The 2022 Amendments of the Regulations and Rules of the International Centre for Settlement of Investment Disputes: Change and Continuity


This article examines the amendments of the Regulations and Rules of the International Centre for Settlement of Investment Disputes (ICSID) recently approved by the Administrative Council of ICSID. The amendments are of all regulations and rules for proceedings that ICSID has long been authorized to administer – ICSID Convention and Additional Facility conciliation and arbitration and fact-finding proceedings. As part of the amendments, ICSID has also issued a new set of mediation rules. For context, the article briefly recalls previous amendments of the Regulations and Rules before discussing highlights of the newly amended Regulations and Rules. A concluding section points out that the amendments, which respond to many criticisms of investor-State arbitration under investment treaties (ISDS), will generally apply to all ICSID ISDS arbitrations initiated on or after the effective date of the amendments (1 July 2022).
