Artikel 16

The present Protocol shall be ratified and the instruments of ratification deposited with the Secretary-General of the Council of Europe. It shall enter into force as soon as three signatories representing at least one-third of the Fund's holdings have deposited their instruments of ratification. For the other Members of the Fund it shall enter into force on the date when their respective instruments of ratification are deposited.
Nevertheless, pending the entry into force of this Protocol in accordance with the foregoing paragraph, the signatories agree, in order not to delay the satisfactory operation of the Fund, to apply the Protocol provisionally from 1st September 1958, or, at latest, from the date of signature, to the extent compatible with their constitutional rules.
