1. INTRODUCTION
On March 21, 2022, Member States of the International Centre for
Settlement of Investment Disputes ("ICSID") approved a
comprehensive set of amendments to the ICSID's flagship rules
for resolving disputes between foreign investors and their host
States, after a five-year long process. This marks the fourth time
the ICSID rules have been updated. Also, this is the most extensive
review until now, as also explicitly acknowledged by the
ICSID.1 The amendments will come into effect on July 1,
2022 and will apply to arbitrations commenced from that date
onwards.
The amendment of the ICSID rules aim at modernising the rules
based on case experience, expediting proceedings, making the
process cost effective, enhancing the availability of alternative
dispute resolution, leveraging information technology to reduce the
environmental footprint of ICSID proceedings, increasing
transparency and addressing former deficiencies such as a lack of
guidance
