"1. Where proceedings involving the same cause of action and between the same parties are brought in the courts of different Member States, any court other than the court first seised shall of its own motion stay its proceedings until such time as the jurisdiction of the court first seised is established. 2. Where the jurisdiction of the court first seised is established, any court other than the court first seised shall decline jurisdiction in favour of that court."
"1. Where related actions are pending in the courts of different Member States, any court other than the first court first seised may stay its proceedings. 2. Where these actions are pending at first instance, any court other than the court first seised may also, on the application of one of the parties, decline jurisdiction if the court first seised has jurisdiction over the actions in question and its law permits the consolidation thereof. 3. For the purposes of this Article, actions are deemed to be related where they are so closely connected that it is expedient to hear and determine them together to avoid the risk of irreconcilable judgments resulting from separate proceedings."
