Question to the Cabinet Office:
To ask Her Majesty's Government what the role of the Court of Justice of the European Union will be in relation to Northern Ireland from 1 January 2021.
The rules that apply to businesses and citizens in Northern Ireland derive from UK law, including rules given effect by the EU (Withdrawal) Act 2018. The rules on how to interpret rules given effect by retained EU law, which the courts must follow, are set out in section 6 of the EU Withdrawal Act. Section 6 of the 2018 Act also sets out the role of the Court of Justice of the European Union.
