I. INTRODUCTION

1. The 24 February 2023 non-disputing party submission of the United States of America (“the U.S. Submission”) confirms that Peru's jurisdictional objections are not only irreconcilable with the terms of the United States-Peru Trade Promotion Agreement (“TPA”) and the intent of the TPA parties, but also with the views of the U.S. Government. For example, the U.S. repeatedly confirms that the Article 10.18.1 limitation period can only start to run once the claimant has acquired knowledge that breach has occurred and the claimant has “incurred loss or damage" in the past tense. Accordingly, Peru's refusal to accept that Article 10.18.1 of the TPA "require[s] completed breach and injury" is incompatible with the U.S. Submission. Peru's argument that the limitation period begins once a claimant "first knew" the "legal basis" of a future breach is equally incompatible with the U.S. Submission. That would expose the TPA parties to unripe claims for breaches based on future State conduct that may never occur and for damages that may never be incurred. Unsurprisingly, the U.S. Government does not endorse that absurd result. Nor does it endorse any of Peru's remaining attempts to contort the jurisdictional provisions of the TPA.

2. The U.S. also expresses its views on the content of the customary international law minimum standard of treatment and the means of establishing the content of the minimum standard. In this respect, the U.S. Submission has no bearing on the merits of Freeport's claims and is thus ultimately of limited assistance to the Tribunal. For example, the U.S. opines that a claimant carries the burden of proving a rule of customary international law and may only make limited recourse to prior decisions in doing so. Yet, the U.S. supports its views almost exclusively by reference to prior decisions and the U.S. Submission cannot be interpreted as seeking to impose a greater standard on Freeport than the U.S. imposes on itself in asserting its own views on the content of customary international law. Thus, under the approach taken by the U.S. in its submission, Freeport has established the rules of customary international law relevant to the claims Freeport makes. The U.S. Submission on the content of the minimum standard has limited relevance to Freeport's claims and thus provides little, if anything, for the Tribunal to consider. For example, the U.S.'s opinion that the minimum standard of treatment does not contain independent “legitimate expectations" or "transparency" obligations is ultimately irrelevant to resolving Freeport's argument that those concepts are relevant to assessing an alleged breach of the minimum standard.

II. THE UNITED STATES' VIEWS ON THE JURISDICTIONAL PROVISIONS OF THE TPA SUPPORT FREEPORT'S ARGUMENTS

3. The U.S. Submission supports Freeport's arguments on the jurisdictional provisions of the TPA and confirms that the Tribunal has jurisdiction over Freeport's claims. First, the U.S. agrees with Freeport that the three-year limitation period set forth in Article 10.18.1 only begins to run once a breach has occurred and loss or damage has been incurred, and that a separate limitation period applies to each independently actionable breach. Second, the U.S. Submission confirms that the rule against the retroactive application of treaties does not bar claims challenging post-entry-into-force measures that independently support a cause of action, such as Freeport's claims challenging final and enforceable SUNAT Assessments that indisputably post-date the TPA's entry-into-force. Third, the U.S.'s view that the term "taxation measures" in Article 22.3.1 contemplates measures that apply or enforce, or fail to apply or enforce taxes, supports Freeport's argument that non-tax measures such as penalties and interest are not "taxation measures" under the TPA. Finally, the U.S.'s recognition of the distinction between investment agreement claims submitted on behalf of an investor and on behalf of an enterprise under Article 10.16.1 supports Freeport's view that it is SMCV's reliance on the Stability Agreement, not Freeport's, that is relevant for the investment agreement claims Freeport submitted on behalf of SMCV.

A. THE UNITED STATES' VIEWS ON ARTICLE 10.18.1 SUPPORT FREEPORT'S ARGUMENTS

4. The U.S. Submission supports Freeport's argument that Article 10.18.1 of the TPA does not bar Freeport's claims for breaches of the Stability Agreement and Article 10.5 of the TPA. Article 10.18.1 of the TPA provides that:

No claim may be submitted to arbitration under this Section if more than three years have elapsed from the date on which the claimant first acquired, or should have first acquired, knowledge of the breach alleged under Article 10.16.1 and knowledge that the claimant (for claims brought under Article 10.16.1(a)) or the enterprise (for claims brought under Article 10.16.1(b)) has incurred loss or damage.1

5. As Freeport explained in its previous submissions, Freeport acquired knowledge of Peru's breaches of the Stability Agreement and Article 10.5 of the TPA after the 28 February 2017 cut-off


1 CA-10, United States-Peru Trade Promotion Agreement (“TPA”), Article 10.18.1 (emphasis added). ↩

[Page 3]

date that the Parties agree applies to Freeport's claims.2 Therefore, Freeport could only have acquired knowledge of those breaches and the respective losses or damages incurred after 28 February 2017.3

6. The U.S. Submission contradicts Peru's tortured interpretation of Article 10.18.1. The U.S. correctly observes that the limitation period cannot begin before breach and loss have occurred, thus contradicting Peru's argument that the limitation period begins to run once a claimant acquires knowledge of the "legal basis” upon which it “would incur” loss or damage in the future.4 Peru's erroneous argument would mean that the limitation period would have started not only before any of the Assessments were final and enforceable, but years before SUNAT even notified SMCV of most of the Assessments and before most of the relevant fiscal years had even started.5 That would encourage claimants to submit unripe and uncertain investment treaty claims based on future SUNAT assessments that might never be rendered or might never become final and enforceable and damages that may never be incurred.6 Unsurprisingly, the U.S. Submission does not support that untenable result, which would be contrary to

the goal of promoting "legal stability and predictability for potential respondents and third parties" because the respondent State would be exposed to claims for future assessments and damages not yet incurred.7

1. The United States' Submission Supports the Timeliness of Freeport's Claims Alleging Breaches of the Stability Agreement

7. The U.S. Submission supports the timeliness of each of Freeport's claims for breach of the Stability Agreement and shows why Peru's arguments are untenable.

8. First, the U.S. Submission confirms that Freeport could not have acquired knowledge of the breach and loss resulting from each Assessment until the relevant assessment became final and enforceable. Conversely, the U.S. Submission directly contradicts Peru's argument that the limitation periods for Freeport's claims started before SMCV incurred loss or damage.

(a) The U.S. Submission is consistent with Freeport's argument that a claimant cannot "incur" loss or damage from a SUNAT assessment until it becomes final and enforceable.8 The U.S. recognizes that the limitation period cannot begin before a claimant has incurred loss and damage. As Freeport explained,9 under Peruvian law, SUNAT assessments are not immediately enforceable against a taxpayer upon notification.10 Instead, the taxpayer is afforded an opportunity to request that SUNAT, and then the Tax Tribunal, reconsider an assessment before it becomes final and enforceable.11 As Freeport explained and as Peru admits, SUNAT cannot enforce assessments until that administrative process is complete.12 The Tax Code explicitly

precludes SUNAT from doing so.13 And as Peru and its experts admit, “SMCV was under no legal obligation to pay the Assessments" until the administrative process was complete and an assessment does not become "binding" on a taxpayer until the administrative process for that assessment is complete.14 Peru even admits that a claimant cannot incur loss or damage from a legal obligation until "that legal obligation will actually result in the victim making the payments; if not, then the victim has not suffered (and will not suffer) any actual damage."15 The conclusion by the U.S. that “the term 'incurred' broadly means 'to become liable or subject to" is fully consistent with Freeport's arguments.16 There was no payment obligation that SUNAT could enforce until each assessment became final and enforceable.17 Thus, SMCV could not be subjected to a payment obligation and could not become liable to pay an assessment until it became final and enforceable.18

(b) The U.S. recognizes that Article 10.18.1 requires knowledge that breach has occurred and that the claimant “has incurred loss or damage,” in the past tense.19 It thus cannot be reconciled with Peru's refusal to accept that Article 10.18.1 "require[s] completed breach


enforceability...."); RER-2, Report of Expert in Peruvian Civil Law Rómulo Morales Hervias (4 May 2022) ("Morales I"), ¶ 102 (“[T]he act (the Assessment and Penalty Resolution) is not enforceable by SUNAT until such time as it is possible for the administrative procedure to be brought to an end.").

and injury."20 Nothing in the U.S. Submission supports Peru's argument that the limitation period runs from the date a claimant acquires knowledge of the "legal basis" upon which it “would incur” loss or damage in the future.21 As Freeport explained, a government's "legal basis" for future conduct alone neither breaches the TPA nor causes loss to the investor.22 To give rise to a claim for breach of an investment agreement or the TPA, the Government must adopt a measure that breaches its obligations and that causes loss or damage.23 Here the measures that Freeport alleges have breached the Stability Agreement and have caused loss or damage are each of the final and enforceable Assessments, not the "legal basis” for them.24

(c) Freeport does not disagree with the U.S. Submission that “a claimant may have knowledge of loss or damage even if the amount or extent of that loss or damage cannot be precisely quantified until some future date.”25 That submission is consistent with Freeport's argument that the relevant point in time is not the moment when the amount of loss or damage can be "precisely quantified" but, rather, the moment when an assessment is final and enforceable against a taxpayer.26 The limitation period cannot commence before an assessment is final and enforceable not because loss or damage cannot yet be "precisely quantified" but because loss or damage cannot occur until that time.

