Artikel 17

(1). Proposals for the amendment of this Convention may be initiated by any Member State, by the Coordination Committee, or by the Director General. Such proposals shall be communicated by the Director General to the Member States at least six months in advance of their consideration by the Conference.
(2). Amendments shall be adopted by the Conference. Whenever amendments would affect the rights and obligations of States party to this Convention not members of any of the Unions, such States shall also vote. On all other amendments proposed, only States party to this Convention members of any Union shall vote. Amendments shall be adopted by a simple majority of the votes cast, provided that the Conference shall vote only on such proposals for amendments as have previously been adopted by the Assembly of the Paris Union and the Assembly of the Berne Union according to the rules applicable in each of them regarding the adoption of amendments to the administrative provisions of their respective Conventions.
(3). Any amendment 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 the States Members of the Organization, entitled to vote on the proposal for amendment pursuant to paragraph (2), at the time the Conference adopted the amendment. Any amendments thus accepted shall bind all the States which are Members of the Organization at the time the amendment enters into force or which become Members at a subsequent date, provided that any amendment increasing the financial obligations of Member States shall bind only those States which have notified their acceptance of such amendment.
