Article 42. Validity and continuance in force of treaties
1. The validity of a treaty or of the consent of a State to be bound by a treaty may be impeached only through the application of the present Convention.

2. The termination of a treaty, its denunciation or the withdrawal of a party, may take place only as a result of the application of the provisions of the treaty or of the present Convention. The same rule applies to suspension of the operation of a treaty.

Article 43. Obligations imposed by international law independently of a treaty
The invalidity, termination or denunciation of a treaty, the withdrawal of a party from it, or the suspension of its operation, as a result of the application of the present Convention or of the provisions of the treaty, shall not in any way impair the duty of any State to fulfil any obligation embodied in the treaty to which it would be subject under international law independently of the treaty.

Article 44. Separability of treaty provisions
1. A right of a party, provided for in a treaty or arising under article 56, to denounce, withdraw from or suspend the operation of the treaty may be exercised only with respect to the whole treaty unless the treaty otherwise provides or the parties otherwise agree.

2. A ground for invalidating, terminating, withdrawing from or suspending the operation of a treaty recognized in the present Convention may be invoked only with respect to the whole treaty except as provided in the following paragraphs or in article 60.

3. If the ground relates solely to particular clauses, it may be invoked only with respect to those clauses where:
 * (a) the said clauses are separable from the remainder of the treaty with regard to their application;
 * (b) it appears from the treaty or is otherwise established that acceptance of those clauses was not an essential basis of the consent of the other party or parties to be bound by the treaty as a whole; and
 * (c) continued performance of the remainder of the treaty would not be unjust.

4. In cases falling under articles 49 and 50 the State entitled to invoke the fraud or corruption may do so with respect either to the whole treaty or, subject to paragraph 3, to the particular clauses alone.
