1. A Regional Economic Integration Organization, which is constituted by sovereign States that have transferred competence over certain matters governed by this Protocol to that Organization, may sign, ratify, accept, approve or accede to this Protocol. A Regional Economic Integration Organization which is a Party to this Protocol shall have the rights and obligations of a State Party, to the extent that the Regional Economic Integration Organization has competence over matters governed by this Protocol.
2. Where a Regional Economic Integration Organization exercises its right of vote in matters over which it has competence, it shall have a number of votes equal to the number of its Member States which are Parties to this Protocol and which have transferred competence to it over the matter in question. A Regional Economic Integration Organization shall not exercise its right to vote if its Member States exercise theirs, and vice versa.
3. Where the number of States Parties is relevant in this Protocol, including but not limited to Articles 20 and 23 of this Protocol, the Regional Economic Integration Organization shall not count as a State Party in addition to its Member States which are States Parties.
4. At the time of signature, ratification, acceptance, approval or accession the Regional Economic Integration Organization shall make a declaration to the Secretary-General specifying the matters governed by this Protocol in respect of which competence has been transferred to that Organization by its Member States which are signatories or Parties to this Protocol and any other relevant restrictions as to the scope of that competence. The Regional Economic Integration Organization shall promptly notify the Secretary-General of any changes to the distribution of competence, including new transfers of competence, specified in the declaration under this paragraph. Any such declarations shall be made available by the Secretary-General pursuant to Article 24 of this Protocol.
5. States Parties which are Member States of a Regional Economic Integration Organization which is a Party to this Protocol shall be presumed to have competence over all matters governed by this Protocol in respect of which transfers of competence to the Organization have not been specifically declared or notified under paragraph 4.
