Should European Union law automatically override national constitutions?

The principle of primacy establishes that EU law outweighs national law, including constitutions, ensuring that rights and regulations are identical across the bloc. This concept, developed by the European Court of Justice, has recently faced challenges from constitutional courts in countries like Poland and Germany. Proponents argue that without primacy, the EU legal order would disintegrate into conflicting national rules. Opponents argue that sovereignty resides in the nation-state and the EU cannot dictate fundamental constitutional values.
