Nearly five years after the end of the Brexit transition period, legacy EU law continues to occupy a substantial place in the UK legal system. Legislation enacted in 2023 was designed to reduce the scope and status of this body of domesticated EU law. Most of these measures were brought into force on 1 January 2024, but one major element of the reform – intended to encourage UK courts to depart from pre-Brexit EU case law – was not due to come into effect until 1 October 2024. But at the end of September, the new government quietly announced that commencement of the new rules would be postponed. In this In Practice article we examine the rules, how they would fit into the scheme of changes already in force and what we can expect now.
