Obligation not to defeat the object and purpose of a treaty prior to its entry into force A State is obliged to refrain from acts which would defeat the object and purpose of a treaty when:
(a) it has signed the treaty or has exchanged instruments constituting the treaty subject to ratification, acceptance or approval, until it shall have made its intention clear not to become a party to the treaty; or (b) it has expressed its consent to be bound by the treaty, pending the entry into force of the treaty and provided that such entry into force is not unduly delayed.
