection are
not jurisdictional in the sense alleged by ROK. On a proper construction of the
FTA, our role is not to make findings of fact de novo to determine whether there
[Page 22]
were “measures adopted or maintained” by ROK “relating to” Mason or their
investment. However, we do have to consider whether the facts as alleged by
Mason are properly characterised as such measures so as to establish a claim
under the FTA. This is the task we now turn to. ROK has asked that we do so
on the basis of the evidence that was before the Tribunal and which was part of
the record that has been exhibited in these proceedings.27 Mason has agreed to
our taking this approach.28 Indeed, in general the primary facts are not in dispute,
and the arguments before us essentially concern their characterisation.
50 Parties agree that the measures in question comprise the following
(collectively, the “Impugned Acts”):29
51 The question is whether, on a proper construction, these Impugned Acts
fall within the scope of “measures adopted or maintained” by ROK.

[Page 23]
52 ROK’s position is that “measures adopted or maintained” refers to acts
that result from the formal exercise of the State’s legislative or administrative
rule-making or enforcement authority.30 Even if the phrase were construed
broadly to include acts that are not formal, it must at least refer to ways in which
the State exercises authority in its jurisdiction, consistently with the State’s laws
and the scope and limits of the authority granted to the relevant official by the
State.31 On either interpretation, illegal, illicit and unsanctioned actions cannot
fall within the scope of Art 11.1.1 of the FTA.32
53 ROK submits that the examples of “measures” listed in Art 1.4 of the
FTA refer to actions or decisions by the State that emerge from formal, structured processes.33 Even the term “practice”, ROK submits, requires a
degree of formality, consistency and regularity in conduct.34 ROK finds support
for this in the terms “adopted”, which it says connotes formal approval or
acceptance, and “maintained”, which it says refers to a sustained practice, not
one-off acts.35 ROK points to examples of how these terms are used throughout
various provisions of the FTA to refer, in its view, to formal laws, rules, policies
or procedures promulgated by the State, as opposed to informal, isolated, illicit,
illegal or unsanctioned conduct of individual officials.36

54 ROK argues that this is in line with the object and purpose of the FTA
which is, among others, to “establish clear and mutually advantageous rules
governing ... trade and investment” [emphasis added].37 ROK also relies on a
negotiation history footnote to the current Art 11.1.3(b) of the FTA, stating that
“‘powers’ refers to any regulatory, administrative, or other governmental
powers”.38 This, ROK submits, confirms that “measures adopted or maintained
by” only includes the formal exercise of regulatory, administrative or
governmental power.39
55 ROK highlights the decision of the international tribunal in Waste
Management, Inc v United Mexican States (II), ICSID Case No. ARB(AF)/00/3,
Award (30 April 2004) (“Waste Management v Mexico”), a case concerning the
North American Free Trade Agreement (“NAFTA”). There, the tribunal
considered whether a mayor’s statement to the effect that “the obligation to
contract [the claimant enterprise’s] services will be eliminated” constituted a
“measure” tantamount to expropriation under Art 1110(1) of the NAFTA. The
tribunal (at [161]) held that it did not, reasoning that:
... even if a unilateral and unjustified change in the exclusivity
obligation could have amounted to an expropriation, no
legislative change was in fact made. The Claimant argued that
this statement ‘effectively repealed the law’ but the Tribunal
does not agree. The Mayor was not purporting to exercise
legislative authority or unilaterally to vary the contract. He was
not intervening by taking some extra-legal action, as the Mayor
of Palermo did when he intervened in the ELSI case. He was
saying what ought to be done, in his view, to allay public
concerns, concerns which did in fact exist at the time.
Individual statements of this kind made by local political figures
in the heat of public debate may or may not be wise or
appropriate, but they are not tantamount to expropriation
37 CWS at paras 138–140. ↩
38 CWS at para 142. ↩
39 CWS at para 143. ↩
[Page 25]
unless they are acted on in such a way as to negate the rights
concerned without any remedy. In fact no action was taken of
the kind threatened at the time or later. ...
56 ROK relies on this to show that a “measure” should involve some formal
exercise of governmental rule-making or enforcement authority, and not just
comments by a public official expressing a desire or intention that something
be done.40
57 Applying its interpretation of “measures adopted and maintained”, ROK
argues that none of the Impugned Acts involved any exercise of State authority.
Rather, ROK’s officials made informal remarks with no legal effect or binding
force.41 These were illegal, illicit and unsanctioned conduct, for which the
officials were promptly prosecuted by Korean authorities.42
58 Mason’s position is that the phrase “measures adopted or maintained”
encompasses a broad range of formal and informal actions of the State,
including conduct in the purported exercise of executive authority, the abuse of
power by governmental officials, and conduct that is ultimately ultra vires.43
59 Mason submits that the ordinary meaning of “measure” is generic,
broad, inclusive and open ended, covering both formal and informal action.44 In
particular, “measure” includes a “procedure, requirement or practice”, which
could arise from acts or conduct and need not be in writing, and may include an

[Page 26]
informal state of affairs that does not have the force of law.45 The phrase
“adopted or maintained” merely sets out the two temporal conditions of a
measure – by way of the measure being taken, or by its persistence over time.46
60 Mason submits that ROK’s narrow interpretation of “measures” would
run counter to the FTA’s object and purpose, as host States would be able to
escape their obligations by avoiding formal governmental decision-making
processes and engaging in informal conduct.47 Such misconduct or abuses of
authority are precisely the kinds of action that would cause foreign investors
harm, and this militates against interpreting the FTA in a manner which carves
out such conduct from its substantive protections.48 Under customary
international law, States can be internationally responsible for conduct by a
person or entity empowered to exercise governmental authority even if such
conduct is informal, illegal or ultra vires.49 Mason further submits that the
negotiating history footnote to Art 11.1.3(b) of the FTA that ROK relies on is
irrelevant, as it is concerned only with measures adopted or maintained by non-
governmental bodies, and not with the acts of governments and authorities.50
61 Mason cited the judgment of the International Court of Justice (“ICJ”)
in Fisheries Jurisdiction (Spain v Canada) (Jurisdiction) [1998] ICJ 432
(“Fisheries Jurisdiction”) at [66] as support for its interpretation of “measures”
as “in its ordinary sense ... wide enough to cover any act, step or proceeding,
45 DWS at para 67(c). ↩
46 DWS at para 71. ↩
47 DWS at para 81. ↩
48 DWS at para 83. ↩
49 DWS at para 82. ↩

[Page 27]
and imposes no particular limit on their material content or on the aim pursued
thereby”.51
62 Applying its interpretation of “measures adopted or maintained”, Mason
submits that the Impugned Acts fall within the terms “requirement” or
“procedure”, in so far as ROK’s officials exercised (and abused) the authority
granted or delegated to them under Korean law.52 These were not private
infractions which they could commit as private citizens; they needed to act
under the auspices of official authority to perpetuate their illegal scheme.53
Mason further submits that ROK does not cure a breach of its substantive
obligations under the FTA through its alleged disavowal of the conduct of its
errant officials by prosecuting and convicting them.54
63 There appear to be two distinct points in ROK’s submission. The first is
that the Impugned Acts lacked the requisite formality to qualify as “measures”.
