Suspension of proceedings
If a competent court of a Member State has information that processing proceedings concerning the same matter and the same controller or processor are pending before a court of another Member State, it shall contact that court in the other Member State to verify the existence of such proceedings.
If proceedings concerning processing relating to the same matter and the same controller or processor are pending before a court of another Member State, any court with jurisdiction other than the court first seized may stay its proceedings.
If those proceedings are pending at first instance, any court not first seized may also make a reference at the request of one of the parties, provided that the court first seized has jurisdiction to hear both proceedings and its law permits joinder.
