La place de la coutume internationale en droit public français

Abstract

Abstract Bernard Stirn’s presentation examines the status of international custom in French public law. He notes that international custom may be considered as covered by the reference in the preamble of the Constitution to the rules of public international law. He underlines the increased effects of international custom in the French domestic legal order as enshrined in the latest developments of the case-law of the Conseil d’Etat. He stresses that whilst French administrative judges may set aside a law in the event of a conflict with the provisions of an international treaty, they do not possess a similar power in the case of a conflict with a rule of customary international law. He concludes by citing cases in which the French constitutional court has made reference to international custom.