The second is that they were illegal acts which had been promptly prosecuted
by the Korean authorities, and so could not be said to be adopted or maintained
by ROK. Neither point is persuasive. On the first point of formality, the word
“measures” does not in its ordinary meaning entail any degree of formality. We
would agree with the opinion of the ICJ in Fisheries Jurisdiction at [66] that “in
its ordinary sense the word is wide enough to cover any act, step or proceeding”.
Indeed, executive action does not need to take written form: government
51 DWS at paras 86–87. ↩
52 DWS at paras 89–93. ↩
53 DWS at para 91. ↩
54 DWS at para 84. ↩
[Page 28]
officials may communicate on behalf of the executive orally, whether in person
or by telephone. There is nothing in the text or context of the FTA indicating
that any narrower meaning should be placed upon the word “measure”. The
general definition provided in Art 1.4 of the FTA that measure “includes any
law, regulation, procedure, requirement or practice” does not suggest any
limitation on the word. The definition is phrased inclusively rather than
exclusively. Some of the examples listed in the definition can be done
informally without requiring any degree of formality. Thus, while the first two
examples given, namely laws and regulations, are formal in the sense that they
would need to take a form stipulated by the lawmaking procedures of that State,
the other three examples, namely procedures, requirements and practices, can
all be formal or informal, written or unwritten.
64 As for the second point of illegality, there is no basis to read the word
“measures” as limited to measures that are lawful under the law of the State
concerned. Government officials may indeed take steps that are against the law
of the State but that does not of itself mean that those acts were not undertaken
by them as officials of the government, and so adopted or maintained by the
State. It may be that an act of an official which is illegal is then disavowed or
repudiated by the government. At that point it may (depending on the facts)
cease to be “maintained” by the State and if any loss historically suffered by the
investor from the now repudiated illegal act is fully compensated then there
would be no more loss for which an award would be made in an arbitration
under the FTA. The question of loss would however be a matter for the tribunal
in such a case to determine. The subsequent disavowal or repudiation of a
measure as illegal would not nullify the historical adoption or existence of the
measure.
[Page 29]
65 We also accept Mason’s submission that reading down the word
“measure” to exclude informal or illegal acts would run counter to the FTA’s
object and purpose, which is to provide investment protection to investors of the
other party. Where investor protection is concerned, there is no rational
distinction to be drawn between formal and informal acts or between legal and
illegal acts.
66 We now turn to the Relating To Objection.
67 Parties agree that the phrase “relating to” requires a “legally significant
connection” between the Impugned Acts and Mason or their investment:
Swissbourgh at [189].55 This requirement is not capable of simple definition and
must be examined case-by-case, but it clearly excludes measures which merely
affect an investment, or bear a purely incidental connection to it: Swissbourgh
at [195]. Both parties acknowledge this much,56 but part ways in their
understanding of what else a “legally significant connection” entails.
68 ROK relies on the factors identified in Lone Pine Resources Inc v The
Government of Canada, ICSID Case No. UNCT/15/2, Final Award
(21 November 2022) at [403], namely:57

57 CWS at para 165(a). ↩
[Page 30]
69 Additionally, ROK submits that a measure affecting the claimant in a
“tangential or merely consequential way” was insufficient, citing Resolute
Forest Products Inc v Government of Canada, PCA Case No. 2016-13,
Decision on Jurisdiction and Admissibility (30 January 2018) at [242].58
70 ROK argues that the Tribunal was wrong to accept the facts as alleged
by Mason in finding that the “relating to” jurisdictional requirement was met,
because Mason as claimants in the Arbitration bore the burden of proving the
facts necessary to establish the Tribunal’s jurisdiction.59 Even if the Tribunal
had made its own factual findings on the “relating to” requirement, ROK urges
the court to review the Tribunal’s factual findings on a de novo basis.60
71 In the present case, ROK invites the court to consider two Seoul Central
District Court decisions in conducting a de novo review. They are the Seoul
Central District Court Decision 2020GaHap600079 dated 25 November 2022
(the “25 Nov 2022 Judgment”) and the Seoul Central District Court Decision
2020GoHap718 dated 5 February 2024 (the “5 Feb 2024 Judgment”)
(collectively, the “Subsequent Korean Court Judgments”). ROK points to
findings in the Subsequent Korean Court Judgments that supposedly establish
58 CWS at para 165(b). ↩
59 CWS at paras 168–169. ↩
60 CWS at para 175. ↩
[Page 31]
that the Impugned Acts did not affect NPS’s Merger vote, much less Mason or
their investment.61 Therefore, the “relating to” requirement is not met.62
72 Additionally, after the hearing of SIC/OA 15/2024 on 16 and 17 January
2025, ROK sought permission to tender an additional judgment, the Seoul High
Court Decision 2020GoHap920 dated 3 February 2025 (the “3 Feb 2025
Judgment”).63 According to ROK, the judgment affirmed and upheld various
findings in the 5 Feb 2024 Judgment that ROK relied on.64 Mason objected,
arguing that the 3 Feb 2025 Judgment was of negligible probative value, and
granting permission to ROK would cause unnecessary delay.65 We granted ROK
leave to adduce the official copy and translated excerpts of the 3 Feb 2025
Judgment, and granted both parties leave to file brief comments on the relevance
of the judgment to this matter. Parties duly did so.
73 ROK submits that the 3 Feb 2025 Judgment is highly relevant because
it affirms key findings in the 5 Feb 2024 Judgment which ROK relies on to
advance the Relating To Objection (as well as the Natural Justice Objection,
which we consider at [142]–[143] below). In essence, the 3 Feb 2025 Judgment
increases the probative value of these findings, since the judgment was issued
by a second instance court acting as a “final trier of fact”.66

[Page 32]
74 Even if the Impugned Acts affected Mason or their investment, ROK
argues that there was no “immediate and direct effect”, as is allegedly required
to establish a “legally significant connection”.67
75 Mason’s position is that a “legally significant connection” is one that is
more than merely incidental or tangential, and that an “immediate and direct
effect” is not required.68 Mason argues that the ordinary meaning of “relating
to” is broad and generic.69 At the very most, it requires only that the
consequences of the breach not be too remote, and does not require that the
damage was foreseeable by the State at the time of the breach.70 The purpose of
the “relating to” requirement, Mason submits, is to exclude claims from wholly
indeterminate and unknown classes of potential claimants, not to introduce a
legal causation test as a threshold question.71
76 Mason defends the Tribunal’s approach in accepting pro tem the facts
alleged by Mason in determining whether a “legally significant connection”
existed.72 In any event, according to Mason, the evidence shows that the
Impugned Acts directly related to and specifically targeted Mason and their
investment.73 SC&T’s shareholders, including Mason, were specific targets of
ROK’s scheme to secure approval of the Merger to enable the succession plan

[Page 33]
of the current SEC Chairman, Lee Jae-young (“JY Lee”), at the expense of
SC&T’s shareholders.74 ROK’s measures were also part of a concerted,
nationalistic and public campaign against foreign investment funds, including
Mason.75
77 Concerning the Subsequent Korean Court Judgments, Mason submits
that they do not undermine the Tribunal’s findings that: (a) the Merger would
not have been approved but for ROK’s interference in NPS’s decision-making
processes; (b) the Merger Ratio was unfair to SC&T shareholders; and (c) the
Merger resulted in significant loss of shareholder value for SC&T
shareholders.76 Likewise, Mason submits, the 3 Feb 2025 Judgment, which
affirms the 5 Feb 2024 Judgment, does not undermine these findings in any
way.77
78 We accept that the phrase “relating to” operates to limit the group of
potential claimants in respect of any measure, either to restrict them from
claiming (if jurisdictional in nature, as assumed for this discussion) or from
succeeding in their claim (if going only to the merits). Further, we draw
assistance from the gloss on this phrase of a “legally significant connection”
derived from the partial award in Methanex Corporation v United States of
America, Partial Award (7 August 2002) at [137]–[139] which concerned the
equivalent NAFTA provision. Thus, the connection must be significantly more
than just any connection. However, the phrase “relating to” does not connote

76 DRS at paras 43–48. ↩
77 Defendant’s letter to court dated 28 February 2025 at para 3, 9. ↩
[Page 34]
any requirement that the measure be directed at the claimant or that the loss
suffered by the claimant be intended. In our view, intervention in relation to a
proposed merger of two companies has a legally significant connection to the
shares held in either company. The intervention directly concerns the interests
of shareholders in both companies. Moreover, a merger of companies is a
significant legal and economic event for both companies, and hence for the
shareholders in those companies. The actions of ROK’s officials alleged by
Mason therefore related to Mason and their investment.
