The regulation of organic products, and of genetically modified organisms, is based on EU law. The European Union (Withdrawal) Act 2018 brings this EU law into UK statute, so that it will continue to have effect after the end of the transition period. Amendments since have ensured that the retained law refers to the UK system, not the EU. However, under the Northern Ireland Protocol, Northern Ireland will remain subject to the EU’s laws. This article looks at two statutory instruments that further amend the 2019 regulations so that they refer only to Great Britain, enabling Northern Ireland to continue to meet EU law.
