Given the agreements reached by the Parties on all procedural issues, and with the agreement of the Parties, the first session of the ad hoc Committee (“Committee”) was held solely with the Members of the Committee and by correspondence. .
On 5 August 2025, following consultation with the Parties, the Committee informed the Parties that the First Session would be held by videoconference on 15 September 2025.
On 13 August 2025, the Committee provided a draft Procedural Order No. 1 which was intended to facilitate the parties’ discussions on procedural matters and serve as the agenda for the First Session of the Committee. The Committee invited the Parties to confer concerning the items addressed in the draft order, to modify the contents as they saw fit and to submit a joint proposal advising the Committee of: (i) the Parties’ agreements on procedural matters, (ii) the Parties’ respective positions regarding any items on which they did not agree, and (iii) any additional matters that the Parties would like to discuss during the First Session.
On 26 August 2025, the Parties submitted a joint proposal of the draft Procedural Order No. 1, which reflected the Parties’ agreements on procedural matters and indicated the following:
The Parties are pleased to report that they have reached agreement on all of the issues set out in the attached draft.
Given that there are no issues in dispute between the Parties for the Committee to address, the Parties would be amenable to the First Session being held solely among the members of the Committee based on the Parties' written proposals. The Parties would be grateful if the Committee could indicate by 10 September 2025 whether it prefers to hold the First Session with or without the Parties.
On 31 August 2025, the Committee invited the Parties to further comment on additional suggestions added to the draft Procedural Order No. 1.
On 4 September 2025, the Parties submitted their comments to the Committee’s additional suggestions.
On 5 September 2025, the Committee informed the Parties that, in light of the Parties’ agreements, the date for the First Session was vacated. The Committee held a First Session on 5 September 2025 by correspondence among its Members. The Committee considered the following:

13.2. Electronic files of pleadings, witness statements and expert reports (if any), exhibits and legal authorities shall be text searchable (i.e., OCR PDF or Word).
13.3. All pleadings shall be accompanied by a consolidated and updated index to all the supporting documentation that the Party has submitted up to the date of the pleading. The index shall indicate the document number, the pleading with which it was submitted and the language of the document. The index shall use the naming conventions in Annex D, and it shall follow the templates in Annex B and C.
13.4. At the conclusion of the written phase of the proceeding, on a date to be determined by the Committee, or at any other time the Committee or the Secretariat so requests, the parties shall courier to the ICSID Secretariat at the address indicated at § 7.2 supra and to each Member of the Committee at the addresses indicated at § 2.2 supra a USB drive (PC and Mac compatible) containing an electronic copy of the entire annulment proceeding file (including pleadings, witness statements, expert reports, exhibits, legal authorities and Committee decisions and orders to date) with a consolidated hyperlinked index of all documents (the “Electronic Hearing Bundle”).

Further supporting documents relied upon by the Parties in rebuttal shall be submitted with the Reply on Annulment and Rejoinder on Annulment.
15.2. Neither Party shall be permitted to submit additional or responsive documents after the filing of its respective last written submission, unless the Committee determines that special circumstances exist based on a timely and reasonable written request followed by observations from the other Party. Such submission may not be made prior to the Committee’s determination.
15.3. Given the nature of an annulment proceeding, the Committee expects that the Parties will refer primarily to the evidentiary record of the arbitration proceeding, and it does not expect to receive new evidence (exhibits, witness statements or expert reports).
15.4. Therefore, without prejudice to each Party’s right to submit new legal authorities, no new factual and/or witness or expert evidence shall be admitted in this proceeding, unless the Committee determines that special circumstances exist based on a reasonable timely written request followed by observations from the other Party. Should a Party submit such a written request, that Party may not annex the new evidence that it seeks to file to the request until a decision is taken by the Committee. The requesting Party shall not quote such evidence in its request, but shall be allowed to provide sufficient context for the Committee to assess the relevance and materiality of the document.
15.5. For the avoidance of doubt, if the Committee decides to procedurally admit into the record any such new evidence, this shall be strictly limited to the ICSID annulment process, interpretation of the ICSID Convention, and/or the invoked grounds for annulment, and the other Party will be granted the opportunity to submit equivalent evidence in rebuttal within a reasonable period of time to be determined by the Committee.
15.6. If the Committee grants the request for the submission of new evidence, it shall ensure that the opposing Party is (i) given a sufficient opportunity to present its observations on the document and (ii) permitted to submit rebuttal evidence.
15.7. Any documents introduced as exhibits or legal authorities in this annulment proceeding shall be numbered and organized in the following manner:
15.8. Exhibits and legal authorities in this annulment proceeding shall be submitted in PDF format and numbered using the same conventions used in the original arbitration proceeding (regardless of which of the Parties is the Applicant in the present

15.9. Exhibits and legal authorities already included in the evidentiary record of the original arbitration proceeding shall be identified and referred to using the same number as in the original arbitration proceeding. The parties shall include with their submissions in this annulment proceeding any material from the original arbitration proceeding that they wish to rely on.
15.10. New exhibits admitted in accordance with § 15.4 supra (if any), and new legal authorities shall be numbered consecutively throughout the entire annulment proceeding, starting from the last number used in the original arbitration proceeding, i.e., beginning with C-209 and CL-188 for South32; and beginning with R-97 and RL-133 for Colombia. For the sake of clarity, documents from the original arbitration which were not originally numbered (i.e., correspondence, pleadings, procedural orders) will be given a new consecutive exhibit number by the party submitting them.
15.11. Any witness statements or expert reports from the underlying arbitration proceeding which are submitted in the annulment proceeding, as well as any new witness statements or expert reports admitted in accordance with § 15.4, shall be labelled according to the naming convention contained in Annex D.

The numbering of the PDF files shall also indicate the language of the document, e.g. C-000X-ENG for a document submitted only in English, C-000X-SPA for a document submitted only in Spanish and C-000X-SPA/ENG for a document submitted simultaneously in the same PDF file in Spanish original with an English translation.
15.13. The number of the exhibit or legal authority shall appear on the first page of the document, and shall be used in the electronic file name.
15.14. Electronic files shall follow the naming conventions contained in Annex D. Indexes shall follow the templates in Annex B and Annex C.
15.15. Copies of documentary evidence shall be assumed to be authentic unless specifically objected to by a Party, in which case the Committee will determine whether authentication is necessary.
15.16. The Parties shall file all documents only once by submitting them with their pleadings. Documents need not be resubmitted with witness statements or expert reports even if referred to in such statements.
15.17. Demonstrative exhibits (such as PowerPoint slides, charts, tabulations, etc. compiling information which is on record but not presented in such form) may be used at any hearing, provided that they: (i) identify the source on the record from
[Page 12]
which the information is derived; and (ii) do not contain information that is not on the record. Each Party shall number its demonstrative exhibits consecutively (preceded by “CD-” for South32 and preceded by “RD-” for Colombia).
15.18. The Party submitting such demonstrative exhibits shall provide them in electronic format and, if requested, in hard copy to the other Party, the Members of the Committee, the Secretary of the Committee, the court reporter(s) and the interpreter(s), at the hearing at a time to be decided at the pre-hearing organizational meeting. In addition, promptly after the conclusion of the hearing day in which the corresponding demonstrative exhibit is used, the submitting Party shall upload such demonstrative to the case folder in the electronic file-sharing platform (Box), designating each with the corresponding CD-__ or RD-__ number.