79 In the award, this issue, while evaluated by the tribunal as a
jurisdictional issue, was considered on the basis that it accepted the facts pro
tem. We do not disagree with the Tribunal’s approach. Likewise, it is not for us
to make findings of fact afresh, or to revisit the factual substratum, before
determining whether a legal significant connection exists between the
Impugned Acts and Mason’s investment. For this reason, we also do not find
the Subsequent Korean Court Judgments or the 3 Feb 2025 Judgment to be
helpful to ROK. Those judgments do not alter our determination that the facts
as alleged by Mason can properly be characterised as measures relating to
Mason and their investment (see [49] above).
80 In relation to this issue, there is a preliminary question of whether the
Investor Objection is precluded by ROK’s not having challenged the Tribunal’s
preliminary ruling against it on this objection by making an application to court
within the prescribed time under s 10(3) of the International Arbitration Act
1994 (2020 Rev Ed) (“IAA”) and Art 16(3) of the MAL. Nonetheless, Mason’s
counsel agreed that we hear the arguments on the Investor Objection without
[Page 35]
first ruling on this preliminary question. Accordingly, we deal with the Investor
Objection first before returning to the preliminary question.
81 ROK argues that the Investor Objection is par excellence a jurisdictional
objection (citing Swissbourgh at [93]).78 In this case, Art 11.1.1 of the FTA
limits the FTA’s scope to measures adopted or maintained by a party relating to
“(a) investors of the other Party; (b) covered investments”.79 Moreover, the offer
to arbitrate in Art 11.16 is expressly limited to claims submitted by a “claimant”
– which is defined under Art 11.28 as “an investor of a Party that is a party to
an investment dispute with the other Party”.80
82 ROK adds that Mason’s entire time-bar objection under s 10(3) of the
IAA and Art 16(3) of the MAL is premised on the Investor Objection being
jurisdictional in nature.81
83 At the hearing, Mason’s counsel accepted that the Investor Objection is
jurisdictional – but only “up to a point”. According to him, only “binary”
questions which admit of a clear answer are properly jurisdictional.82 Here, the

[Page 36]
Investor Objection is not jurisdictional because it requires a nuanced analysis of: (a) the complex Mason investment structure; (b) the history of its investment thesis over many years; (c) expert evidence on Korean and Cayman law; and (d) treaty interpretation issues involving large volumes of jurisprudence from international courts and tribunals.83
Decision: The Investor Objection is jurisdictional in nature
84 We accept that the Investor Objection is jurisdictional in nature. We are not persuaded that an issue’s difficulty or fact-sensitive nature has any bearing on whether the issue is jurisdictional. Art 11.16 of the FTA entitles a claimant to submit claims to arbitration as specified therein, with such claimant being defined to mean “an investor of a Party that is a party to an investment dispute with the other Party” under Art 11.28. It follows from this wording that each party has made a standing unilateral offer to arbitrate only to investors of the other party who have an investment dispute with it.
(1) ROK’s case
85 ROK’s Investor Objection asserts that two broad requirements in the definition of an “investment” under Art 11.28 of the FTA have not been satisfied. These are: (a) the claimant must own or control, directly or indirectly, the Samsung Shares; and (b) the Samsung Shares needs to have the characteristics of an investment – including the commitment of capital or other
[Page 37]
resources, the expectation of gain or profit, or the assumption of risk. According to ROK, neither is satisfied.
(A) THE GP DID NOT OWN OR CONTROL THE SAMSUNG SHARES
86 ROK argues that GP neither owned nor controlled the Samsung Shares.
87 To establish ownership, ROK argues that Mason needs to demonstrate that GP held both the legal and beneficial interest in the Samsung Shares.84 On the facts, ROK argues that neither form of ownership is made out.
(a) In determining whether GP legally owned the Samsung Shares, ROK argues that Korean law should apply as the law of the place of incorporation of SC&T.85 Under Korean law, the entity registered in the shareholder registry will be the owner of the shares. In this case, ROK points out that the Cayman Fund (and not the GP) was registered on the shareholder register.86 ROK adds that in an application for registration of investment with the Korean Financial Services Commission (the “FSC Application”), the Cayman Fund (and not the GP) was listed as the foreign investor. This was significant as a false representation in this application carries administrative sanctions.87 Even if the Cayman Fund lacked legal personality under Cayman law, that has no bearing on whether GP can be the legal owner of the Samsung Shares under Korean
[Page 38]
law. It is improper and incorrect for Cayman law on legal capacity to displace Korean law on ownership.88
(b) In determining beneficial ownership, ROK argues that GP’s entitlement to an agreed incentive allocation (the “Incentive Allocation”) could not have given GP a beneficial interest in the Samsung Shares because it conflates GP’s uncertain right to profits with actual beneficial title.89 This is made clear by footnote 13 to Art 11.28 of the FTA which states “market shares, market access, expected gains, and opportunities for profit-making are not, by themselves, investments” [emphasis added].90
88 As for control, ROK argues that GP could not have had de jure or de facto control over the Samsung Shares because under Korean law, GP (which was not the named shareholder in Korea) would not have the legal capacity to exercise any shareholding rights. That GP had control over the Cayman Fund, does not necessarily mean that it had control over the Samsung Shares.91
(B) THE SAMSUNG SHARES DID NOT HAVE THE CHARACTERISTICS OF AN INVESTMENT
89 ROK begins by arguing that it is not enough for Mason merely to prove one of the listed characteristics of a qualifying investment under Art 11.28 of the FTA.92 They then go on to explain why none of the listed characteristics are present.