[Page 7]

(d) Nothing in the U.S. Submission contradicts Freeport's argument that Peruvian law governs the question of when a SUNAT assessment results in breach of a Peruvian law stability agreement. As Freeport explained, in the case of royalty and tax assessments, Peruvian courts have recognized that a contractual breach occurs when the assessment becomes final and enforceable.27 For example, in the Poderosa case, the Peruvian courts held that the alleged breaches of Poderosa's stability agreement occurred, and the Peruvian limitation period for breach-of-contract claims started to run, when the Tax Tribunal issued its resolutions.28

(e) The U.S. position that the limitations period is a “clear and rigid" requirement not subject to “suspension,” “prolongation” or “other qualification” is fully consistent with Freeport's position.29 As Freeport has explained, a SUNAT assessment does not result in breach and loss capable of triggering the limitation period until the administrative process for that assessment is complete.30 Thus, Freeport does not argue that the administrative process suspends or tolls the limitation period as Peru claims.31 Instead, Freeport's position is that breach and loss do not occur and hence the limitation period does not start until the administrative process for a SUNAT assessment is complete.32 Moreover, Peru is wrong when it argues that the administrative process suspends the enforceability of an assessment.33 An assessment does not become final and enforceable until the

9. Second, the U.S. Submission is consistent with Freeport's argument that each final and enforceable assessment resulted in a separate breach of the Stability Agreement and separate loss to SMCV, and thus gives rise to a separate claim for breach of the Stability Agreement with a separate limitation period.35 Nothing in the U.S. Submission supports Peru's argument that a single limitation period applies for separate claims if they result from a "series of similar and related actions by a respondent state.”36

(a) The U.S. Submission is consistent with the plain terms of Article 10.18.1, according to which a single limitation period applies for a "claim," not for "a series of similar or related" claims.37 As Freeport has explained, each of the Assessments gave rise to an independent cause of action for breach of the Stability Agreement and caused separate loss or damage to SMCV on the dates they became final and enforceable.38 Thus, Freeport could not have acquired knowledge of Peru's breaches of the Stability Agreement or the loss or damage resulting from any of Peru's breaches until those dates. Peru's argument that Freeport should have brought a claim in 2009 for future royalty and tax assessments that had not yet been rendered, for royalty and tax debts that had not yet been incurred, would encourage investors to bring claims before they are ripe for adjudication.39 Nothing in the U.S. Submission supports giving Article 10.18.1 that perverse effect.

limitation periods apply to separate causes of action even if they are based on a series of similar or related actions.40

(b) The U.S. correctly recognizes that "a legally distinct injury can give rise to a separate limitations period.”41 As Freeport explained, each final and enforceable Assessment caused a legally distinct injury because it gave rise to separate causes of action for breach of the Stability Agreement.42 Peru and its experts do not dispute that SMCV could have brought separate contract claims for breach of the Stability Agreement for each SUNAT Assessment irrespective of whether they are factually or legally related.43

(c) Nothing in the U.S. Submission supports Peru's argument that independent causes of action can be consolidated into a single cause of action with a single limitation period if they are "similar” or “related.”44 The U.S. Submission observes that “where a ‘series of similar and related actions by a respondent state' is at issue, a claimant cannot evade the limitations period by basing its claim on ‘the most recent transgression' in that series.”45 That reflects the long-standing U.S. position that Freeport mentioned in the Rejoinder on

Jurisdiction—a claimant cannot evade the limitation period by arguing that similar and related actions concerning a single cause of action each produce a separate cause of action.46 But that does not mean that the distinct causes of action Freeport alleges give rise to a single limitation period if they are based on similar legal reasoning as Peru argues.47 This is clear from the U.S.'s reliance on Grand River v. U.S.A. which, as Freeport explained, supports applying separate limitation periods to distinct causes of action even if they are based on similar or related Government conduct. As Freeport explained, in Grand River, the tribunal concluded that claims challenging various escrow statutes implementing a Master Settlement Agreement between U.S. tobacco producers and 46 U.S. state governments requiring the states to enact escrow statutes were time barred.48 However, the tribunal concluded that claims challenging related, complementary legislation that the state governments adopted after the cut-off date were not time-barred.49

(d) The U.S. Submission does not support Peru's argument that, after SUNAT notified SMCV of the 2006-2007 Royalty Assessments, every single Assessment was "essentially guaranteed (predestined)” to come out the same way.50 The U.S. Submission nowhere suggests that Peru's breaches could have been “predestined” when Peru itself admits that none of SUNAT's or the Tax Tribunal's resolutions had any precedential effect and admits that even the Supreme Court's decision in the 2008 Royalty Case was limited to "th[at] specific dispute" and had no “erga omnes precedential effect.”51

2. The United States' Submission Supports the Timeliness of Freeport's Claims Alleging Breaches of Article 10.5 of the TPA

10. The U.S. Submission similarly supports the timeliness of each of Freeport's claims for breach of Article 10.5 of the TPA. As Freeport explained, Freeport acquired knowledge of each of Peru's Article 10.5 breaches after 28 February 2017.52 Nothing in the U.S. Submission suggests that Freeport should be deemed to have acquired knowledge of those breaches before those dates.

i. The United States' Submission Supports the Timeliness of Freeport's Article 10.5 Claims Challenging Royalty Assessments

11. For the same reasons set forth above in Section II.A.I, the U.S. Submission is consistent with Freeport's argument that the 2009, 2010-2011, Q4 2011, 2012, and 2013 Royalty Assessments each breached Peru's obligations under Article 10.5 on the dates upon which each assessment became final and enforceable.53 The U.S. does not contradict Freeport's argument that the standard for determining when a cause of action for breach of the TPA arose is the same as the standard for determining when a cause of action for breach of the Stability Agreement arose, which Peru does not dispute.54 As explained above, the U.S. Submission is consistent with Freeport's argument that each Assessment created a separate cause of action when it became final and enforceable.

ii. The United States' Submission Supports the Timeliness of Freeport's Article 10.5 Claims Based on Due Process Violations

12. The U.S. Submission is consistent with Freeport's argument that its Article 10.5 claims based on due process violations in the Tax Tribunal proceedings are timely.55 As Freeport explained, it only acquired knowledge of the due process breaches in the 2006-2007 and 2008 Royalty Cases in 2021 when it received President Olano Silva's email correspondence in response to a request for access to public information or, in the alternative, in 2019, when SMCV began investigating the decisions in the


compliance in any of SMCV's administrative challenges or confirm any of the Assessments based on a precedent of mandatory compliance. Nor did SUNAT or the Tax Tribunal ever indicate that they were bound by the 2006-2007 or 2009 Royalty Assessments in deciding SMCV's challenges to any of the subsequent assessments.") (citing CER-8, Hernández II, ¶ 127 (“SUNAT could have arrived at a different legal conclusion in each assessment, for example, as a result of a change in position or by order of the Tax Tribunal. Thus, SMCV could not have anticipated the content of any particular royalty or tax assessment based on SUNAT's interpretation of the mining provisions in its first-issued assessment."); id. ¶ 126 (“Each Royalty and Tax Assessment is an independent administrative act because the legal effects of one did not extend to the other.")).

2006-2007 and 2008 Royalty Cases in preparation for filing this arbitration.56 Nothing in the U.S. Submission supports Peru's argument that a respondent State can avoid liability by successfully hiding the evidence of its Treaty breaches.57

13. The U.S. Submission endorses Freeport's argument that the applicable standard for constructive knowledge under Article 10.18.1 is one of reasonable prudence and diligence.58 As Freeport explained, Ms. Villanueva's initials on the work route of the resolution in the 2008 Royalty Case and the copy-pasting of that resolution in the 2006-2007 Royalty Case were insufficient to result in constructive knowledge of due process violations.59 The resolutions alone did not reveal the flagrant violations at the core of Freeport's due process claims—that President Olano Silva intervened on the merits of the 2008 Royalty Case and that she was the reason Chamber No. 10 adopted a copy-paste version of the resolution in that case in the 2006-2007 Royalty Case. Instead, the irregularities on the face of the resolutions merely confirm those grave irregularities.60 Thus, reasonable prudence and diligence did not call for Freeport to investigate Peru's due process violations at the time SMCV received the Tax Tribunal resolutions in the 2006-2007 and 2008 Royalty Cases.

