Final provisions - Art. 70.
Art. 70. The Powers represented at the London Naval Conference attach particular importance to the general recognition of the rules which they have adopted, and therefore express the hope that the Powers which were not represented there will accede to the present Declaration. They request the British Government to invite them to do so.
A Power which desires to accede shall notify its intention in writing to the British Government, and transmit simultaneously the act of accession, which will be deposited in the archives of the said Government.
The said Government shall forthwith transmit to all the other Powers a duly certified copy of the notification, together with the act of accession, and communicate the date on which such notification was received. The accession takes effect sixty days after such date.
In respect of all matters concerning this Declaration, Acceding Powers shall be on the same footing as the Signatory Powers.