89 CWS at para 280; 16 January 2025 Transcript at p 188, lines 1–16. ↩
[Page 39]
90 First, ROK argues that GP did not make a “commitment of capital or other resources”.
(a) In relation to the commitment of “capital”, it is undisputed that GP did not make any cash contributions to the purchase price of the Samsung Shares. Instead, the shares were purchased with the Cayman Fund’s capital (injected by the contributions of Mason Capital LP (the “LP”)).93
(b) In relation to the commitment of “other resources”, ROK rejects Mason’s argument that GP committed resources such as “investment decision-making, management and expertise” which grew the value of the Cayman Fund’s assets. First, these were pre-investment activities that do not fall within the ambit of the FTA.94 Second, there is no factual basis to conclude that any pre-investment analysis was in fact performed by GP as opposed to another Mason entity. Indeed, Mason’s own witness explained that GP delegated much of its day-to-day operations to an investment manager.95
91 Second, ROK argues that GP did not assume any investment risk in relation to the Samsung Shares. This follows from the fact that GP made no “commitment of capital or other resources”. Having made no commitment, they would have incurred no risk of losing such (non-existent) commitment.96
93 CWS at para 295; CRS at para 202. ↩
[Page 40]
92 Third, ROK argues that GP did not have any “expectation of gain or profit” in relation to the Samsung Shares. They argue that the Incentive Allocation (GP’s only source of potential gain) was not directly linked to the performance of those shares. Instead, this allocation was calculated based on the Cayman Fund’s overall profits, irrespective of the individual performance of the Samsung Shares. In this sense, GP cannot be said to have had a separate expectation of profit or gain specifically in relation to the Samsung Shares.97
93 Last, ROK argues that the Cayman Fund did not hold the Samsung Shares for a sufficient duration. Although this characteristic is not expressly stated in the definition of “investment” in Art 11.28 of the FTA, it has nonetheless been recognised by a tribunal interpreting the same FTA.98 Having an investment of sufficient duration is also consistent with the requirement of a “commitment” of capital and resources and accords with the object and purpose of the FTA to strengthen the “close economic relations” and “promote economic growth and stability” between the US and ROK. These objectives are furthered through long-term investments which encourage commitments of capital. The protection in the FTA was not meant to extend to short-term investments arising out of purely speculative transactions. To illustrate this point, ROK characterises Mason’s alleged investments as those of a short-term speculator. Mason quickly acquired shares after the Merger announcement, even during Elliott’s proxy war, and then claimed losses when the Merger proceeded. This short-term speculative behaviour, ROK contends, falls outside the intended scope of the FTA’s investment protection provisions.99

(2) Mason’s case
94 Mason, on the other hand, argues that GP owned and controlled the Samsung Shares, and that the Samsung Shares had the characteristics of an investment.
(A) THE GP OWNED AND CONTROLLED THE SAMSUNG SHARES
95 In relation to ownership of the Samsung Shares, Mason argues that there is no requirement of proving beneficial ownership. Ownership simply refers to legal ownership – a uniformly accepted concept. In contrast, beneficial ownership is an amorphous and uncertain concept, and tellingly, ROK itself has not clearly articulated what it means. The FTA therefore does not require an investor to demonstrate anything as nebulous as beneficial ownership.100
96 Further, Mason argues that there is no “general principle of international investment law” that imposes the requirement of beneficial ownership. The very fact that ROK has recognised two schools of thought on the requirement of beneficial ownership means that there is no dominant view on the requirement which would elevate it to widespread customary international law.101
97 Even if there were a requirement of beneficial ownership, Mason argues that GP satisfies the requirement by virtue of the Incentive Allocation, which entitles GP to share in the benefits of ownership of the Cayman Fund’s assets.102
98 As for legal ownership, Mason argues that GP owned the Samsung Shares even though the Samsung Shares were registered in the Cayman Fund’s
[Page 42]
name. It is undisputed that Cayman law governs the Cayman Fund’s capacity to own property, and that the Cayman Fund has no legal personality under Cayman law. It is therefore nonsensical to suggest that the Cayman Fund is the legal owner of the Samsung Shares, merely because its name appears on the share registry. The only logically available conclusion is the application of Art 30 of the Korean Private International Law Act (Act No 966 of 1962) which refers to Cayman law to identify who actually owns the Samsung Shares.103
99 Even under Korean law, Mason emphasises that registration per se has no direct bearing on ownership rights. The Korean Supreme Court decision which ROK itself relies on confirms that registration only affects the determination of shareholders entitled to exercise shareholder rights, and not the attribution of share ownership.104 In relation to the “false representation” in the FSC Application, Mason points out that ROK’s own expert admitted that “administrative sanctions [from an erroneous FSC application] ha[s] no impact on the legal ownership”.105
100 In relation to control of the Samsung Shares, Mason points out that GP’s sole and exclusive management, control, and conduct over the business of the Cayman Fund is undisputed. GP was the only entity which could acquire assets as part of the business. It was the only entity which could make management decisions such as whether to sell shares and how to vote on those shares. In Mason’s view, the fact that GP was not the registered shareholder in the share registry did not negate GP’s control over the Samsung Shares. Indeed, they
103 DRS at para 93; DWS at para 232. ↩
104 17 January 2025 Transcript at p 109, lines 2–8; DRS para 101. ↩
[Page 43]
point out that ROK did not claim that GP’s acts – such as its vote on the Merger – were invalid or a nullity.106
(B) THE SAMSUNG SHARES HAD THE CHARACTERISTICS OF AN INVESTMENT
101 Turning to the characteristics of an investment, Mason emphasises that shares are a “quintessential form of investment”, that is expressly recognised in the definition of an “investment” under Art 11.28(b) of the FTA.107 They contend that shares are not peripheral assets that might test the boundaries of what constitutes an investment such as bonds or permits. Instead, shares are at the “beating heart” of what is classically seen to be investment.108 Mason argues that this alone is sufficient to satisfy the characteristics of an investment.
102 However, to the extent the list of characteristics in the definition of “investment” (including the “commitment of capital or other resources, the expectation of gain or profit, or the assumption of risk”) need to be additionally demonstrated, Mason argues that the existence of any one listed characteristic would suffice. They point to the definition’s use of the words “or” to demonstrate the disjunctive nature of these characteristics as illustrative examples.109
103 In any case, Mason argues that the Samsung Shares satisfied all the listed characteristics.
(a) First, there was clearly a commitment of capital by GP in the sum of KRW200bn (approximately US$180m) as of July 2015. It did

[Page 44]
not matter that the funds came from the LP (and not GP) because there is no requirement in the FTA that funds used to purchase an investment must come from the personal assets or accounts of an investor.110
(b) Second, there was an expectation of gain or profit from an appreciation in the value of the Samsung Shares.111
(c) Third, there was an assumption of risk in the depreciation of the value of the Samsung Shares which are especially volatile given that they are publicly traded.112
Decision: The GP owned the Samsung Shares
104 “Investment” is defined in Art 11.28 of the FTA to cover “every asset that an investor owns or controls, directly or indirectly, that has the characteristics of an investment”.
105 As recorded in the Decision on Preliminary Objections at [156], there is no dispute that under Cayman law the Cayman Fund lacks legal personality and the capacity to hold property, and that GP legally owns all partnership assets on trust in accordance with the terms of the partnership agreement. ROK’s contention is that, because the Cayman Fund was registered as the foreign investor with the Korean Financial Services Commission and as shareholder on the shareholder registries of SEC and SC&T, the Cayman Fund would be the owner of the Samsung Shares. An investor of Cayman nationality would not be protected under the FTA.
