Article 28 Revision of the Appendix

In order to update the list of treaties in the Appendix, amendments may be proposed by any Party or by the Committee of Ministers. These proposals for amendment shall only concern universal treaties concluded within the United Nations system dealing specifically with international terrorism and having entered into force. They shall be communicated by the Secretary General of the Council of Europe to the Parties.

After having consulted the non-member Parties, the Committee of Ministers may adopt a proposed amendment by the majority provided for in Article 20.d of the Statute of the Council of Europe. The amendment shall enter into force following the expiry of a period of one year after the date on which it has been forwarded to the Parties. During this period, any Party may notify the Secretary General of the Council of Europe of any objection to the entry into force of the amendment in respect of that Party.

If one third of the Parties notifies the Secretary General of the Council of Europe of an objection to the entry into force of the amendment, the amendment shall not enter into force.

If less than one third of the Parties notifies an objection, the amendment shall enter into force for those Parties which have not notified an objection.

Once an amendment has entered into force in accordance with paragraph 2 and a Party has notified an objection to it, this amendment shall come into force in respect of the Party concerned on the first day of the month following the date on which it notifies the Secretary General of the Council of Europe of its acceptance.
