I read this in a CNN article:
The European Court of Justice sided with the advice of its top legal officer, who declared last week that the UK has the power to withdraw its notification to leave under Article 50 of the Lisbon Treaty, without the agreement of other member states.
If the UK is leaving, why does a European court decision matter? Why do any of the rules regarding how to leave matter? Sure it would be good on the global stage to follow all procedures, but in the end, they are leaving, right?
