1. This Convention shall not affect any conventions by which the Contracting Parties and/or the States bound by this Convention are bound and which in relation to particular matters, govern jurisdiction or the recognition or enforcement of judgments. Without prejudice to obligations resulting from other agreements between certain Contracting Parties, this Convention shall not prevent Contracting Parties from entering into such conventions.

2. This Convention shall not prevent a court of a State bound by this Convention and by a convention on a particular matter from assuming jurisdiction in accordance with that convention, even where the defendant is domiciled in another State bound by this Convention which is not a party to that convention. The court hearing the action shall, in any event, apply Article 26 of this Convention.

3. Judgments given in a State bound by this Convention by a court in the exercise of jurisdiction provided for in a convention on a particular matter shall be recognised and enforced in the other States bound by this Convention in accordance with Title III of this Convention.

4. In addition to the grounds provided for in Title III, recognition or enforcement may be refused if the State addressed is not bound by the convention on a particular matter and the person against whom recognition or enforcement is sought is domiciled in that State, or, if the State addressed is a Member State of the European Community and in respect of conventions which would have to be concluded by the European Community, in any of its Member States, unless the judgment may otherwise be recognised or enforced under any rule of law in the State addressed.

5. Where a convention on a particular matter to which both the State of origin and the State addressed are parties lays down conditions for the recognition or enforcement of judgments, those conditions shall apply. In any event, the provisions of this Convention which concern the procedures for recognition and enforcement of judgments may be applied.
