I’m supporting the attempt to mount a legal case in the Dutch courts to protect the fundamental status of EU citizens who happen to be British. The detailed legal argument is given in this article, which cites the ECJ’s view that “citizenship of the Union is intended to be the fundamental status of nationals of the Member States. ”
The substance of the crowdfunded case is based on a similar argument to the one I’ve made in my petition to the EU Parliament, which is still active. If EU citizenship is a fundamental right, it can’t be taken away. Do please support the petition, even if you can’t pledge to support the legal case.