14. The U.S.'s recognition that the standard of reasonable prudence and diligence applies contradicts Peru's argument that a respondent State can avoid liability by playing hide and seek with the evidence until the limitation period expires. As Freeport explained, it would be utterly unreasonable to expect Freeport to have learned of Peru's due process violations earlier given the great lengths to which Peru and Ms. Olano Silva went to conceal that wrongful conduct from Freeport and SMCV.61 As Freeport explained, the Tax Tribunal did not disclose the egregious departures from the Tax Tribunal rules of procedure during the administrative process, nor when it notified SMCV of the resolutions in the 2006- 2007 and 2008 Royalty Cases.62 Moreover, Peru strenuously resisted disclosure of documents concerning the procedural irregularities in the 2006-2007 and 2008 Royalty Cases, baselessly arguing that relevant documents that Peru designated as “secret” under Peruvian law were not subject to disclosure.63 And then Peru produced no documents in response to the two requests for documents prepared, sent, or received by

iii. The United States' Submission Supports the Timeliness of Freeport's Article 10.5 Claims Based on Peru's Failure to Waive Penalties and Interest

15. Failure to Waive Penalties and Interest on the 2006-2007 and 2008 Royalty Assessments. The U.S. Submission is consistent with Freeport's argument that its Article 10.5 claims based on Peru's failure to waive penalties and interest on the 2006-2007 and 2008 Royalty Assessments are timely. As Freeport explained, Peru breached Article 10.5 (i) on 21 July 2017 when the Appellate Court notified SMCV of its decision arbitrarily and unreasonably refusing to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2006-2007 Royalty Assessments; and (ii) on 10 October 2017 when the Supreme Court notified SMCV of its decision arbitrarily and unreasonably refusing to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2008 Royalty Assessments.65 Nothing in the U.S. Submission contradicts Freeport's argument that, because the decisions of the contentious administrative courts are judicial acts, they support causes of action for breach of Article 10.5 independent from Peru's failures to waive the penalties and interest at the administrative level.66

16. Failure to Waive Penalties and Interest on the 2009, 2010-2011, 2011/Q4, 2012, 2013 Royalty Assessments and the Tax Assessments. For the same reasons set forth above in Section II.A.1, the U.S. Submission is consistent with Freeport's argument that its Article 10.5 claims based on Peru's failure to waive penalties and interest on the remaining assessments are timely. As Freeport explained,

iv. The United States' Submission Supports the Timeliness of Freeport's Article 10.5 Claims Based on Peru's Failure to Reimburse GEM Payments

17. The U.S. Submission is consistent with the timeliness of Freeport's claims for breach of Article 10.5 of TPA based on Peru's failure to reimburse SMCV for Q4 2011 to Q3 2012 GEM, which Peru does not dispute.68

B. THE UNITED STATES' SUBMISSION CONFIRMS THAT FREEPORT'S CLAIMS DO NOT REQUIRE RETROACTIVE APPLICATION OF THE TPA

18. The U.S. Submission supports Freeport's arguments that the non-retroactivity rule does not bar any of Freeport's claims. Article 10.1.3 of the TPA reiterates the general rule against the retroactive application of treaties reflected in Article 28 of the Vienna Convention on the Law of Treaties (the “VCLT”).69 Article 28 of the VCLT provides that:

Unless a different intention appears from the treaty or is otherwise established, its provisions do not bind a party in relation to any act or fact which took place or any situation which ceased to exist before the date of the entry into force of the treaty with respect to that party.70

19. The U.S. Submission supports Freeport's argument that the non-retroactivity rule is inapplicable because each of the Government acts or omissions upon which Freeport bases its claims are sufficient to support causes of action for breaches of the Stability Agreement and the TPA and indisputably occurred long after 1 February 2009, when the TPA entered into force.71 The recognition by the U.S. that Article 10.1.3 of the TPA does not modify the general rule against the retroactive application

[Page 15]

of treaties reflected in Article 28 of the VCLT contradicts Peru's arguments that the Tribunal lacks jurisdiction over “disputes” that began prior to the TPA's entry-into-force.72

20. First, the U.S. agrees with Freeport that the non-retroactivity rule does not apply to post- entry-into-force acts or facts that are sufficient to constitute a breach and are thus “actionable in [their] own right."73 As Freeport explained, because Chapter 10 of the TPA contains “bind[ing]" provisions regulating government “measures," it is government measures that can support a cause of action for breach of an investment agreement or the TPA and thus government measures are the acts or facts relevant for determining whether the non-retroactivity rule applies.74 Here, the non-retroactivity rule does not apply because each of the measures upon which Freeport bases its claims occurred long after 1 February 2009 and is sufficient to support a cause of action for breach of the Stability Agreement or the TPA.75


72 Compare U.S. Submission ¶ 2 n. 2 (observing that “[t]he phrase ‘for greater certainty' [in Article 10.1.3] signals that the sentence it introduces reflects what the agreement would mean even if that sentence were absent" and citing Article 28 of the VCLT), with Rejoinder on the Merits and Reply on Jurisdiction ¶ 779 (relying on international law authorities interpreting non-retroactivity provisions that applied to preexisting "disputes"); id. ¶ 783 (contending that “Claimant admits that the genesis of this entire dispute is MINEM's interpretation reflected in the June 2006 Report"). ↩

United States, NAFTA/ICSID Case No. ARB(AF)/99/2, Award, (11 October 2002) (“Mondev Award”), ¶ 70); Reply and Counter-Memorial on Jurisdiction ¶ 269 (arguing that the non-retroactivity rule does not apply because “the Assessments, arbitrary decisions refusing to waive penalties and interest, and arbitrary decision denying SMCV's GEM reimbursement request are 'orders or other regulatory measures imposing legal consequences on' Freeport and SMCV giving rise to 'actionable breach[es] in [their] own right."); Rejoinder on Jurisdiction ¶ 75(b) ("[E]ach of the post-entry into force measures that Freeport challenges as breaches of the Stability Agreement and the TPA would be 'independently actionable' irrespective of whether Peru earlier expressed its novel position on the scope of stability guarantees in the non-binding 2006 MINEM Report or any of the other reports and memoranda that Peru cites."). ↩

(emphasis added); id. at Article 10.1.3 (“For greater certainty, this Chapter does not bind any Party in relation to any act or fact that took place or any situation that ceased to exist before the date of entry into force of this Agreement.") (emphasis added)). ↩

75 See Rejoinder on Jurisdiction ¶ 72(a); Reply and Counter-Memorial on Jurisdiction ¶ 266 (“Freeport alleges that: (i) each final and enforceable Assessment breached the Stability Agreement on the dates identified in Table A of the Memorial; (ii) each final and enforceable Royalty Assessment breached Article 10.5 of the TPA on the dates identified in Table A of the Memorial; (iii) the arbitrary failure of the Supreme Court to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2008 Royalty Assessments and the arbitrary failure of the Appellate Court to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2006-2007 Royalty Assessments breached Article 10.5 of the TPA on 21 July 2017 and 10 October 2017, respectively, when the courts notified SMCV of their decisions; (iv) each of the remaining arbitrary failures to waive penalties and interest breached Article 10.5 of the TPA on the dates identified in Table B of the Memorial; and (v) Peru's arbitrary refusal to reimburse Q4 2011 to Q3 2012 GEM payments for activities related to the Concentrator breached Article 10.5 of the TPA on 22 March 2019 when SUNAT notified SMCV of its decision rejecting SMCV's reimbursement request. Each of these measures occurred long after 1 February 2009."). ↩

[Page 16]

21. Second, the U.S. recognizes that the non-retroactivity rule does not apply simply because pre-entry-into-force conduct is relevant to the challenged measures. Instead the U.S. opines that “a host State's conduct prior to the entry into force of an obligation may be relevant to determining whether the State subsequently breached that obligation.”76 The U.S. Submission thus supports Freeport's argument that the non-retroactivity rule does not apply merely because Mr. Isasi's non-binding June 2006 Report, the recently-surfaced June 2006 SUNAT Report, and the various pre-entry-into-force Government reports and memoranda that Peru cites are relevant to Freeport's claims.77 None of those reports and memoranda were capable of supporting a cause of action for breach of the Stability Agreement or the TPA because SMCV did not incur loss or damage from them.78 As Freeport explained, the Tribunal can and should take into account the factual background against which the complained-of measures took place in assessing the merits of claims that those measures breached the Stability Agreement and the TPA—but that does not place those measures beyond the Tribunal's temporal jurisdiction.79

22. Third, the U.S. Submission confirms that Article 10.1.3 merely "reflects" the general rule against the non-retroactivity of treaties set forth in Article 28 of the VCLT and thus contradicts Peru's attempt to distort that standard.

(a) The non-retroactivity rule only applies to claims that would bind Peru with respect to "any act or fact which took place or any situation which ceased to exist" before the TPA

entered into force.80 Thus, the U.S. Submission confirms that Peru is deeply misguided in its focus on “the birth of [Claimant's] dispute,” or “acts or facts" that are “causally connected to," or the “sine qua non” of the measures that Freeport challenges as breaches of the Stability Agreement and the TPA.81 That is not the standard set forth in Article 28 of the VCLT. Freeport's claims do not seek to bind Peru retroactively because they do not challenge measures that the Government adopted before the TPA entered into force.

