Assimilation of retained EU law Abolition of Supremacy of EU law
The principle of the supremacy of EU law is a concept developed by the CJEU. The principle means that, where the domestic law of a Member State is found to be inconsistent with EU law, the latter takes priority.
	Under EUWA, this principle was incorporated into the UK statute book, so that the supremacy principle still applied in relation to domestic legislation that was made prior to the end of the Transition Period, after the UK’s exit from the EU. This ensured that domestic legislation related to EU obligations that remained in force after the UK left the EU continued to produce the same legal effects as before the UK’s departure. The principle does not apply to domestic legislation made after the end of the Transition Period.
	This Act abolishes the principle of supremacy of EU law in UK law at the end of 2023, so that it no longer applies in relation to any domestic legislation, whenever it was made.
