Overview of the Act
The European Union (Withdrawal) Act repeals the European Communities Act 1972 (ECA) on the day the United Kingdom leaves the European Union.
	The Act ends the supremacy of European Union (EU) law in UK law, converts EU law as it stands at the moment of exit into domestic law, and preserves laws made in the UK to implement EU obligations. It also creates temporary powers to make secondary legislation to enable corrections to be made to the laws that would otherwise no longer operate appropriately once the UK has left, so that the domestic legal system continues to function correctly outside the EU. The Act also enables domestic law to reflect the content of a withdrawal agreement under Article 50 of the Treaty on European Union once the UK leaves the EU, subject to the prior enactment of a statute by Parliament approving the final terms of withdrawal.
