On May 21, 2023, the International Court of Justice (ICJ) in The Hague delivered a landmark advisory opinion affirming that the right to strike is protected under a key labour treaty. This opinion was sought by the International Labour Organisation (ILO) to resolve a dispute regarding the treaty's implications for workers' rights. While advisory opinions from the ICJ are not legally binding, they carry significant influence and could shape labour regulations globally. The treaty in question has been ratified by 158 countries and is integrated into various international frameworks, including those of the Organisation for Economic Cooperation and Development and international trade agreements. Notably, the United States, a member of the ILO, has not ratified this convention. The ICJ's ruling comes after hearings in October 2022, where representatives from 18 countries and five international organisations expressed support for the right to strike. This decision follows the court's previous advisory opinion that indicated countries could be in violation of international law if they neglect to protect the environment from climate change, underscoring the court's role in addressing significant global issues.
