The possibility of withdrawal depends on the terms of the treaty and its preparations. For example, it was found that it was not possible to withdraw from the International Covenant on Civil and Political Rights.

A treaty is invalidated either because of the circumstances in which a State party has acceded to the treaty, or because of the very content of the treaty. Cancellation is separate from termination, suspension or termination (addressed above), all of which involve a change in the consent of the parties to a previously valid contract, not the nullity of that consent in the first place. Reserves are essentially reservations about the adoption of a treaty by a state.
