[General aspects]

11.1. English and Spanish are the procedural languages of this annulment proceeding.

11.2. Routine, administrative, or procedural correspondence, including written requests addressed to, or sent by, the ICSID Secretariat shall be in English.

11.3. Each party is free to select which of the two procedural languages it will use in the oral parts of the proceeding, including the hearing and any meeting or conference call with the Committee. Simultaneous interpretation into the other language will be made available whenever necessary.

[For Committee's Documents]

11.4. The Committee may initially make any procedural order in one language and subsequently issue that procedural order in the other. Both language versions shall be equally authentic.

11.5. The Committee shall render its Decision on Annulment in English and Spanish simultaneously. Both language versions shall be equally authentic.

[For Parties' Pleadings]

11.6. Pleadings may be submitted in either procedural language, provided that a translation of any such pleadings to the other procedural language shall be filed within 14 calendar days thereafter.

11.7. Expert reports and witness statements (if any) shall be submitted in one procedural language, provided that a translation to the other procedural language is filed within 14 calendar days of the date of the original submission.

11.8. Legal authorities and fact exhibits introduced in the file pursuant to the procedure provided for in § 15.4 shall be submitted in either procedural language, without the need for translation into the other language. The parties shall be free, if they so desire, to submit courtesy translations into English or Spanish of any legal authorities.

[Page 10]

11.10. Documents filed in a language other than English or Spanish must be accompanied by a translation into one of these languages.

11.12. Translations need not be certified unless there is a dispute as to the translation provided and the party disputing the translation specifically requests a certified version.

[For Hearing]

11.14.

With respect to the examination of such a witness or expert, each examiner shall have the option of examining him or her in Spanish or English, with simultaneous translation from English to Spanish or Spanish to English, as the case may be. Transcripts of the whole hearing shall be taken in both languages.

11.15. The parties will notify the Committee as soon as possible, and no later than at the pre-hearing organizational meeting, in which language each witness or expert, if any, will give evidence.

11.16. The costs of interpretation will be paid from the advance payments made to ICSID, without prejudice to the decision of the Committee as to which party shall ultimately bear those costs.

13.1.2. Within two business days of the electronic filing pursuant to §13.1.1, upload the pleading, with all supporting documentation and updated index to the file sharing platform created by ICSID for purposes of this case.

The index shall follow the naming conventions contained in Annex A. Exhibits from the underlying arbitration shall maintain the exhibit number initially assigned to them. No new exhibit number should be assigned to such documents for purposes of the annulment proceeding.

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 determined by the Committee or the ICSID Secretariat, the parties shall upload to the file sharing platform created by ICSID for the purposes of this case an electronic copy of the entire case file.

of the Committee so requests, a USB drive containing an electronic copy of the entire file shall be delivered to such member at the addresses indicated below.

13.5. The addresses of the Committee Members are as follows:

Prof. Dário Moura Vicente

Guatemala City,
Guatemala
Mr. Antonio Hierro
Hernández-Mora
C/ Condes del Val 17A

Spain

13.6. The official date of receipt of a pleading or communication shall be the day on which the electronic file is sent to the Secretary of the Committee by email.

13.7. A filing shall be deemed timely if sent by a party by midnight, Washington, D.C. time, on the relevant date. If a filing falls on a Saturday or Sunday, the relevant date is the subsequent business day.

15.1. The Memorial and Counter-Memorial shall be accompanied by the supporting documents relied upon by the parties, including exhibits and legal authorities. Further supporting documents relied upon by the parties in rebuttal shall be submitted with the Reply and Rejoinder.

15.2. Neither party shall be permitted to submit additional or responsive documents after the filing of its last written submission, unless the Committee determines that special circumstances exist based on a timely and reasoned written application followed by observations from the other party.

[Page 13]

15.3. Given the nature of an annulment proceeding, the Committee expects that the parties will refer primarily to the evidentiary record from 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 evidence shall be admitted in this proceeding, unless the Committee determines that special circumstances exist based on a reasoned written request followed by observations from the other party. Such new evidence must concern the ICSID annulment proceeding, the interpretation of the ICSID Convention, or the legal standards governing the grounds of annulment invoked. Pleadings and correspondence submitted to the Tribunal in the underlying arbitration, as well as decisions issued by the Tribunal, are not new evidence and may be submitted as exhibits to submissions in this proceeding.

15.5. Documents shall be submitted in the manner and form set forth in §13.

15.6. Any documents introduced as exhibits or legal authorities in the annulment proceeding shall be labelled with numbers, and organized in a clear order:

15.6.1. Exhibits and legal authorities already included in the evidentiary record of the underlying arbitration proceeding shall be submitted in PDF format using the same numbering as in the arbitration proceeding (i.e., for the Claimant(s) “C-0001” for factual exhibits and “CL-0001" for legal authorities and for the Respondent “R-0001" for factual exhibits and “RL-0001" for legal authorities).