[Page 45]
106 We effectively reheard the parties’ arguments that had been made to the Tribunal. This included considerable argument concerning the effect of registration of the Cayman Fund as the owner of the Samsung Shares under Korean law. In our view, however, the answer can be arrived at in a relatively straightforward fashion. First and unsurprisingly, Korean private international law provides that corporations and other organisations are governed by the applicable law of the place of their establishment.113 This aligns with the general principles of private international law elsewhere, including in Singapore, the seat of the arbitration. Thus, for the Cayman Fund, one must look to Cayman Law to determine its legal nature and capacity. Cayman Law provides that any rights or property of the Cayman Fund “shall be held or deemed to be held” by GP.114 We assume for the sake of argument that, by entering the Cayman Fund’s name into the registers of SEC and SC&T as owner of the Samsung Shares, this had the effect of granting the Cayman Fund ownership rights over the Samsung Shares under Korean law. Even then, such rights would be held or deemed to be held by GP under Cayman law. This would make GP an investor under the FTA even if indirectly so via the Cayman Fund. For completeness, we add that we are not convinced that under Korean law a foreign entity without capacity to own property would be recognised as the owner of shares by virtue of being named on the shareholder register. We do not see any reason to import a separate requirement of beneficial ownership into the meaning of Art 11.28, which simply refers to assets that an investor “owns or controls, directly or indirectly”. The concept of beneficial ownership is not recognised in many civil law jurisdictions, and it would be anomalous to impose such a requirement under international investment law, especially since ROK’s own case is that ownership of the Samsung Shares is determined by Korean law. If there were
113 Decision on Preliminary Objections at para 139. ↩
114 Decision on Preliminary Objections at para 157. ↩
[Page 46]
such a requirement, however, we agree with Mason that it possessed a beneficial interest, since the Incentive Allocation entitled it to share in the profits gained from the Cayman Fund’s assets.
Decision: The GP controlled the Samsung Shares
107 In relation to the alternative limb of control of the Samsung Shares, it is undisputed that GP had sole and exclusive management, control, and conduct over the business of the Cayman Fund. It is significant that GP voted on the Samsung Shares when it came to the Merger, and there has been no suggestion that GP’s vote on the Merger was invalid or a nullity.
108 There is no meaningful distinction to be drawn between GP’s control over the Cayman Fund, and its control over the Samsung Shares. For all intents and purposes, GP’s control over the Cayman Fund directly translates to its control over the Samsung Shares.
Decision: The Samsung Shares had the characteristics of an investment
109 We accept Mason’s contention that the Samsung Shares were an investment. Shares in an enterprise are identified as a form that an investment may take in the definition of investment in Art 11.28 of the FTA. Mason established that the Samsung Shares entailed the commitment of capital and carried with them the expectation of gain or profit as well as the assumption of risk.
110 Two Singapore Court of Appeal decisions have considered the effect of Art 16(3) of the MAL, namely PT First Media TBK (formerly known as PT Broadband Multimedia TBK) v Astro Nusantara International BV and others
[Page 47]
and another appeal [2014] 1 SLR 372 (“Astro”), and Rakna Arakshaka Lanka Ltd v Avant Garde Maritime Services (Pte) Ltd [2019] 2 SLR 131 (“Rakna”).
111 Astro concerned a case where the arbitral respondent sought to resist the enforcement of an award in Singapore on the basis that the tribunal lacked jurisdiction. The arbitral claimant argued that the arbitral respondent could no longer raise such an argument as it failed to invoke Art 16(3) of the MAL within 30 days of the tribunal’s preliminary ruling on jurisdiction. The Court of Appeal rejected that argument. It held that the failure to invoke an “active” remedy of appealing a tribunal’s decision on jurisdiction under Art 16(3), does not preclude an applicant from invoking its “passive” remedy of resisting enforcement (at [132]). However, the Court of Appeal also noted, in obiter dicta, that they would “be surprised if a party retained the right to bring an application to set aside a final award on the merits under Art 34 on a ground which they could have raised via other active remedies before the supervising court at an earlier stage when the arbitration process was still ongoing” (at [130]).
112 Rakna came five years later and dealt with a case involving a non-participating respondent’s application to set aside an award for lack of jurisdiction. The Court of Appeal in Rakna interpreted Astro as carving out “one exception to the preclusive effect of Art 16” (at [54]). It then extended that by carving out another exception to the preclusive effect of Art 16(3), for cases where the respondent seeking to set aside an award did not participate in the arbitration (at [77]). This was justified on the basis that a non-participating respondent would not have contributed to any wasted time and costs for its failure to invoke Art 16(3) in a timely fashion. In justifying the exception, the Court of Appeal contrasted this situation with that of a participating respondent who “would have contributed to the wasted costs and it is just to say to such a
[Page 48]
respondent that he cannot then bring a setting-aside application outside the time limit prescribed in Art 16(3) though he can continue to resist enforcement” (at [75]).
113 Counsel for ROK contended that this exposition of the law by the Court of Appeal was merely obiter dicta and invited us to decide differently on the effect of Art 16(3).115 However, we need not consider this invitation further given our conclusion on the substance of the Investor Objection.
114 ROK’s jurisdictional characterisation of the Standing Objection is premised on the offer to arbitrate derived from the wording of Art 11.16.1(a) of the FTA. This offer to arbitrate is made only in respect of claims submitted by GP “on its own behalf” and for “loss or damage” that GP itself suffered. ROK stresses that this does not extend to proving the extent of loss.116
115 To satisfy this jurisdictional requirement, ROK maintains that it is not enough for a claimant to simply assert a breach and resultant loss. They argue that allowing such assertions to establish jurisdiction would lead to an “absurd” situation where any claimant will be able to satisfy the jurisdictional
[Page 49]
requirements of a treaty by simply asserting the facts which are required to establish jurisdiction over the claim.117
116 Much like ROK, Mason’s case also centres on the wording of the offer to arbitrate in Art 11.16.1(a). They submit that GP is simply required to submit a claim (ie, allege) that it had incurred loss or damage by reason of or arising out of ROK’s breach of an obligation. Mason emphasises that the actual determination on whether and to what extent GP actually sustained loss is a matter of merits.118
117 In response to ROK’s characterisation of this interpretation as “absurd”, Mason explains that the requirement to assert a breach and resultant loss serves the meaningful purpose of excluding claims for non-monetary relief and claims on behalf of third parties.119
Decision: The Standing Objection is not jurisdictional in nature
118 As we have already indicated, the proper construction of Art 11.16.1(a) of the FTA is that the offer to arbitrate is made only to claimants (ie, investors in respect of investments) and in respect of claims for the specified breaches. The claimant must submit such claims on its own behalf in respect of loss or damage that it claims to have incurred. This is a jurisdictional requirement, but it is satisfied by the claimant asserting facts that establish that it is making the claim on its own behalf and for its own loss. There is nothing illogical or absurd about this construction of the FTA. If the claimant fails to make good these
[Page 50]
assertions, then it would fail on the merits. Nonetheless, the tribunal’s determination of those merits would have been undertaken within its jurisdiction.
Decision: GP submitted a claim on its own behalf for losses it suffered
119 ROK contends that GP has no standing to bring a claim because it was in fact third parties (viz, the Cayman Fund and LP) which suffered loss, and not GP itself.120 However, as we explained in the previous section, proving these facts was not necessary to give the Tribunal jurisdiction. The sole question we are concerned with at this stage is whether GP brought a claim on its own behalf for loss or damage it suffered. This was amply borne out in the Notice of Arbitration filed by GP which brought a claim in its own name and for losses it allegedly suffered.