(b) The U.S.'s recognition that Article 10.1.3 does not modify Article 28 of the VCLT is also consistent with the TPA negotiation record and the testimony of Mr. Herrera and Mr. Sampliner that the TPA parties did not intend "to bar claims simply because the challenged measures related to acts or facts that gave rise to a dispute before the TPA entered into force so long as the challenged measures themselves occurred after the entry into force."82 As Freeport explained, if the TPA parties intended Article 10.1.3 to apply broadly to bar pre-existing “disputes," as Peru argues,83 they would have adopted the non-retroactivity provision that the Andean States proposed in the July 2004 TPA draft, which stated that "this chapter shall only be applied to the disputes over facts and acts

that may arise after the entry into force of the Agreement."84 But they did not; instead they negotiated and agreed on the text of Article 10.1.3 in February 2005.85

23. Finally, the authorities that the U.S. cites support Freeport's argument that the non-retroactivity rule does not bar claims challenging post-entry-into-force measures that are sufficient to constitute a cause of action.

(a) Like Freeport,86 the U.S. concludes that the decision in Spence v. Costa Rica stands only for the limited proposition that claims must challenge post-entry-into-force conduct that is capable of constituting “an actionable breach in its own right.”87 The U.S. Submission therefore does not support Peru's reliance on Spence for the argument that the non-retroactivity rule bars all claims “based on" or "causally connected" to pre-entry- into-force acts or facts. As Freeport explained, each of the post-entry-into-force measures it challenges is capable of constituting an “actionable breach” of the Stability Agreement and the TPA "in its own right," irrespective of whether MINEM earlier expressed its novel position on the scope of stability guarantees in the non-binding June 2006 Report or any of the other reports and memoranda that Peru cites.88 Moreover, the U.S.'s discussion of Spence is consistent with Freeport's argument, recently confirmed by the Renco II v. Peru tribunal, that the reference to “deeply and inseparably rooted" conduct in the Spence decision does not "modify or supplement the applicable test," according to which the "allegedly wrongful conduct postdating the entry into force of the Treaty must ‘constitute an actionable breach in its own right.

Here, Freeport does not submit any claims challenging the failure to annul or redress the outcome of pre-entry-into-force measures. Instead, Freeport challenges measures that indisputably occurred after the TPA entered into force which independently gave rise to damages, not the failure to remedy those measures.

C. THE UNITED STATES' SUBMISSION SUPPORTS FREEPORT'S ARGUMENT THAT ARTICLE 22.3.1 DOES NOT APPLY TO PENALTIES AND INTEREST ON THE TAX ASSESSMENTS

24. Article 22.3.1, the TPA's tax exclusion, provides that “[e]xcept as set out in this Article, nothing in this Agreement shall apply to taxation measures.”96 As the U.S. Submission correctly observes, Article 1.3 of the TPA defines “measure" as "any law, regulation, procedure, requirement or practice.'"97 Thus, the U.S. Submission concludes that "[a]ny 'practice' related to ‘taxation' is therefore addressed by Article 22.3.1.98 Critically, the U.S. Submission clearly explains what it means for a “practice” to be related to taxation, stating that it “includes not only the application of, or failure to apply a tax, but also the enforcement or failure to enforce a tax.”99 It follows that any measure must apply or enforce a tax or fail to apply or enforce a tax to qualify as a taxation measure. Thus, the U.S. Submission supports Freeport's argument that Article 22.3.1 does not bar Freeport's Article 10.5 claims based on Peru's failure to waive penalties and interest on the Tax Assessments because the Parties agree that penalties and interest are not taxes in Peruvian law.100 It does not support Peru's attempt to expand Article 22.3.1 to cover “more than just ‘taxes.”'101

25. First, the U.S. Submission confirms Freeport's conclusion that Article 22.3.1 is limited to measures that apply or enforce a tax, but supplements it by including measures that fail to apply or enforce a tax. That supplementary observation is of no relevance here because Freeport does not challenge any measures failing to apply or enforce payment obligations. The U.S. Submission thus confirms that the term “measure" as defined in Article 1.3 does not expand the scope of Article 22.3.1 to encompass “more than just ‘taxes,”' as Peru argues.102 Rather, Article 1.3 merely clarifies that Article 22.3.1 applies irrespective of the type of measure the Government uses to impose a tax—be it a “law, regulation, procedure, requirement, or practice.”103 That conclusion is consistent with the “purpose” of

the tax exclusion, which “specifically is to preserve the States' sovereignty in relation to their power to impose taxes in their territory.”104

26. Second, the U.S. Submission is consistent with Freeport's argument that Peru's decisions failing to waive penalties and interest do not constitute taxation measures because they do not apply or enforce a tax. Peru and its experts “are in full agreement” with Freeport that “neither delinquent interest nor penalties are taxes."105 Moreover, Peru concedes that decisions of the Tax Tribunal and the Constitutional Court “define the term ‘tax”' and that Rule II of the “the Tax Code . . . appears to identify the types of 'taxes.”'106 Peru does not deny that those authorities clearly show that Peruvian law does not recognize penalties and interest as taxes and expressly excludes penalties from the definition of taxes.107

27. Third, the U.S.'s recognition that taxation measures must apply or enforce or fail to apply or enforce a tax contradicts each of Peru's attempts to expand Article 22.3.1.

(a) The U.S. Submission contradicts Peru's argument that the decisions failing to waive penalties and interest are “taxation measures” because “the disputed penalties and interest were imposed on SMCV as a direct result of its failure to comply with its underlying tax obligations."108 The U.S. Submission confirms that Article 22.3.1 does not apply to every Government act that may be the but-for consequence of a taxation measure. For example, SMCV made GEM payments as a consequence of the Government's

misrepresentation that, if SMCV paid GEM, SMCV would be exempt from SMT, which is a taxation measure.109 Yet, like the failure to reimburse GEM payments, which Peru does not contend is a taxation measure,110 penalties and interest measures do not qualify as taxation measures under the U.S.'s interpretation of Article 22.3.1.

(b) The U.S. Submission does not support Peru's argument that penalties and interest are taxation measures merely because they may incentivize payment of taxes.111 The U.S. Submission does not support the application of Article 22.3.1 to the broad and amorphous category of measures that may incentivize compliance with taxation measures; it only supports the application of Article 22.3.1 to measures that apply or enforce or fail to apply or enforce a tax. As Freeport explained, the means by which the Government enforces a tax is the coercive collection “procedure” for that tax.112 If the TPA parties intended Article 22.3.1 to apply more broadly to measures that apply or enforce non- taxes, such as penalties and interest, they would have used language to that effect, such as the term "fiscal measures."113

(c) The U.S. Submission does not support Peru's argument that any measure governed by the Tax Code or administered by the tax authorities constitutes a taxation measure.114 As Freeport explained, the fact that penalties and interest are identified as “components of tax debt," under Article 28 of the Tax Code is irrelevant.115 The term "tax debt"

encompasses a “broad range” of concepts that the Tax Code bundles together purely for purposes of procedural and administrative convenience because they are each administered by the Tax Administration and are subject to "similar procedures for their administration, payment, collection, and challenge," although they are not taxes.116 For example, Peruvian law classifies royalties and GEM as components of the “tax debt" and authorizes the same divisions of the MEF, SUNAT and the Tax Tribunal, to administer penalties and interest on tax assessments.117 Yet, Peru does not contend that royalty and GEM measures are taxation measures under the TPA.118 A measure that applies or enforces non-taxes cannot qualify as a taxation measure under the U.S.'s interpretation of Article 22.3.1 merely because it is governed by the tax code or administered by the tax authorities. Instead, the measure must itself apply or enforce or fail to apply or enforce a tax.

28. Finally, the U.S.'s interpretation of Article 22.3.1 is consistent with the cases interpreting tax exclusions in other treaties that Freeport cited.

(a) The tribunal in Nissan v. India concluded that "taxation measures” are “measures regulating the obligation to pay taxes."119 As the tribunal explained “not . . . every instance of governmental authority imposing monetary obligations . . . is . . . a 'tax”' and "the fact that a government ministry or department may impose fines or penalties as punishment for proscribed conduct . . . does not make these actions necessarily 'taxation

measures. . . ."120 Because penalties and interest are not taxes in Peruvian law, measures failing to waive penalties and interest cannot be measures “regulating the obligation to pay taxes."121

(b) The tribunal in Murphy v. Ecuador II concluded that payments to the Government must “constitute a tax" to be barred by the broader tax exclusion in the U.S.-Ecuador BIT, which applied to “matters of taxation.”122 In concluding that Ecuador's windfall levy on oil profits did not constitute a tax,123 the tribunal observed statements by government officials that the levy was not a tax,124 the “stated purpose of the law was to amend certain oil contracts held by certain oil companies,”125 and “[t]he revenue earned by the State under Law 42 was classified as non-tax revenue.”126 Similarly, in this case, the Tax Tribunal and the Constitutional Court have stated that penalties are not taxes and serve a distinct purpose from taxes,127 the Constitutional Court has stated that interest on tax assessments serve a distinct purpose from taxes,128 and penalties and interest are not recognized as taxes under the Peruvian Tax Code.129

(c) The tribunal in Antaris v. Czech Republic concluded that the Czech Republic's imposition of a "Solar Levy" was not a “taxation measure" because it did not “constitute” a tax in

Czech law,130 despite the ECT's broader language defining “taxation measures” as “any provision relating to taxes.”131 Moreover, the tribunal in Antaris expressly recognized that the fact the "Solar Levy [wa]s administered by the Tax Administration Law [wa]s not dispositive" because "[t]he 'definition' of tax contained in the Tax Administration Law extends to many payments which by their nature are not taxes.”132 Here, Rule II of the Peruvian Tax Code does not include penalties and interest as one of the types of taxes in Peruvian law.

