Settlement of disputes l. At the time of deposit of its instrument of formal confirmation or of accession, or at any time thereafter, an international organization shall be free to choose, by means of a written declaration, one or more of the means for the settlement of disputes concerning the interpretation or application of this Convention, referred to in article ۲۸۷, paragraph ۱(a), (c) or (d).
۲. Part XV applies mutatis mutandis to any dispute between Parties to this Convention, one or more of which are international organizations.
۳. When an international organization and one or more of its member States are joint parties to a dispute, or parties in the same interest, the organization shall be deemed to have accepted the same procedures for the settlement of disputes as the member States; when, however, a member State has chosen only the International Court of Justice under article ۲۸۷, the organization and the member State concerned shall be deemed to have accepted arbitration in accordance with Annex VII, unless the parties to the dispute otherwise agree.
