Article 15

1. Any country may, at the time of signing this Convention or of depositing its instruments of ratification or accession, or at any subsequent time, declare that it accepts Protocol No. 1 concerning rights in rem in inland navigation vessels, annexed hereto; at the time of such declaration, or at any subsequent time, it may declare that it also accepts Protocol No. 2 on attachment and forced sale of inland navigation vessels, annexed hereto.

2. Protocol No. 1 shall be deemed to be an integral part of the Convention as between the Contracting Parties which have made declarations concerning that Protocol under paragraph 1 of this article; similarly, Protocol No. 2 shall be deemed to be an integral part of the Convention as between the Contracting Parties which have made declarations concerning that Protocol also. Nevertheless, if the declaration of a country is made after that country has become a Contracting Party to the Convention, the Protocol to which the declaration relates shall not be deemed to be an integral part of the Convention as between that Contracting Party and the other Contracting Parties which have made a like declaration until the expiry of the ninetieth day after notice of the declaration has been given to the Secretary-General of the United Nations.

3. Any Contracting Party which has made a declaration under paragraph 1 of this article may withdraw the same at any time by notice addressed to the Secretary-General; the withdrawal of a declaration concerning Protocol No. 1 shall imply the withdrawal of any declaration which may have been made concerning Protocol No. 2. The Protocol or Protocols in respect of which a Contracting Party notifies the withdrawal of its declaration shall cease to have effect for that Contracting Party twelve months after the date of the notice.
