On December 1, 2023, the International Court of Justice (ICJ) delivered a unanimous order on provisional measures in Arbitral Award of 3 October 1899 (Guyana v. Venezuela) (Provisional Measures Order). The ICJ indicated two provisional measures. It ordered first that, pending a final decision in the case, Venezuela shall refrain from taking any action that would modify the situation that currently prevails in the relevant disputed territory (the current situation being that Guyana administers and exercises control over the territory) and, second, that both states shall refrain from any action that might aggravate or extend the dispute before the ICJ.

On November 8, 2022, the Court of Justice of the European Union (CJEU) rendered a preliminary ruling in response to a request from the Administrative Court of Schleswig-Holstein, Germany. The request pertained to the interpretation of Article 9(3) of the Convention on Access to Information, Public Participation in Decision-Making and Access to Justice in Environmental Matters (Aarhus Convention). The CJEU held that Article 9(3) of the Aarhus Convention must be interpreted as precluding a situation where an environmental association is unable to challenge an administrative decision before a national court.
