In December, the European Court of Justice ruled that the United Kingdom could unilaterally halt the Brexit process. The court stated that the UK had the power to withdraw its notification to leave the EU under Article 50 without the agreement of other member states. However, it must do so before the withdrawal agreement negotiated between the two parties comes into force, the court said. The case was brought before the ECJ by pro-Remain campaigners in Scotland, despite the British government’s opposition. After the ruling, Theresa May stated that she would not revoke Article 50 because it would betray voters who won the 2016 referendum.