D. THE UNITED STATES' SUBMISSION IS CONSISTENT WITH FREEPORT'S ARGUMENT THAT THE STABILITY AGREEMENT IS AN INVESTMENT AGREEMENT

29. As Freeport has explained, the Stability Agreement is an investment agreement under Article 10.28 of the TPA, upon which SMCV “reli[ed]” when “establish[ing] or acquir[ing]" the covered investment in the Concentrator.133 Thus, Freeport is entitled to submit breaches of the Stability Agreement under Article 10.16.1(b)(i)(C) of the TPA on behalf of SMCV.134

30. Article 10.16.1(b) of the TPA permits a claimant to bring claims for breach of an investment agreement on behalf of an enterprise the claimant owns or controls.135 Article 10.28 defines "investment agreement" as:

a written agreement between a national authority of a Party and a covered investment or an investor of another Party, on which the covered investment or the investor relies in establishing or acquiring a covered investment other than the written agreement itself.136

[Page 26]

31. Article 10.16.1, which incorporates the term “investment agreement" from Article 10.28, provides:

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

(C) an investment agreement;

(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

(C) an investment agreement;

provided that a claimant may submit pursuant to subparagraph (a)(i)(C) or (b)(1)(C) a claim for breach of an investment agreement only if the subject matter of the 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.137

32. The U.S. Submission, which focuses on the text of Article 10.16.1, is consistent with Freeport's argument that it is the text of Article 10.16.1 that controls.138 The U.S. Submission thus contradicts Peru's attempt to read into Article 10.16.1(b)(i)(C) an additional reliance requirement and a temporal limitation that are found nowhere in its text.

33. First, the U.S. Submission confirms that a claimant is only required to show: (i) that it relied on an investment agreement for claims under Article 10.16.1(a)(i)(C); or (ii) that the enterprise relied on an investment agreement for claims under Article 10.16.1(b)(i)(C).

(a) The U.S. Submission nowhere indicates that the reference to “investment agreement" in Article 10.16.1 deviates from the definition of “investment agreement" set forth in Article 10.28 of the TPA. It is thus inconsistent with Peru's argument that Article 10.28 "in no

138 See U.S. Submission ¶¶ 3-6; Reply and Counter-Memorial on Jurisdiction ¶¶ 282-86. ↩

[Page 27]

way dictates how the reliance should be read in a separate provision (Article 10.16.1).”139 Because Article 10.28 defines “investment agreement” “[f]or purposes of [] Chapter" Ten of the TPA, it necessarily dictates how the term “investment agreement” in Article 10.16.1 is understood.140

(b) Article 10.28 of the TPA states that “investment agreement means a written agreement between a national authority of a Party and a covered investment or an investor of another Party, on which the covered investment or the investor relies in establishing or acquiring a covered investment.”141 As Freeport explained, the reference to reliance in the Article 10.28 definition of “investment agreement" is clearly disjunctive—if the investor is the party to the agreement then the investor must have relied on the agreement or if an enterprise is the party to the agreement then the enterprise must have relied on the agreement.142 Thus, Freeport is entitled to bring Article 10.16.1(b)(i)(C) claims for breaches of the Stability Agreement on behalf of SMCV because SMCV relied on the Stability Agreement in establishing the “covered investment” in the Concentrator.

(c) The U.S.'s submission that [a]n investor may bring separate claims under both Articles 10.16.1(a) and 10.16.1(b)" but that the "relief available for each claim is limited to the article under which that particular claim falls" confirms that investment agreement claims brought by an investor and investment agreement claims brought on behalf of an enterprise are distinct.143 The U.S. Submission thus supports Freeport's argument that the only sensible reading of Article 10.16.1 is that a claimant must show either: (i) that the claimant relied on an investment agreement to bring claims for breach of that investment agreement under Article 10.16.1(a)(i)(C); or (ii) that the enterprise that it owns or controls relied on an investment agreement to bring claims for breach of that investment agreement on behalf of the enterprise under Article 10.16.1(b)(i)(C).144

(d) The U.S. agrees with Freeport that the “additional condition” that the final paragraph of Article 10.16.1 imposes is that “the subject matter of the claim and the claimed damages [must] 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.”145 The U.S. Submission refers to "additional condition" in the singular and thus does not support a further condition that the claimant rely on an investment agreement for Article 10.16.1(b)(i)(C) claims, which is found nowhere in Article 10.28.146

As Freeport explained, the 1994 U.S. Model BIT required only the reliance of the party to the investment agreement for a claimant to submit investment agreement claims and the U.S. did not intend to introduce an additional requirement when it updated the provision for investment agreement claims in Article 24.1(b)(i)(C) of the 2004 U.S. Model BIT, which is identical to Article 10.16.1(b)(i)(C).147 And as Mr. Herrera explained, he specifically sought "clarity" from the U.S. negotiating team about the reference to "reliance" in Article 10.16.1, leading to a clear understanding by both TPA parties "that for a given contract to qualify as an ‘investment agreement' under the TPA, an investor or a 'covered investment' had to rely on such contract in establishing or acquiring an investment.”148

34. Second, the U.S. Submission does not support the objection, that Peru raised for the first time in its Rejoinder and Reply on Jurisdiction, that there is a latent temporal limitation unique to

Article 10.16.1(b)(i)(C), which only permits investment agreement claims if the claimant or enterprise made the relevant investment in reliance on the investment agreement after the TPA's entry into force.149

(a) The U.S. Submission nowhere refers to a temporal limitation in Article 10.16.1(b)(i)(C), confirming that the definition of “covered investment" in Article 1.3, which includes investments established before the TPA entered into force, applies to Article 10.16.1(b)(i)(C).150

(b) Accordingly, the U.S. Submission is consistent with the negotiation history of the TPA. As Freeport explained,151 during the TPA negotiations, the U.S. sought to ensure that the investment agreement provisions of the TPA would apply to preexisting agreements that investors had established investments in reliance on, due to "special concerns" related to "recent litigation and cases derived from the actions of SUNAT.”152 Accordingly, the U.S. rejected an Andean proposal to limit the definition of investment agreements to agreements concluded two years after the Treaty entered into force.153 If the TPA parties intended to impose a temporal limitation on the investments that could be the subject of investment agreement claims, they would have done so expressly by adopting the Andean proposal or the language in other U.S. FTAs, including Article 15.1.14 of the U.S.- Singapore FTA, which expressly defines “investment agreement[s]" as those that “take effect on or after the date of entry into force of this Agreement.”154 They did not do so

and, as Mr. Sampliner and Mr. Herrera explain, that decision was intentional.155 By instead adopting Article 10.28, the TPA parties intended to allow preexisting contracts to become investment agreements after the TPA entered into force in the same way they intended to allow preexisting investments to become covered investments.

III. THE UNITED STATES' VIEWS ON THE MINIMUM STANDARD OF TREATMENT HAVE LIMITED RELEVANCE TO FREEPORT'S CLAIMS

35. The U.S.'s submissions on the means of establishing the content of the minimum standard of treatment and the obligations that the minimum standard comprises are of limited relevance to Freeport' claims. Freeport has established the obligations under the customary international law minimum standard of treatment relevant to the claims Freeport makes to the satisfaction of any burden of proof the U.S. Submission can reasonably be interpreted as supporting. Moreover, the U.S.'s submissions on "[c]laims for judicial measures” are irrelevant to Freeport's claims and the U.S. does not dispute the relevance of "legitimate expectations" and "transparency" in assessing breaches of the minimum standard.

A. FREEPORT HAS CARRIED ANY BURDEN OF PROOF FOR ESTABLISHING CUSTOM THAT THE U.S. SUBMISSION CAN REASONABLY BE INTERPRETED AS SUPPORTING

36. The U.S. opines that the claimant bears the burden of establishing the existence of an obligation under the customary international law minimum standard of treatment and advocates a narrow role for arbitration awards in ascertaining the content of the minimum standard.156 Yet, the authorities contradict both of these positions and the U.S. itself relies heavily on arbitration awards in asserting its views on the content of the minimum standard. Thus, the U.S.'s view on the means of establishing the content of the minimum standard ultimately has no bearing on Freeport's claims because Freeport has carried the burden of establishing the rules of customary international law relevant to the claims Freeport makes under the approach the U.S. takes in its own submission.

