Quoting somebody else, this is what happens when laws are written by diplomats instead of lawyers.I feel that this ruling only makes leaving the EU more difficult for other member states. What's the point in the EU even negotiating a withdrawal agreement if the notification can be withdrawn unilaterally?
If A50 is non binding from one side it just becomes meaningless right?
This is also why the EU is being rah-rah-rah about laws and regulations and why it'll only become much more stringent about them. The EU is a creature of laws, so bad stuff happens whenever it forgets about that.
