2. Subsequently, this Convention shall come into force in respect
of each State three months after that State has deposited its
instrument of ratification, acceptance or accession.

3. Accession to this Convention by a State not party to the 1952
Convention shall also constitute accession to that Convention; however,
if its instrument of accession is deposited before this Convention comes
into force, such State may make its accession to the 1952 Convention
conditional upon the coming into force of this Convention. After the
coming into force of this Convention, no State may accede solely to the
1952 Convention.

4. Relations between States party to this Convention and States
that are party only to the 1952 Convention, shall be governed by the
1952 Convention. However, any State party only to the 1952 Convention
may, by a notification deposited with the Director-General, declare
that it will admit the application of the 1971 Convention to works of
its nationals or works first published in its territory by all States party
to this Convention.
