On 7 December 2020, there was published on legislation.gov.uk The European Union Withdrawal (Consequential Modifications) (EU Exit) Regulations 2020 together with an explanatory memorandum. The purpose of the statutory instrument is to ensure that the UK statute book works coherently and effectively following the end of the transition period. It clarifies how certain terms, including EU-related definitions, should be interpreted in domestic legislation on or after the transition period (IP completion day). As part of this, the statutory instrument clarifies how cross references to EU legislation should be read. The statutory instrument also makes technical repeals to redundant provisions within primary legislation arising from the European Union (Withdrawal) Act 2018 (EUWA). These are primarily repeals of amending provisions, in particular relating to the European Communities Act 1972 (ECA 1972), where the EUWA has already provided for the repeal of the amended provisions. The purpose of the repeals is to tidy up the UK statute book and they have no substantive effect. The statutory instrument amends the Interpretation Act 1978 (and the devolved equivalents) in relation to the interpretation of references to “relevant separation agreement law”. The statutory instrument also amends the EUWA to provide for how existing references to EU instruments that form part of relevant separation agreement law and how existing non-ambulatory references to direct EU legislation should be read. It also makes consequential amendments to the European Union (Withdrawal) Act 2018 (Consequential Modifications and Repeals and Revocations) (EU Exit) Regulations 2019. The statutory instrument makes new interpretation provisions in light of the European Union (Withdrawal Agreement) Act 2020, to remove uncertainty about which version of an EU instrument applies, whether the retained version or the version applied by the Withdrawal Agreement. The statutory instrument provides a general gloss to ensure that the correct interpretation of the EU instrument applies.
