During its 56th annual session in Vienna, Austria, the United Nations Commission on International Trade Law (UNCITRAL) adopted a Code of Conduct for Arbitrators in International Investment Disputes.1 The Code is the product of collaboration between the Secretariats of the International Centre for Settlement of Investment Disputes (ICSID) and UNCITRAL. It is intended to provide principles and provisions addressing matters such as arbitrator independence and impartiality and the duty to conduct proceedings with integrity, fairness, efficiency, and civility. The Code is based on a comparative review of standards found in codes of conduct in investment treaties, arbitration rules applicable to investor-state dispute settlement (ISDS), and international courts.2
In October 2023, UNCITRAL published an advance copy of the Code along with UNCITRAL’s decisions and comments titled “UNCITRAL Code of Conduct for Arbitrators in International Investment Dispute Resolution.”3 This advance copy defines “international investment dispute” as “a dispute between an investor and a State or a regional economic integration organization or any constituent subdivision of a State or agency of a State or a regional economic integration organization submitted for resolution pursuant to an instrument of consent.”4 This definition encompasses that which is commonly known as “investment treaty arbitration” and is contingent upon a combination of treaties protecting investments and investors, legislation governing foreign instruments, and investment contracts between a foreign investor and a State.5
The Code is applicable to arbitration proceedings by agreement of the disputing parties or as required in the instrument of consent to arbitral proceedings.6 Specifically, the Code calls for the independence and impartiality of arbitrators and imposes obligations not to be influenced by “loyalty to any disputing party or any other person or entity.”7 Additionally, the Code limits multiple roles in arbitration proceedings, or what is commonly called “double-hatting,” unless the disputing parties agree otherwise.8 These limitations prohibit an arbitrator from acting concurrently as a legal representative or an expert in any other proceeding involving the same measures, parties, related parties, or provisions.9 Furthermore, Article 5 of the Code imposes a duty of diligence on arbitrators, and Article 6, a duty of integrity and competence.10 The Code, moreover, prohibits ex parte communications in any case and requires complete confidentiality on behalf of an arbitrator, unless the disputing parties have agreed otherwise.11 Article 9, in turn, requires that arbitrators be compensated reasonably and in accordance with the instrument of consent or the applicable rules as chosen by the disputing parties, while Article 10 establishes the parameters under which an arbitrator may have an assistant.12 Finally, Article 11 requires an arbitrator to disclose “any circumstances likely to give rise to justifiable doubts as to his or her independence or impartiality,” and Article 12 requires general compliance with the Code while establishing that any challenge or disqualification of an arbitrator shall be governed by the instrument of consent or the applicable rules of the proceeding.13
Other types of alternative dispute resolution may choose to learn from and integrate those provisions that may be applicable to the nature of their proceedings. Arbitration, domestic, international, or otherwise, allows parties to choose the applicable rules under which to carry out their arbitral proceedings. In fact, Article 2 of the Code, regarding its application, establishes that “[t]he Code applies to an Arbitrator in, or a Candidate for, an [international investment dispute] proceeding, or a former Arbitrator. The Code may be applied in any other dispute resolution proceeding by agreement of the disputing parties.”14 Thus, the UNCITRAL Code of Conduct for Arbitrators in International Investment Dispute Resolution represents an avenue for the broad alternative dispute resolution community to carry out proceedings under a uniform code of conduct and eliminates the need for both institutional-specific or arbitration-specific rules to be created. The Code’s provisions remain relatively flexible, as most of the provisions are opted-in by agreement of the disputing parties. However, the decision to apply these rules to arbitration proceedings or otherwise ultimately falls on the disputing parties’ choice of arbitral institution (if any), the applicable rules, and the shared instrument of consent.
