European Communities Act 1972

The European Communities Act 1972 is a UK law that allowed the country to join the European Economic Community (EEC), which later became part of the European Union (EU). It made EU law supreme over UK law, meaning EU regulations and directives could take priority in legal matters. This act facilitated the integration of UK laws with EU policies, affecting various areas like trade, agriculture, and labor rights. It was a key legal framework until the UK left the EU in 2020, following which the Act was repealed, ending direct EU influence on UK law.