37. First, the conclusion by the U.S. that the concept of "burden of proof" applies to questions of law finds no support in the text of the TPA and is contradicted by authorities.157 International


(2004), Article 10.28). See also id. (citing CA-372, U.S.-Chile FTA (2003), Article 10.27 (defining “investment agreement” as those that "take effect at least two years after the date of entry into force").

[Page 31]

courts and tribunals have consistently recognized that the doctrine of jura novit curia applies to questions of law before an arbitral tribunal and thus the Tribunal is free to determine questions of customary international law based on the sources available to it.

(a) For example, in concluding that the concept of burden of proof does not apply to questions of customary international law, the International Court of Justice (the “ICJ") explained in the Fisheries Jurisdiction case that “the burden of establishing or proving rules of international law cannot be imposed upon any of the parties, for the law lies within the judicial knowledge of the Court.”158

(b) Investment treaty tribunals have consistently recognized the same principle.159 For example, the tribunal in Deutsche Telekom v. India explained, “[w]hen applying the governing law, be it international or national, the Tribunal is not bound by the arguments and sources invoked by the Parties. Under the maxim jura novit curia — or, better, jura novit arbiter — the Tribunal is required to apply the law of its own motion, provided it seeks the Parties' views."160

38. The U.S. does not engage with any of these authorities, and the authorities that it cites do not demonstrate that the claimant bears the burden of proof for establishing a rule of customary international law.

(a) The tribunal in Glamis Gold v. U.S.A. gives little reasoning for its conclusion that a claimant carries the burden for establishing rules of customary international law, cites no

authority for that proposition, is contrary to the weight of authority (see paragraph 37 above), and ignores the fundamental distinction between questions of law and fact.161

(b) The tribunal in Cargill v. Mexico acknowledged that its view that the claimant bore the burden of proving a change in customary international law was a departure from the view taken by various prior tribunals.162 The Cargill tribunal then looked to various arbitral decisions and other evidence to conclude that the minimum standard of treatment under customary international law had in fact substantially evolved beyond the antiquated standard followed in Glamis Gold.163

(c) The U.S. Submission also cites ADF Group v. U.S.A., Methanex v. U.S.A., and North Sea Continental Shelf—none of which decided the question of the burden of proof.164

(d) The U.S. cites the Lotus case, which concluded, without explanation, that France had not “conclusively proved" the rule of customary international law that France had “endeavoured to prove.”165 However, the decision pre-dates the ICJ's holding in the Fisheries Jurisdiction Case clearly establishing that the concept of the burden of proof does not apply to questions of customary international law by nearly half a century.166 Moreover, the PCIJ did not hold that conclusive proof by a party asserting a rule of

custom is necessary in all cases or explain why conclusive proof was necessary in that case.

(e) The U.S. also cites the Asylum Case and the Rights of Nationals case, which similarly predate the Fisheries Jurisdiction Case and, in any event, do not support the view that the claimant generally carries the burden of proof for questions of customary international law.167 The tribunal in Garcia Armas v. Venezuela, which recently affirmed the jura novit curia principle, explained that the Asylum Case and the Rights of Nationals only support the limited proposition that the claimant carries the burden for establishing local or regional custom.168

39. Second, the conclusion by the U.S. that only arbitral awards containing an examination of State practice and opinio juris are relevant to establishing a rule of customary international law is inconsistent with the authorities and the U.S.'s own reliance on arbitral awards in its submission.169

(a) As Freeport explained,170 “tribunals interpreting the minimum standard of treatment under NAFTA, CAFTA, and other treaties routinely rely on prior arbitral decisions, which do not contain surveys of State practice and opinion juris, as authoritative distillations of the customary international law standard."171 Moreover, the tribunals

consistently recognizing that a party may demonstrate the content of the minimum standard by relying on prior arbitral decisions nowhere suggest that those prior decisions must contain a survey of State practice and opinio juris to be instructive.172

(b) The U.S. Submission itself does not support the conclusion that arbitral decisions must examine State practice and opinio juris to be instructive on the content of customary international law. The U.S. relies almost exclusively on arbitral decisions that do not examine State practice or opinio juris to support its own views about the content of the minimum standard. For example, the U.S. defines denial of justice under the minimum standard of treatment by reference to prior arbitral decisions and relies on arbitral decisions to argue that legitimate expectations and transparency have not crystallized into "independent host State obligations” under the minimum standard.173

(c) The decisions that the U.S. relies on do not support the conclusion that arbitral decisions must examine State practice and opinio juris to be instructive on the content of customary international law. The Glamis decision nowhere draws that conclusion. Instead, the tribunal expressly recognized that arbitral decisions can “serve as illustrations of customary international law" and only concluded that arbitral decisions interpreting fair and equitable treatment treaty provisions are not instructive in establishing the content of

See also, e.g., RA-30, Glamis Gold Award, ¶ 605 ("Arbitral awards, Respondent rightly notes, do not constitute State practice and thus cannot create or prove customary international law.

the minimum standard.174 The U.S. also cites Obligation to Negotiate Access to the Pacific Ocean but in that case the ICJ merely concluded that investment treaty decisions on an investor's legitimate expectations were of no relevance to establishing a customary international law obligation arising from a State's legitimate expectations.175 The ICJ nowhere suggested that decisions addressing the question of whether there is a customary international law rule protecting an investor's legitimate expectations are irrelevant to tribunals in resolving that question.

40. Third, the conclusion by the U.S. that decisions by tribunals interpreting treaty-based fair and equitable treatment provisions are irrelevant to establishing the content of the minimum standard ignores the extensive assimilation of the two standards resulting from the minimum standard's evolution beyond its historical origins. As Freeport has explained, there is no longer any material difference between treaty-based and customary international law standards of “fair and equitable treatment.”176 Moreover, tribunals interpreting treaty-based fair and equitable treatment standards often expressly determine the content of the minimum standard of treatment and whether State conduct breached that standard, making them relevant even under the U.S.'s restrictive view.177


174 See RA-30, Glamis Gold Award, ¶ 605 (“Arbitral awards . . . can, however, serve as illustrations of customary international law if they involve an examination of customary international law, as opposed to a treaty-based, or autonomous, interpretation."). ↩

It does not follow from such references that there exists in general international law a principle that would give rise to an obligation on the basis of what could be considered a legitimate expectation. Bolivia's argument based on legitimate expectations thus cannot be sustained."). ↩

41. Finally, as reflected in Freeport's submissions and below, Freeport has established the obligations it asserts under the customary international law minimum standard of treatment by reference to more extensive authorities than the U.S. cites in its own submission.178 Thus, Freeport has carried any burden of proof that the U.S. Submission can reasonably be interpreted as supporting.

B. THE UNITED STATES' VIEWS ON THE CONTENT OF THE MINIMUM STANDARD OF TREATMENT ARE OF LIMITED RELEVANCE TO FREEPORT'S CLAIMS

42. The U.S.'s views on the content of the minimum standard of treatment are of limited relevance to Freeport's claims. The U.S. does not assess the evolution of “[c]laims for judicial measures” under the minimum standard of treatment and is therefore of limited assistance to the Tribunal in assessing Freeport's claims that Peru breached Article 10.5 when the contentious administrative courts arbitrarily and unreasonably refused to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2006-2007 and 2008 Royalty Assessments.179 Moreover, the U.S.'s opinion that the minimum standard of treatment does not contain independent "legitimate expectations" or "transparency" obligations does not contradict Freeport's argument that those concepts are relevant to assessing an alleged breach of the minimum standard.180

1. Challenges to Judicial Measures Under the Minimum Standard of Treatment Are Not Limited to Denial of Justice

43. The U.S. Submission concludes that “an investor's claim challenging judicial measures under Article 10.5.1 is limited to a claim for denial of justice under the customary international law minimum standard of treatment.”181 Yet, the U.S. Submission does not address the evolution in the minimum standard for judicial measures, which, like the content of the minimum standard as a whole, has


¶ 190 ("The Tribunal is of the opinion that in the instant case the Treaty standard is not different from that required under international law . . . [t]o this extent the Treaty standard can be equated with that under international law as evidenced by the opinions of the various tribunals cited above. It is also quite evident that the Respondent's treatment of the investment falls below such standards.")).

evolved from its “historical” origins.182 Accordingly, the U.S. Submission is ultimately of no assistance to the Tribunal on this point. In any event, nothing in the U.S. Submission suggests that due process challenges to administrative measures are limited to denial of justice. Thus, the U.S. Submission does not affect the merit of Freeport's claims that Peru breached Article 10.5: (i) when the Appellate Court notified SMCV of its decision arbitrarily and unreasonably refusing to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2006-2007 Royalty Assessments; (ii) when the Supreme Court notified SMCV of its decision arbitrarily and unreasonably refusing to consider de novo SMCV's entitlement to a waiver of penalties and interest on the 2008 Royalty Assessments; and (iii) when the Tax Tribunal violated SMCV's due process rights in the 2009, 2010-2011, Q4 2011, 2012, and 2013 Royalty Cases.183

