When a question of interpretation of provisions of the Agreement, which are identical in substance to the provisions of the Treaties establishing the European Communities, as amended or supplemented, or of acts adopted in pursuance thereof, arises in a case pending before a court or tribunal of an EFTA State, the court or tribunal may, if it considers this necessary, ask the Court of Justice of the European Communities to decide on such a question.
An EFTA State which intends to make use of this Protocol shall notify the Depositary and the Court of Justice of the European Communities to what extent and according to what modalities the Protocol will apply to its courts and tribunals.
The Depositary shall notify the Contracting Parties of any notification under Article 2.
