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.

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.

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.
