3) treaty applies in full b/w reserving State and other States, except for the provisions covered by the reservation, which have the scope suggested by the reservation

*must be invoked by the injured/victimized State

*can invalidate only the problem provisions, not entire treaty

Rebus sic stantibus—when there is a change in the basic conditions underlying the making of a treaty

A new jus cogens is in conflict with an existing treaty

9.7 Termination of Treaties

The possibility of withdrawal depends on the terms of the treaty

Cannot withdraw from Human Rights Treaties: the International Covenant on Civil and Political Rights

North Korea declared its intention to do this the Secretary-General of the United Nations, acting as registrar, said that that original signatories of the ICCPR had not overlooked the possibility of explicitly providing for withdrawal, but rather had deliberately intended not to provide for it. Consequently withdrawal was not possible.

Suspension of Treaty

In cases in which a treaty is breeched, depending on the treaty, States may temporarily suspend their obligations to that party under the treaty
