These Regulations amend and revoke the EU legislation that governs the functioning of the institutions of the European Union. They are made in exercise of the powers conferred by section 8(1) of, and paragraph 21(b) of Schedule 7 to, the European Union (Withdrawal) Act 2018 (c.16) (“EUWA”) in order to address failures of retained EU law to operate effectively and other deficiencies (in particular under section 8(2)(a) and (b) and (3)(a)) arising from the withdrawal of the UK from the EU.