15.6.2. New exhibits admitted in accordance with §15.4 (if any) and legal authorities (if any) shall be numbered consecutively throughout the entire annulment proceeding and labelled according to the naming convention contained in Annex A.

15.6.3. 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 A.

15.6.4. The numbering shall also indicate the language of the document e.g. C-0001(ENG) for a document submitted only in English, C-0001(SPA) for a document submitted only in Spanish and C-0001(ENG/SPA) for a document submitted simultaneously in English and Spanish.

[Page 14]

15.6.5. Each exhibit shall have a divider with the exhibit identification number on the tab.

15.6.6. Electronic files and the accompanying indexes shall follow the naming conventions contained in Annex A.

15.7. 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.

15.8. 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.

15.9. The parties may use PowerPoint slides and demonstrative exhibits (such as charts, tabulations, etc. compiling information which is on record but not presented in such form), provided that they (i) identify the source in the record from which the information is derived, (ii) do not contain information not in the record.

15.10. An electronic copy of each demonstrative exhibit, other than PowerPoint slides, shall be distributed by the party intending to use it via an electronic mail sent to the entire case email distribution for each party, the Members of the Committee, the Secretary of the Committee, the court reporter, and to the interpreters as necessary 24 hours before its intended use. Electronic copies of PowerPoint presentations which are not by themselves demonstrative exhibits shall be provided via an electronic mail to each party, the Members of the Committee, the Secretary of the Committee, the court reporter, and to the interpreters just before their use.

15.11. In addition, promptly after the conclusion of the Hearing Day on which the corresponding demonstrative exhibit is used, the parties shall upload such demonstrative to the case folder in the BOX filesharing platform, designating each with the corresponding CD-___ or RD-___ number.

16. Witness Statements and Expert Reports
Convention Article 43(a); Arbitration Rule 24

16.1. When authorized by the Committee following the procedure outlined in §15.4, witness statements and expert reports shall be filed together with the parties' pleadings.

16.2. Each witness statement and expert report shall be signed and dated by the witness.

[Page 15]

17. Examination of Witnesses and Experts
Arbitration Rules 35 and 36

The production of such information may not be compelled from the Respondent, nor may such information be publicly disclosed, in accordance with §23 (Transparency), below.

23.6.1. For the Annulment Application, which pre-dates this order:

If Respondent objects to any of Applicants' redactions, the parties shall undertake their best efforts to resolve these objections. If the parties cannot resolve Respondent's objections within fourteen (14) calendar days and upon the request of either party, then the Committee will decide the issue.

23.6.2. For pleadings, memorials, and briefs:

Within fourteen (14) calendar days of the date of submission of the pleading, memorial, or brief, the respective party shall submit redacted versions that do not contain any “non-disclosure information". Within fourteen (14) calendar days of the date that the redacted versions are submitted to the Committee, the respective party shall notify the other party and the Committee whether it objects to any of the redactions. If the other party objects to any of the redactions, the parties shall undertake their best efforts to resolve these objections. If the parties cannot resolve the objections within fourteen (14) calendar days and upon the request of either party, then the Committee will decide the issue.

23.6.3. For minutes or transcripts of hearings and orders and decisions of the Committee:

The parties shall within twenty-one (21) calendar days of dispatch by the ICSID Secretariat submit redacted versions that do not contain any “non-disclosure information”. Within fourteen (14) calendar days of the date that the redacted versions are submitted to the Committee, each party shall notify the other party and the Committee whether it objects to any of the redactions. If there are objections, the parties shall undertake their best efforts to resolve these objections. If the parties cannot resolve the objections within fourteen (14) calendar days and on the request of either party, then the Committee will decide the issue.

23.6.4. For the Decision on Annulment:

The parties shall within 21 calendar days of dispatch by the ICSID Secretariat submit redacted versions of the Annulment Decision that do not contain any “non-disclosure information.” Within 21 calendar days of the date that the redacted versions are submitted to the Committee, each party shall notify the other party and the Committee whether it objects to any of the redactions. If there are objections, the parties shall undertake their best efforts to resolve these objections. If the parties cannot resolve the

objections within 14 calendar days and upon the request of either party, then the Committee will decide the issue.

To ensure that the former Members of the Committee can be compensated for the time spent deciding on any such disputes, ICSID will maintain the case trust fund open after the proceeding is concluded. The former Members of the Committee will be able to submit claims for such fees at the same hourly rate and through the same process used during the proceeding, and the claims will be paid from the advance payments made by the parties.

If the parties have not submitted any disputes regarding proposed redactions to the Decision on Annulment to the former Members of the Committee within 21 calendar days of the date on which the Decision on Annulment is dispatched, ICSID will proceed to close the case trust fund. If the parties do submit such disputes by this date, ICSID will close the case trust fund once the claims for fees and expenses relating to the resolution of disputes over redactions of the Decision on Annulment, if any, are received and paid.

23.7. Neither the parties nor the Committee shall disclose to the United States of America or to the public any “non-disclosure information” redacted in accordance with this Order or a subsequent ruling of the Committee.
