SECTION 3. ENTRY INTO FORCE AND PROVISIONAL
APPLICATION OF TREATIES
Article 24
Entry into force
1.A treaty enters into force in such manner and upon such date as it may provide or as the
negotiating States and negotiating organizations or, as the case may be, the negotiating organizations
may agree.
2.Failing any such provision or agreement, a treaty enters into force as soon as consent to be bound by the treaty has been established for all the negotiating States and negotiating organizations or, as the case may be, all the negotiating organizations.
3.When the consent of a State or of an international organization to be bound by a treaty is established on a date after the treaty has come into force, the treaty enters into force for that State or that organization on that date, unless the treaty otherwise provides.
4. The provisions of a treaty regulating the authentication of its text, the establishment of consent to be bound by the treaty, the manner or date of its entry into force, reservations, the functions of the depositary and other matters arising necessarily before the entry into force of the treaty apply from the time of the adoption of its text.
Article 25
Provisional application
1. A treaty or a part of a treaty is applied provisionally pending its entry into force if:
(a) the treaty itself so provides; or
(b) the negotiating States and negotiating organizations or, as the case may be, the negotiating organizations have in some other manner so agreed.
2. Unless the treaty otherwise provides or the negotiating States and negotiating organizations or, as the case may be, the negotiating organizations have otherwise agreed, the provisional application of a treaty or a part of a treaty with respect to a State or an international organization shall be terminated if that State or that organization notifies the States and organizations with regard to which the treaty is being applied provisionally of its intention not to become a party to the treaty.
