Notes:
At least as of 2010 amendments, EIF of amendments were tacit and took effect immediately, per Article 9.8: "9.8 An amendment shall be incorporated in this Arrangement and shall have effect immediately after the Annual Meeting that approves the amendment or in the case where one or more Parties are not present at the Annual Meeting or at a Special Meeting of the Parties, thirty days following the date upon which the Party or Parties have notified the depositary of their acceptance of the proposed amendment." https://pnatuna.com/index.php/implementing-arrangements
