Artikel 31

1. Any Party may propose an amendment to this Convention. The text of any such amendment and the reasons therefor shall be communicated by that Party to the Secretary-General, who shall communicate it to the other Parties and shall ask them whether they accept the proposed amendment. If a proposed amendment so circulated has not been rejected by any Party within twenty-four months after it has been circulated, it shall be deemed to have been accepted and shall enter into force in respect of a Party ninety days after that Party had deposited with the Secretary-General an instrument expressing its consent to be bound by that amendment.
2. If a proposed amendment has been rejected by any Party, the Secretary-General shall consult with the Parties and, if a majority so requests, he shall bring the matter, together with any comments made by the Parties, before the Council which may decide to call a conference in accordance with Article 62, paragraph 4, of the Charter of the United Nations. Any amendment resulting from such a Conference shall be embodied in a Protocol of Amendment. Consent to be bound by such a Protocol shall be required to be expressed specifically to the Secretary-General.