44. First, Article 10.5 of the TPA does not suggest that challenges to judicial measures under the minimum standard are limited to denial of justice claims. Instead, as the U.S. correctly observes, Article 10.5.2 of the TPA sets forth a non-exhaustive list of obligations encompassed within the minimum standard of treatment, which is an “umbrella concept.”184 Annex 10-A adds that the TPA parties intended to incorporate “all” relevant customary international law principles that “protect the economic rights and interests of aliens” in the protections afforded by Article 10.5.185 Thus, Article 10.5.2 merely clarifies that the minimum standard of treatment “includes the obligation not to deny justice in . . . adjudicatory proceedings"—not that challenges to judicial measures under the minimum standard are limited to denial of justice.186


182 U.S. Submission ¶ 23 ("Denial of justice in its historical and 'customary sense' denotes 'misconduct or inaction of the judicial branch of the government' and involves 'some violation of rights in the administration of justice, or a wrong perpetrated by the abuse of judicial process."). But see RA-53, ADF Group Award, ¶ 179 ("[C]ustomary international law... is not 'frozen in time' and [] the minimum standard of treatment does evolve... both customary international law and the minimum standard of treatment of aliens it incorporates, are constantly in a process of development."). ↩

45. Second, as Freeport explained, the minimum standard for judicial measures has evolved from the standard applicable in claims of diplomatic protection of aliens in the early 20th century.187 Tribunals have recognized that challenges to judicial measures under the minimum standard are no longer limited to denial of justice. For example, the Eli Lilly tribunal observed that “the conduct of the judiciary will in principle be attributable to the State" like the conduct of any other state organ, and held that “a claimed breach of the customary international law minimum standard of treatment requirement of NAFTA Article 1105(1) may be properly a basis for a claim under NAFTA Article 1105 notwithstanding that it is not cast in denial of justice terms.”188 The U.S. Submission does not purport to examine this evolution and is thus of no assistance to the Tribunal on this point.

46. Given the evolution of the minimum standard of treatment, treaty-based and customary international law standards of "fair and equitable treatment" are now largely coextensive.189 Thus, investment treaty decisions concluding that treaty-based challenges to judicial measures are not limited to denial of justice claims confirm that the same is true of the minimum standard of treatment.190


187 See Reply and Counter-Memorial on Jurisdiction ¶ 134 ("Peru's argument that the 'full scope' of the minimum standard of treatment that states must provide to investors and their investments under customary international law remains the 1926 Neer tribunal's standard ... has been repeatedly rejected by tribunals and authorities interpreting the minimum standard of treatment."); CA-451, E. J. de Aréchaga, International Law in the Past Third of a Century, 159-1 Recueil des cours (General Course in Public International Law, The Hague, 1978) (31 December 1978) (former President of the ICJ recognizing that “in the present century State responsibility for acts of judicial organs came to be recognized. Although independent of the Government, the judiciary is not independent of the State: the judgment given by a judicial authority emanates from an organ of the State in just the same way as a law promulgated by the legislature or a decision taken by the executive” and that even in 1978, "denial of justice" was just one of the ways that "acts of judicial authorities" may result in "responsibility of the State"). ↩

188 CA-411, Eli Lilly v. Canada Final Award, ¶ 223 (“As a matter of principle, therefore, having regard to the content of the customary international law minimum standard of treatment, the Tribunal is unwilling to shut the door to the possibility that judicial conduct characterized other than as a denial of justice may engage a respondent's obligations under NAFTA Article 1105, within the standard articulated in the award in Glamis"). ↩

189 See, e.g., Reply and Counter-Memorial on Jurisdiction ¶ 134 ("[T]ribunals have consistently articulated the minimum standard of treatment under customary international law as protecting against state conduct that is arbitrary, non-transparent, involves a lack of due process, and/or is inconsistent with representations made by the state which were reasonably relied upon — in other words, that it is not materially different from the treaty- based fair and equitable treatment obligation."); Memorial ¶¶ 361-65 (“[T]he minimum standard of treatment's fair and equitable treatment obligation encompasses several interrelated obligations, including obligations (i) to honor the investor's legitimate expectations, (ii) of nonarbitrariness and reasonableness, (iii) to act with reasonable consistency and transparency, and (iv) to act with procedural propriety and due process."); id. ¶¶ 133, 137; Memorial ¶ 361 (citing CA-279, Murphy Partial Final Award, ¶ 208 (noting that "[t]he international minimum standard and the treaty standard continue to influence each other" and that "these standards are increasingly aligned”); CA-276, RDC Award, ¶ 218 (interpreting DR-CAFTA and adopting “the conclusion that the minimum standard of treatment is ‘constantly in a process of development") (quoting RA-53, ADF Group Award, ¶ 179). ↩

[Page 39]

47. Finally, the U.S. Submission provides no support for Peru's argument that a claimant is limited to challenging due process violations before administrative agencies like the Tax Tribunal as a denial of justice.191

(a) As Freeport explained, the denial of justice framework does not apply to the Tax Tribunal because, as Peru admits,192 the Tax Tribunal is not part of the judiciary, but rather is part of the executive branch, and acts as the final administrative decision-maker.193

(b) Investment treaty decisions confirm that the minimum standard of treatment does not require a claimant to frame due process challenges to administrative measures as a denial of justice. For example, the tribunal in TECO v. Guatemala applying the minimum standard of treatment provision in the DR-CAFTA concluded that “[t]he fact that the Claimant did not make the argument that there was a denial of justice in Guatemalan judicial proceedings cannot deprive the Arbitral Tribunal of its jurisdiction” because “the Claimant’s case was in fact not based on denial of justice before the Guatemalan courts, but primarily on the arbitrary conduct of the [Guatemalan energy agency] in establishing the tariff, as well as on an alleged lack of due process in the tariff review process.”194

Ukraine, PCA Case No. 2008-08, Award on the Merits (29 July 2014) (Vicuña, Brower, Lalonde), ¶ 405 (“The discussion about whether these various [judicial] decisions amounted to a denial of justice is immaterial because what this Tribunal has to determine in the end is whether they were manifestly unfair and unreasonable.”); CA-217, Dan Cake S.A. v.

[Page 40]

(c) In any event, the due process violations by the Tax Tribunal—including the interference by the Tax Tribunal President to dictate the results in the 2008 Royalty Case, the improper copy-pasting of the flawed resolution in that case to decide other cases, and the presence of a blatantly conflicted decision-maker presiding over the 2010-2011 Royalty Case—are exactly the type of conduct that prior tribunals have concluded constitute a denial of justice under the minimum standard of treatment.195

2. The United States' Submission Confirms That Deference to Domestic Court Decisions is Limited to the Denial of Justice Context

48. In its submission, the U.S. also opines that an international tribunal assessing “[c]laims for judicial measures” “will defer to domestic courts interpreting matters of domestic law unless there is a denial of justice.”196 For the reasons discussed in the preceding section, the U.S.’s opinion has no bearing on Freeport’s claims that Peru breached Article 10.5 when the contentious administrative courts arbitrarily and unreasonably refused to consider de novo SMCV’s entitlement to a waiver of penalties and interest on the 2006-2007 and 2008 Royalty Assessments.197 Moreover, the U.S. expresses its view in a section titled “[c]laims for judicial measures,” in a paragraph explaining that the allegedly “high threshold required for judicial measures to rise to the level of a denial of justice in customary international law gives due regard to the principle of judicial independence, the particular nature of judicial action, and the unique status of the judiciary in both international and municipal legal systems.”198 Thus, the U.S. opinion is clearly limited to the context of “[c]laims for judicial measures” and therefore has no relevance


195 See Reply and Counter-Memorial on Jurisdiction ¶ 163; CA-202, TECO Award, ¶¶ 458, 473, 682, 711 (finding administrative agency’s “willful disregard” of its own procedures and of “elementary standards of due process in administrative matters,” breached the fair and equitable treatment obligation, even though claimant did not allege a denial of justice claim); CA-237, Rumeli Award, ¶¶ 617-19 (finding breach of fair and equitable treatment obligation where administrative Working Group failed to provide “transparency and due process” “in contradiction with the requirements of the fair and equitable treatment principle,” by issuing a “summarily reasoned” decision, where the investor had no “real possibility” to present their claims, despite also concluding that there was no evidence of procedural or substantive error by courts). ↩

to Freeport’s remaining claims, none of which challenge judicial measures.199 Accordingly, the U.S. Submission is consistent with the investment treaty authorities Freeport cited showing that the decision of the Third Transitory Chamber of Constitutional and Social Law of the Supreme Court in the 2008 Royalty Case is entitled to no deference in resolving Freeport’s claims challenging non-judicial measures.200 Moreover, as Freeport explained, it would be particularly inappropriate for the Tribunal to defer to the Peruvian Supreme Court decision in resolving Freeport’s claims in the circumstances present here.201

