European Court of Justice and UK Law
The European Court of Justice (ECJ) is the highest court in the European Union concerning EU law. Before Brexit, its rulings were binding on the UK, shaping areas such as trade, competition, and human rights. Following Brexit, the UK is no longer under direct ECJ jurisdiction, but the court’s decisions may still influence UK law, especially regarding Northern Ireland and agreements involving the EU.

❓ Frequently Asked Questions
What is the European Court of Justice (ECJ) and what does it do?
The ECJ is the EU's top court for interpreting and enforcing EU law. It ensures uniform application across member states, settles disputes involving EU institutions or member states, and can issue preliminary rulings when national courts seek guidance on EU law.
Does the ECJ still rule on UK law after Brexit?
Not in general. The UK is no longer bound by EU law, so ECJ judgments do not typically bind UK domestic courts. An exception is in Northern Ireland, where EU law continues to apply in some areas under the Protocol, and UK law may still involve retained EU law interpreted with EU rules in mind.
What is a preliminary reference to the ECJ?
A national court asks the ECJ to interpret a point of EU law. The ECJ’s ruling clarifies the law for that case and helps ensure consistent interpretation across the EU; the decision is binding on the referring court.
What is retained EU law and how does it relate to the ECJ?
Retained EU law is EU-derived law kept in UK law after Brexit. It remains enforceable in the UK and is interpreted by UK courts; ECJ influence remains for EU-law matters that still apply in areas like Northern Ireland, but the ECJ does not directly govern UK domestic law.
