Article 26

A State Party may propose an amendment to this Convention. The proposed amendment shall be submitted to the depositary, who circulates it immediately to all States Parties.

If the majority of the States Parties request the depositary to convene a conference to consider the proposed amendments, the depositary shall invite all States Parties to attend such a conference to begin no sooner than three months after the invitations are issued.

The conference shall make every effort to ensure amendments are adopted by consensus. Should this not be possible, amendments shall be adopted by a twothirds majority of all States Parties. Any amendment adopted at the conference shall be promptly circulated by the depositary to all States Parties.

The amendment adopted pursuant to paragraph 3 of the present article shall enter into force for each State Party that deposits its instrument of ratification, acceptance, accession or approval of the amendment on the thirtieth day after the date on which two thirds of the States Parties have deposited their relevant instrument. Thereafter, the amendment shall enter into force for any State Party on the thirtieth day after the date on which that State deposits its relevant instrument.
