Ruling No. 684 B+R3 (Cass.)

Abstract On July 25, 2025, the French Court of Cassation handed down an important decision concerning the existence in international law of possible exceptions to the functional immunity of agents of a foreign state. The Court of Cassation reached the conclusion that the “principle of functional immunity from jurisdiction in criminal matters” recognized for foreign agents acting in the exercise of their functions cannot be invoked in cases of prosecutions for genocide, crimes against humanity, and war crimes. However, the Court’s internationalist approach, which sought to identify the evolution of custom on the issue by examining relevant state practice, remains exclusively Eurocentric, by examining the practice of only five states, all from the same region of the world.
