On the 21 October 2019 the International Court of Justice (ICJ) adopted amendments to Articles 22, 23, 29, 76 and 79 of its Rules of Court (entry into force 21 October 2019). Of particular interest is the amendment to Article 76(1) to “clarify” the Court has the power to revoke or modify provisional measures on its own initiative:
1. At the request of a party or proprio motu, the Court may, at any time before the final judgment in the case, revoke or modify any decision concerning provisional measures if, in its opinion, some change in the situation justifies such revocation or modification.
The ICJ may, for example, prescribe provisional measures in a case submitted to it by way of Articles 287 and 290 of UNCLOS. For an example of previous requests on the basis of Article 41 of the ICJ Statute and (former) Article 76 of the Rules of Court see the submissions of both Costa Rica and Nicaragua in Certain Activities Carried Out by Nicaragua in the Border Area (Costa Rica v. Nicaragua); Construction of a Road in Costa Rica along the San Juan River (Nicaragua v. Costa Rica), Order of 16 July 2013, Provisional Measures, I.C.J. Reports 2013, p. 230.
