What is the European Communities Act?

The European Communities Act (1972) is the domestic legislation that took the UK into what was then the European Economic Community, a precursor to the EU, following the signing of a treaty on 22 January 1972. This legislation became the basis upon which all European Union law flowed into the UK while a member state. In June 2018, the UK parliament passed the European Union (Withdrawal) Act 2018, which will repeal the European Communities Act on exit day from the EU, as well as copying over existing EU law into UK law to maintain legal stability.
