evidence: The European Court of Justice (ECJ), formally just the Court of Justice (French: Cour de Justice), is the supreme court of the European Union in matters of European Union law. As a part of the Court of Justice of the European Union, it is tasked with interpreting EU law and ensuring its uniform application across all EU member states under Article 263 of the Treaty of the Functioning of the European Union (TFEU).[2] [...] Notes [edit]- ^ Under the terms of the Protocol on Ireland/Northern Ireland, concluded as part of the Brexit withdrawal agreement, the CJEU — and hence the ECJ — continues to have jurisdiction over the operation of EU law applying to Northern Ireland in relation to customs and the movement of goods, technical regulations, VAT and excise, the Single Electricity Market and State aid, and may hear applications for preliminary rulings made by Northern Irish courts.[1] [...] The Protocol will also confer full jurisdiction on the CJEU to oversee the operation of EU law applying to Northern Ireland in relation to customs and the movement of goods, technical regulations, VAT and excise, the Single Electricity Market and State aid; including the jurisdiction to hear applications for preliminary rulings submitted by the courts of Northern Ireland. The UK will have the right to participate in these proceedings as if it were a Member State.
