On January 18, 2019, the International Centre for Settlement of Investment Disputes (ICSID) released a compendium of state and public comments [3] on proposed amendments to ICSID’s procedural rules. The compendium includes all comments sent by states and public stakeholders on the proposed amendments prior to January 15, 2019, and they address the proposals made in the working paper [4] ICSID released on August 3, 2018. The aim of the proposed amendments is “to further modernize, simplify, and streamline the ICSID rules for arbitration, conciliation, mediation and fact-finding,” and they address issues such as  “transparency, appointment and disqualification of arbitrators, security for costs, allocation of costs, consolidation of cases, and third-party funding.” The press release [5] states that the “ICSID Secretariat is now in the process of updating the amendments based on these comments and will publish a further revised working paper in the spring of 2019.”
