Article 13 Amendment of Certain Articles of the Protocol

Proposals for the amendment of Articles 10, 11, 12, and the present Article, may be initiated by any Contracting Party, or by the Director General. Such proposals shall be communicated by the Director General to the Contracting Parties at least six months in advance of their consideration by the Assembly.

Amendments to the Articles referred to in paragraph 1 shall be adopted by the Assembly. Adoption shall require three-fourths of the votes cast, provided that any amendment to Article 10, and to the present paragraph, shall require four-fifths of the votes cast.

Any amendment to the Articles referred to in paragraph 1 shall enter into force one month after written notifications of acceptance, effected in accordance with their respective constitutional processes, have been received by the Director General from three fourths of those States and intergovernmental organizations which, at the time the amendment was adopted, were members of the Assembly and had the right to vote on the amendment. Any amendment to the said Articles thus accepted shall bind all the States and intergovernmental organizations which are Contracting Parties at the time the amendment enters into force, or which become Contracting Parties at a subsequent date.
