The court hearing the action shall, in any event, apply Article 20 of this Convention;

(b) judgments given in a Contracting State by a court in the exercise of jurisdiction provided for in a convention on a particular matter shall be recognized and enforced in the other Contracting State in accordance with this Convention.