120 The final ground of challenge ROK brings is the Tribunal’s alleged breach of natural justice. This ground is premised on ROK’s dissatisfaction with the Tribunal’s refusal to admit into evidence the two Subsequent Korean Court Judgments which allegedly undermined the factual findings underpinning the Tribunal’s ultimate findings on matters of causation and breach.
121 In this regard, ROK claims it was denied a reasonable opportunity to present its case when:
(a) the Tribunal’s denied its request on 14 November 2023 to admit the 25 Nov 2022 Judgment; and
[Page 51]
(b) the Tribunal denied its request to refrain from closing the Arbitration proceedings so that ROK could review and consider whether it should seek leave to admit the 5 Feb 2024 Judgment.
122 The general principles governing breaches of natural justice are not in dispute and may be summarised as follows:
(a) The applicant must establish: (i) which rule of natural justice was breached; (ii) how it was breached; (iii) in what way the breach was connected to the making of the award; and (iv) how the breach did or could prejudice its rights: China Machine New Energy Corp v Jaguar Energy Guatemala LLC and another [2020] 1 SLR 695 (“China Machine”) at [86].
(b) In determining whether a party had been denied his right to a fair hearing by the tribunal’s conduct of the proceedings, the proper approach a court should take is to ask itself if what the tribunal did (or failed to do) falls within the range of what a reasonable and fair-minded tribunal in those circumstances might have done: China Machine at [98]. This is a fact-sensitive inquiry and has the following consequences:
(i) The tribunal’s conduct and decisions should only be assessed by reference to what was known to the tribunal at the material time: China Machine at [99].
(ii) The court should accord a margin of (or even “substantial”) deference to the tribunal in its exercise of procedural discretion: China Machine at [103]. This means that
[Page 52]
the court will not intervene simply because it might have done things differently.
(iii) Overall, the threshold for intervention is a relatively high one: there must be a real basis for alleging that the tribunal has conducted the arbitral process “either irrationally or capriciously”, or where the tribunal’s conduct of the proceedings is “so far removed from what could reasonably be expected of the arbitral process that it must be rectified”: China Machine at [103].
(c) In making procedural decisions, the tribunal is required only to give each party a reasonable right to present its case, after weighing the competing considerations, including the objective of ensuring a fair, expeditious, economical and final determination of the dispute: ADG and another v ADI and another matter [2014] 3 SLR 481 at [112].
(d) In determining whether the breach of natural justice (if any) caused prejudice, the real inquiry is whether the breach was merely technical and inconsequential or whether as a result of the breach, the arbitrator was denied the benefit of arguments or evidence that had a real as opposed to a fanciful chance of making a difference to his deliberations. The test is thus whether the material could reasonably have made a difference to the arbitrator, rather than whether it would necessarily have done so: L W Infrastructure Pte Ltd v Lim Chin San Contractors Pte Ltd and another appeal [2013] 1 SLR 125 at [54].
[Page 53]
(1) ROK’s case
123 The 25 Nov 2022 Judgment was a decision arising from a civil suit commenced by SC&T shareholders against ROK to seek compensation for losses suffered as a result of the MHW and NPS’s actions in influencing the result of the Merger. In the judgment, the court dismissed the shareholders’ claim against ROK for damages arising out of the Merger, and found that ROK did not affect NPS’s decision to vote in favour of the Merger.121
124 ROK argues that this judgment is highly relevant to the issue of causation in the Arbitration, and they therefore asked the Tribunal for permission on 14 November 2023 to admit the 25 Nov 2022 Judgment on the basis of “exceptional circumstances” as required by the procedural rules of the arbitral proceedings. In emphasising the materiality of the 25 Nov 2022 Judgment, ROK draws attention to the significant weight the Tribunal placed on the evidential value of certain Korean court judgments.122
125 In justifying “exceptional circumstances”, ROK explains that the judgment only became available to them after they had their last opportunity to submit evidence without leave from the Tribunal.123 They argue that, even if Mason objected to this late production, the Tribunal should have admitted the evidence subject to Mason’s right to comment and submit rebuttal evidence.
[Page 54]
ROK emphasises that the Tribunal’s primary concern should have been to have all relevant evidence before it made a decision.124
126 As far as prejudice is concerned, ROK claims the 25 Nov 2022 Judgment is especially significant because it considered the other Korean court judgments which formed the basis of the Tribunal’s findings on causation and breach. Yet, the Tribunal concluded that ROK’s actions did not influence the result of the Merger. In these circumstances, the 25 Nov 2022 Judgment would reasonably have made a difference to the outcome of the Arbitration.125
(2) Mason’s case
127 Mason begins by emphasising that the burden was on ROK to demonstrate “exceptional circumstances” to admit the 25 Nov 2022 Judgment.126 In this light, the Tribunal’s decision to refuse to admit the judgment because there were no “exceptional circumstances” fell within the range of what a reasonable and fair-minded tribunal could have done.127
(a) First, even though the 25 Nov 2022 Judgment had become available only after the parties filed their post-hearing briefs on 29 April 2022, ROK still waited for almost a year before seeking to admit it on 14 November 2023. ROK provided no explanation for this delay.128
[Page 55]
(b) Second, the request to admit the 25 Nov 2022 Judgment was in response to the Tribunal’s letter dated 10 October 2023 for parties to comment only on a “narrow and specific issue: a particular alternative methodology for calculating Claimants’ losses proposed by the Tribunal and the appropriate KRW-USD exchange rate”. The 25 Nov 2022 Judgment, which concerned issues of causation had nothing to do with the matters of quantum canvassed in the Tribunal’s letter.129
(c) Third, relevance is the bare minimum for admission of evidence and cannot alone constitute “exceptional circumstances”.130
128 Further, Mason points out that ROK did not protest after the Tribunal decided not to admit the 25 Nov 2022 Judgment. There is therefore no basis for finding a breach of natural justice where ROK “did not provide any fair – nor indeed any – intimation to the Tribunal … that they intended to assert that the Tribunal had acted in breach of the rules of natural justice” (CPU and others v CPX and another matter [2022] 4 SLR 314 at [61]) in excluding the evidence that ROK sought to admit.131
129 In any event, Mason argues that ROK suffered no prejudice as the 25 Nov 2022 Judgment would not have altered the outcome of the Arbitration in any meaningful way. Mason emphasises that the judgment would have been merely one piece of evidence among many for the Tribunal to consider. Given the extensive body of evidence already before the Tribunal, Mason asserts that
[Page 56]
it is highly unlikely that this single item, particularly one subject to appeal, could have meaningfully swayed the outcome of the Award.132
Decision: No breach of the fair hearing rule
130 In our view, there was no breach of natural justice in the Tribunal’s decision not to admit the 25 Nov 2022 Judgment into evidence. It was a case management decision that fell well within the bounds of what a reasonable tribunal was entitled to do when the request was made almost a year after the judgment came into existence with no explanation for the delay being offered. By then, the Tribunal’s deliberations were advanced, and the Tribunal was entitled to conclude that ROK already had a reasonable opportunity to present its case on the facts to which any findings in the 25 Nov 2022 Judgment might relate.