49. First, domestic court decisions are entitled to no deference outside the denial of justice context. As Freeport explained, it is well-established that domestic court decisions have no binding effect in international investment treaty proceedings.202 A contrary result would undermine the contracting states’ agreement to submit disputes to an international forum independent of State courts.203


199 Freeport’s other Article 10.5 claims challenge (i) final and enforceable royalty assessments; (ii) final and enforceable penalty and interest assessments; and (iii) SUNAT’s decision denying SMCV’s request for reconsideration of its GEM reimbursement request, none of which are judicial measures. See Memorial ¶ 426 (“Peru violated Article 10.5 when the 2009, 2010-2011, Q4 2011, 2012, and 2013 Royalty Assessments became final and enforceable. . . Peru also violated Article 10.5 due to President Zoraida and Ms. Villanueva’s unlawful interference in the challenges to the 2006-2007 and 2008 Royalty Assessments” before the Tax Tribunal); ¶ 427 (“For all claims, except the 2006-07 and 2008 Royalty Assessments, Freeport has submitted claims based on the breaches that occurred when the Assessments of penalties and interest became final and enforceable and the administrative process concluded.”); ¶ 428 (“Peru breached Article 10.5 when it arbitrarily and unreasonably refused to reimburse SMCV’s GEM overpayments for Q4 2011 through Q3 2012. This breach occurred on 23 August 2019, the date that SUNAT’s decision denying SMCV’s request for reconsideration regarding the reimbursement request became a final administrative act.”). ↩

[Page 42]

50. Second, deferring to the Peruvian courts would be inconsistent with the dispute resolution scheme the TPA parties established in Chapter 10 of the TPA. Article 10.18.4 and Annex 10-G of the TPA,204 which are lex specialis in this case, define the only set of circumstances under which the existence of a prior domestic court proceeding may affect the Tribunal’s independent duty to hear and decide claims.205 Thus, the TPA parties explicitly intended for claims to be heard by an international tribunal if the claimant so elected, unless barred by Article 10.18.4 or Annex 10-G. As Freeport has explained, Article 10.18.4 does not apply here and it is undisputed that Annex 10-G is inapplicable.206 Thus, there is absolutely no basis for the Tribunal to abdicate its duty to independently assess Freeport’s claims by deferring to the Supreme Court decision in the 2008 Royalty Case.

51. Third, the authorities the U.S. cites do not indicate that an investment treaty tribunal resolving claims challenging non-judicial measures should defer to domestic court decisions on domestic law issues absent a denial of justice and, unlike Peru, the U.S. does not suggest otherwise.207 Those authorities only discuss the subject of deference in the context of adopting the antiquated view that a State will not be held internationally liable for judicial measures absent a denial of justice, which, as explained above in Section III.B.1 no longer prevails at customary international law. They do not support the view that an international tribunal should defer to domestic courts in resolving challenges to non-judicial measures and are therefore irrelevant to Freeport’s claims for breaches of the Stability Agreement and Article 10.5 of the TPA that do not challenge judicial measures.

(a) In Azinian v. Mexico, the tribunal rejected the argument that a local court decision annulling a concession contract constituted an expropriation, concluding that denial of justice provides the only “possibility of holding a State internationally liable for judicial decisions” and the claimants “d[id] not allege a denial of justice.”208

(b) The tribunal in Al Bahloul v. Tajikistan merely concluded that the claimant failed to prove the denial of justice challenge to a judicial decision that the claimant had expressly asserted.209

(c) In Apotex v. U.S.A., the tribunal resolved claims that various U.S. federal court decisions breached the NAFTA.210

(d) The Waste Management II tribunal resolved claims that court decisions constituted “a denial of justice”211

(e) Judge Tanaka’s separate opinion in Barcelona Traction addressed allegations that a “judgment of a municipal court” constituted a “denial of justice.”212

(f) The section of Jan Paulsson’s book “Denial of Justice in International Law” that the U.S. cites is limited to a discussion of the evolution of claims challenging judicial measures as a “substantive denial of justice” under international law.213

52. Fourth, as Freeport explained, the authorities that Peru cites similarly concern challenges to judicial measures.214 They do not suggest that international tribunals should defer to domestic courts outside of that context. Thus, they are likewise irrelevant to Freeport’s claims for breaches of the Stability Agreement and Article 10.5 of the TPA that do not challenge judicial measures.

53. Fifth, as Freeport explained,218 the Supreme Court’s decision in the 2008 Royalty Case is not even entitled to deference in Peruvian courts.219 For instance, in the subsequent 2006/07 Royalty Case, which involved the same parties and the same cause of action, the Supreme Court was unable to reach the four-vote majority required to issue a decision.220 Two of the five Supreme Court justices voted to annul and remand the decision for further analysis, a step that would have been unnecessary if the 2008 Royalty Case was entitled to deference.221

3. The United States' Submission is Consistent with Freeport's Argument That Legitimate Expectations and Transparency Are Relevant Under the Minimum Standard of Treatment

55. In its submission, the U.S. opines that an investor’s expectations about the “legal regime governing its investment . . . impose no obligations on the State under the minimum standard of treatment,” that the “concept[] of “legitimate expectations” does not give rise to an independent host State obligation, and that “something more” than frustration of an investor’s expectations is required to breach the minimum standard of treatment.233 The U.S. also opines that “transparency is not an independent source of obligation within the minimum standard of treatment.”234 Neither these opinions in the U.S. Submission,235 nor the decisions that the U.S. cites contradict Freeport’s argument that the frustration of the legitimate expectations of an investor and non-transparent conduct are relevant to the overall assessment of whether a State has breached the minimum standard of treatment,236 which is consistent with the weight of authority.237

IV. CONCLUSION

56. For the reasons discussed above, the U.S. Submission supports Freeport’s jurisdictional arguments and are of limited relevance to the merits of Freeport’s claims.

57. Freeport respectfully requests that the Tribunal dismiss Peru’s objections to jurisdiction, declare that it has jurisdiction over Freeport’s claims, and enter an award requiring Peru to pay compensation to Freeport as set forth in paragraph 319 of Freeport’s Reply and Counter-Memorial on Jurisdiction.

237 relevant to assessing whether the State has breached the fair and equitable treatment obligation.”). See also id. ¶ 140(b) (“Peru’s complete lack of transparency, in circumstances where the lack of transparency was misleading, is an important component of Peru’s unfair and inequitable conduct resulting in its breaches of Article 10.5”); id. ¶ 141 (A “volte-face followed by inconsistent and nontransparent conduct is exactly what prior tribunals have concluded gives rise to breaches of the fair and equitable treatment obligation”); Memorial ¶ 366 (“[W]hile each of these concepts presents a different dimension of the obligation of fair and equitable treatment that forms part of the minimum standard of treatment, it is not defined by a single definitive test: rather, the Tribunal’s task is to assess whether viewed comprehensively, the Government’s conduct violated the Treaty standard for each claimed breach.”). ↩

237 See, e.g., CA-285, Eco Oro Decision on Jurisdiction, Liability and Directions on Quantum, ¶ 754 (interpreting fair and equitable treatment under the MST and concluding that, “[r]eviewing past decisions, concepts such as transparency, stability and the protection of the investor's legitimate expectations play a central role in defining the FET standard.”) (emphasis added); CA-280, Windstream (I) Award, ¶¶ 379-80 (concluding that Canada’s failure to “bring clarity” and “address the legal and contractual limbo” imposed on the investor when the government adopted a moratorium on offshore wind development contributed to a breach of the minimum standard of treatment); CA-278, Bilcon/Clayton v. Canada Award, ¶ 455 (“The reasonable expectations of the investor are a factor to be taken into account in assessing whether the host state breached the international minimum standard of fair treatment under Article 1105 of NAFTA.”); RA-107, Cargill v. Mexico Award, ¶ 285 (concluding that a violation of the minimum standard of treatment “may arise in many forms” and “may relate to a lack of due process, discrimination, a lack of transparency, a denial of justice, or an unfair outcome”); RA-55, Mobil Investments Canada Inc. & Murphy Oil Corporation v. Canada, ICSID Case No. ARB(AF)/07/4, Decision on Liability and Principles of Quantum (22 May 2012) (van Houtte, Sands (partially dissenting), Janow), ¶ 152 (“[I]n determining whether [the MST] has been violated it will be a relevant factor if the treatment is made against the background of (i) clear and explicit representations made by or attributable to the NAFTA host State in order to induce the investment, and (ii) were, by reference to an objective standard, reasonably relied on by the investor, and (iii) were subsequently repudiated by the NAFTA host State.”); CA-269, Waste Management II Award, ¶ 98 (“In applying this standard it is relevant that the treatment is in breach of representations made by the host State which were reasonably relied on by the claimant.”). ↩
