The International Centre for Settlement of Investment Disputes (ICSID) adopted amendments to its rules on 21 March 2022. They are set to come into force on 1 July 2022 and will apply to proceedings commenced after that date. The amendments are the culmination of a consultative process that was launched in 2016, comprised six working papers, and involved extensive consultations with ICSID Member States and stakeholders.1

With its amended rules, ICSID aims to "modernize, simplify, and streamline the rules, while also leveraging information technology to reduce the environmental footprint of ICSID proceedings."2 In addition to amending the Regulations and Rules for ICSID Convention Proceedings - including the Administrative and Financial Regulations, Institution Rules, Arbitration Rules, and Conciliation Rules - as well as the ICSID Additional Facility Rules, entirely new procedural rules for mediation and fact-finding have been introduced.

In this article, the most notable amendments to the Regulations and Rules for ICSID Convention Proceedings and the ICSID Additional Facility Rules are introduced.