Decision: No prejudice suffered
131 Moreover, we find that the non-adduction of the 25 Nov 2022 Judgment did not prejudice ROK. This is because even if it had been admitted, it was only one more court judgment concerning facts that had already been ventilated before the Tribunal. It is unlikely that it would have had a material effect on the outcome of the Arbitration. As Mason rightly pointed out, the Tribunal’s reasoning rested on two findings: first, that but for ROK’s breach, the Merger vote would have been referred to the Experts Voting Committee instead of the Investment Committee of NPS,133 and second, that the Investment Committee would have abstained from or voted against the Merger.134 That was why ROK’s
[Page 57]
officials diverted the vote from the Experts Voting Committee to the Investment Committee. These findings were not challenged by the 25 Nov 2022 Judgment.
(1) ROK’s case
132 In essence, ROK takes issue with the Tribunal’s decision to prematurely close its proceedings, while it was in the midst of obtaining a copy of the 5 Feb 2024 Judgment. This judgment stemmed from the indictment against JY Lee and other associated executives for alleged stock price manipulation in relation to the Merger.135 In gist, the court found that the charges against JY Lee for illegal business practices and financial fraud to facilitate his succession in Samsung Group leadership were not made out.136
133 After being made aware of the 5 Feb 2024 Judgment, ROK promptly wrote in to the Tribunal on 15 February 2024, informing them about the significance of the judgment and that it was obtaining a copy. In the meantime, ROK requested that the Tribunal refrain from closing the proceedings. Mason objected on 16 February 2024, and ROK responded on 20 February 2024 clarifying that it was merely requesting the Tribunal to refrain from closing proceedings for the time being. However, within the same day, the Tribunal closed its proceedings and informed parties for the first time that it concluded its deliberations and was translating the finalised English draft award into Korean.137
137 CWS at paras 403–407 and 417. ↩
[Page 58]
134 In prematurely closing the proceedings, ROK alleges that the Tribunal did not comply with Art 29.1 of the UNCITRAL Arbitration Rules 1976 (“UNCITRAL Rules”), which provides that “[t]he arbitral tribunal may inquire of the parties if they have any further proof to offer or witnesses to be heard or submissions to make and, if there are none, it may declare the hearings closed.” According to ROK, this is a positive duty on the Tribunal’s part as recognised by Steven Chong J (as he then was) in Coal & Oil Co LLC v GHCL Ltd [2015] 3 SLR 154 (“Coal & Oil”) at [33]:138
At its ninth session, the Committee of the United Nations Commission on International Trade Law (“the UNCITRAL Committee”) was fully cognisant of the danger that aggrieved parties might apply to set awards aside on the basis that they had been denied an opportunity to present their case because of the premature closure of the hearings. That was why the representatives in the UNCITRAL Committee drafted Art 29 carefully to require tribunals to consult the parties in the arbitration before exercising its power to declare hearings closed: see Summary Record of the 16th Meeting of the United Nations Commission on International Trade Law, Ninth Session (A/CN.9/9/C.2/SR.16, 26 April 1976) at paras 83 to 85.
135 ROK adds that any possible prejudice to Mason could have been mitigated by giving Mason an opportunity to respond to the judgments in question.139 If delay was a genuine concern, ROK argues the Tribunal could have simply set a deadline for ROK to apply for leave to admit the 5 Feb 2024 Judgment, instead of closing the proceedings immediately.140
136 As discussed above (at [72]), after the substantive hearing in these proceedings, ROK sought and obtained leave to tender the 3 Feb 2025
[Page 59]
Judgment. ROK submits that this appellate judgment strengthens the probative value of the findings in the 5 Feb 2024 Judgment.141
(2) Mason’s case
137 Mason’s position is that there was no breach of natural justice in the Tribunal’s decision to close the proceedings.
138 In their view, Art 29.1 of the UNCITRAL Rules merely gives the Tribunal the power but not a duty to close proceedings. In fact, the very decision of Coal & Oil cited by ROK, rejected the argument that an equivalent provision in the 2007 Singapore International Arbitration Centre Rules imposed a duty (and not merely the power) to close proceedings (at [31], [35] and [36]):142
31 The key question is therefore whether the 2007 SIAC Rules, being silent on the issue, ought to be construed as imposing a duty on the tribunal to declare proceedings closed (as Mr Gabriel suggested) or whether it should be construed as conferring a mere power. I am of the view that the latter construction is preferable for four reasons.
...
35 The plaintiff’s argument, if accepted, would elevate a case management tool into a condition precedent for the release of the award. To my mind, imposing a duty on the tribunal to declare proceedings closed is inconsistent with the case-management function of a declaration of closure. ...
36 Third, the plaintiff’s construction is not commercially sensible. The plaintiff is unable to provide any satisfactory explanation why the declaration of closure is normatively
141 Claimant’s letter to court dated 18 February 2025 at para 3. ↩
[Page 60]
important enough to the arbitration process that such a duty should be imposed. ...
139 Mason argues that, at such a late stage of the proceedings where the English draft of the Award had already been finalised, the Tribunal was fully justified in deciding to close its proceedings.143 Otherwise, there would be no logical limit to how long the Tribunal should have waited before closing the proceedings. For instance, Mason points out that the Tribunal could also be asked to wait for the conclusion of any appeal against the 5 Feb 2024 Judgment, or indeed the conclusion of all other related proceedings in the Korean courts, including the compensation claim recently filed by NPS against Minister Moon, CIO Hong, and JY Lee.144
140 Insofar as prejudice is concerned, Mason repeats the point that the fact that the 5 Feb 2024 Judgment was just one item of evidence among a wealth of other evidence makes it improbable that it would have altered the outcome of the Arbitration in a meaningful way.145
141 Concerning the 3 Feb 2025 Judgment, Mason submits that it is not of any real relevance since it merely affirms the findings of the 5 Feb 2024 Judgment.146
Decision: No breach of the fair hearing rule
142 We again consider that the there was no breach of natural justice in the Tribunal’s decision not to admit the 5 Feb 2024 Judgment into evidence. It was
146 Defendant’s letter to court dated 28 February 2025 at para 3, 9. ↩
[Page 61]
another case management decision that fell well within the bounds of what a reasonable tribunal was entitled to do. Compared to the decision not to admit the 25 Nov 2022 Judgment, this decision was made at an even later stage, with the draft of the Award close to completion. Moreover, at that point ROK were simply asking that the Tribunal not close proceedings and wait for ROK to consider whether to make an application to adduce the 5 Feb 2024 judgment into evidence. Again, considerations of expedition and economy were legitimate considerations for the Tribunal. One significant consideration in this case is that there were multiple court proceedings, whether commenced or anticipated, that could have some bearing on the Arbitration. In such proceedings, judgments and appeals could continue to be rendered and filed. With this in mind, a line must be drawn somewhere in time. The outcome of the Arbitration should not have to wait for all relevant court proceedings to finally conclude. When to draw that line was squarely a matter for the Tribunal. We hold that the Tribunal did not act unreasonably in when and how it drew that line.
Decision: No prejudice suffered
143 On the question of prejudice, we find that the 5 Feb 2024 Judgment was just another piece of evidence. The fact that it was affirmed by the 3 Feb 2025 Judgment does not change this fact. The 5 Feb 2024 Judgment was again only one more court judgment concerning facts that had already been ventilated before the Tribunal. It would also not have affected the material findings of the Tribunal discussed at [131] above. It is unlikely that it would have altered the outcome of the Arbitration.
