Section 1: Repeal of the European Communities Act 1972
Section 1 repeals the ECA on exit day. As set out above, this Act is the principal piece of domestic legislation passed by the UK Parliament which gives effect to EU law in the UK and gives EU law supremacy over UK domestic law. The main effects of repealing the Act are to reflect the end of supremacy of EU law in domestic law and to remove the mechanism which enabled the flow of new EU law into UK law.
