The competent authority of a Contracting State may request the Court of Justice to give a ruling on a question of interpretation of the Convention or of one of the other instruments referred to in Article 1 if judgments given by courts of that State conflict with the interpretation given either by the Court of Justice or in a judgment of one of the courts of another Contracting State referred to in point 1 or 2 of Article 2. The provisions of this paragraph shall apply only to judgments which have become res judicata.

The interpretation given by the Court of Justice in response to such a request shall not affect the judgments which gave rise to the request for interpretation.

The Procurators-General of the Courts of Cassation of the Contracting States, or any other authority designated by a Contracting State, shall be entitled to request the Court of Justice for a ruling on interpretation in accordance with paragraph 1.

The Registrar of the Court of Justice shall give notice of the request to the Contracting States, to the Commission and to the Council of the European Communities; they shall then be entitled within two months of the notification to submit statements of case or written observations to the Court.

No fees shall be levied or any costs or expenses awarded in respect of the proceedings provided for in this Article.