[Page 62]
144 Article 11.16 of the FTA functions as the jurisdictional gateway for all claims under Chapter 11 of the FTA. On a proper construction of the FTA, therefore, Art 11.16 supplies the preconditions for establishing the Tribunal’s jurisdiction. This includes the requirement that claims be filed by “claimants” that are “investors” (as defined in Art 11.28 of the FTA). However, the claimant need only “submit … a claim” that is properly characterised as a claim for a breach of an obligation under Section A (among others), which results in loss or damage to the claimant. Accordingly, while the Investor Objection is indisputably jurisdictional in nature, the Measures Objection, Relating To Objection and Standing Objection are not jurisdictional in the manner alleged by ROK. All that was required of Mason was an allegation of facts that amount to breach and loss. This had been duly made before the Tribunal since, according to our construction of the FTA, the Impugned Acts were indeed measures adopted or maintained by ROK and related to the Merger and shares held in SC&T and Cheil.
145 We find that Mason was an “investor” within the meaning of Art 11.28, and that GP submitted a claim on its own behalf for losses it suffered. Thus, even on a fresh review of the evidence in respect of the Investor Objection, we are unable to accept any of ROK’s jurisdictional objections.
146 Finally, ROK’s Natural Justice Objection fails because the Tribunal’s decisions not to admit the Subsequent Korean Court Judgments were both reasonable case management decisions. ROK also suffered no prejudice as it is unlikely either judgment would have materially affected the outcome of the Arbitration.
[Page 63]
147 For the above reasons, we dismiss ROK’s application to set aside the Award.
148 Mason, as the successful party, is entitled to costs that will generally reflect the costs it incurred, subject to the principles of proportionality and reasonableness: O 22 r 3(1) of the Singapore International Commercial Court Rules 2021 (“SICC Rules 2021”). The starting point is a subjective one. This does not mean that the successful party is entitled to recover whatever costs it incurred. But the assessment of what costs are reasonable will be directed at the costs that had in fact been incurred in the particular case, not the appropriate level of costs that might be incurred in similar cases: Senda International Capital Ltd v Kiri Industries Ltd [2023] 1 SLR 96 (“Senda”) at [52], [56]. We note that while the Court of Appeal’s decision in Senda was based on O 110 r 46 of the Rules of Court (2014 Rev Ed), the principles articulated in that case remain applicable to the assessment of costs under the new O 22 of the SICC rules, having regard to the wording of O 22 r 3(1): Reliance Infrastructure Ltd v Shanghai Electric Group Co Ltd [2024] SGHC(I) 8 (“Reliance Infrastructure”) at [18].
149 Under O 22 r 2(4) of the SICC Rules 2021, the court may fix or assess costs after an oral hearing or by way of written submissions. This affords wide discretion to the court in determining the procedure by which costs are to be assessed, including whether costs are to be fixed, assessed at the conclusion of the substantive proceeding, or assessed by way of a separate process after the conclusion of the proceedings: Senda at [69]. The court may also require parties
[Page 64]
to provide a costs schedule or submit costs estimates or budgets in the course of proceedings: Appendix C 5(B)(vi), para 54 of the SICC Rules 2021.
150 In considering the proportionality and reasonableness of costs incurred, the court may have regard to the non-exhaustive list of factors in O 22 r 3(2) of the SICC Rules 2021. Relatedly, the court should consider: (a) the complexity of the issues in the substantive proceeding; (b) the amount of costs claimed by the successful party; and (c) the nature and extent of the differences in the respective positions on costs taken by the parties: Senda at [70]. Because the inquiry into reasonableness is directed at the particular case, the costs incurred by the unsuccessful party can be a sound proxy for determining the appropriate level of costs: Senda at [75].
151 At the end of the substantive hearing, we directed parties to file costs schedules of what they would claim if they were successful.147 This was duly done.
152 Based on the costs schedules tendered by parties, the breakdown of their respective costs is summarised in the following table. Both parties’ costs schedules used multiple currencies, without any conversion into a common currency. Purely for the purposes of conducting a broad comparison, an indicative conversion to US dollars is given for each category of fees, based on the International Monetary Fund’s exchange rates for 14 February 2025, the date that both costs schedules were tendered.148

153 We find that the costs incurred by Mason in respect of Singapore counsel’s fees and disbursements were proportionate and reasonable and grant them in full. As is evident from the breakdown of costs, fees for Mason’s Singapore counsel were comparable to that of ROK’s counsel. Mason’s disbursements were significantly less than ROK’s disbursements. The overall quantum of these costs therefore appeared reasonable. Both parties also

provided adequate information relating to their Singapore counsel’s fees, in the form of the seniority and corresponding hourly rates of the Singapore counsel, a breakdown of the number of hours of work done, and explanations of the type of work those hours were incurred for, broken down by the stage of proceedings: see Senda at [73]; Form C1 of the SICC Rules 2021. Parties similarly provided a breakdown of their claimed disbursements. These costs appeared to be reasonably incurred. Thus, neither category of Mason’s costs could be said to be disproportionate or unreasonable.
154 We next address the costs in respect of foreign counsel. Both parties provided breakdowns of the hours worked and nature of work done, showing that the costs had been reasonably incurred. However, as can be seen from the table above, fees for Mason’s foreign counsel were significantly greater than fees for ROK’s foreign counsel. The former was approximately three times the latter. This disparity in quantum was difficult to fully justify considering the circumstances of the case.
155 We recognise that the amount at stake was significant, being the sum of approximately US$32m awarded by the Tribunal. The issues in the present case involved some degree of complexity. There were some issues of foreign law on which the parties would understandably have sought the assistance of foreign counsel. However, both parties had to prepare for the same issues, and there was no reason to expect Mason to incur significantly greater costs due to the nature of the issues or the amount at stake.
156 The number of foreign lawyers engaged by each party was comparable, and does not explain the disparity in costs. Mason engaged nine foreign counsel
[Page 67]
in total.155 Four of them, however, only did work in preparation for the main hearing on 16–17 January 2025.156 ROK engaged two foreign firms, each of which had between two and six lawyers working at any given time at different stages of proceedings.157 However, the higher costs incurred by Mason could at least partly be attributed to its decision to hire King’s Counsel as part of its team of foreign counsel, with correspondingly higher hourly fees. This was of course a decision Mason could reasonably have taken in the defence of its claim.
157 We recognise that there is no rule of law that one party’s costs are an upper limit on the costs claimable by the other party. There is no one exclusively reasonable and sensible manner of prosecuting the same claim even under the same circumstances. The test remains what is reasonable: Reliance Infrastructure at [22].
158 In the present case, it would be disproportionate and unreasonable to allow Mason the full extent of its costs for foreign counsel’s fees, considering the significant disparity between the parties’ costs, which cannot be fully justified. At the same time, some allowance must be given for Mason’s reasonable decisions in its choice of counsel. We therefore award US$1,200,000 to Mason in respect of its foreign counsel’s fees. While this is still much more than the amount incurred by ROK, we consider it to be a proportionate and reasonable amount.
[Page 68]
159 Accordingly, we award Mason costs of £324,469.38, US$1,609,898.72 and S$34,629.92, comprising:
(a) £312,493.33 and US$184,500 in respect of Singapore counsel’s fees;
(b) US$1,200,000 in respect of foreign counsel’s fees, a reduction from the amount of US$1,841,585 claimed by Mason; and
(c) S$34,629.92, US$25,398.72 and £11,976.05 in disbursements.
