- Abstract:
- This paper examines the legal validity of reservations, understandings, and declarations (RUDs) in both U.S. and international courts. The analysis is based on 46 U.S. cases discussing RUDs as a general category and 26 U.S. cases discussing interpretative understandings and declarations, out of approximately 650 reviewed cases. The analysis is also based on 13 cases from international courts out of approximately 300 reviewed cases, including cases from the International Court of Justice (ICJ), the United Nations Convention on the Law of the Sea (UNCLOS) tribunal and arbitral bodies, the European Court of Human Rights, and the Inter- American Court of Human Rights. In the U.S. cases, RUDs are nearly always recognized as valid. For example, non-self- execution reservations in the Convention Against Torture (CAT) and the International Covenant on Civil and Political Rights (ICCPR) are usually treated as legally controlling. The same is true for the reservation to the ICCPR that reserves the right to use capital punishment on juveniles despite treaty prohibitions, as well as interpretative understandings and declarations defining specific terms used in the CAT. U.S. courts have only questioned the validity of RUDs when they were not properly communicated to other state parties, did not support a contrary interpretation, or focused on issues of wholly domestic concern (although the only case on this point was vacated and is not precedential). In addition, individual circuit judges, writing in dissent, have examined whether RUDs violate the separation of powers principle or are inconsistent with the treaty language and international law. With few exceptions, international courts also usually defer to RUDs. The ICJ has indicated that it can invalidate a reservation as incompatible with the object and purpose of a treaty pursuant to Article 19 of the Vienna Convention on the Law of the Treaties. Yet the ICJ has only invalidated a RUD when it determined that a reservation was in fact an interpretative declaration (as opposed to a reservation modifying the state’s legal obligations under the treaty). This has been particularly important in cases where the treaty in question prohibits reservations, such as the UNCLOS. Rules stipulated by a treaty also shape how other courts review RUDs. The European Court of Human Rights, for instance, applies treaty rules to invalidate RUDs that are of a general character or fail to include a statement of the law concerned. Following a number of practices can reduce a RUD’s vulnerability to invalidation in U.S. and international courts. For U.S. courts, a RUD is extremely unlikely to be questioned if it is documented clearly at the time of ratification and communicated to all treaty parties at the time of ratification. For international courts, a RUD is unlikely to be questioned if, in addition to the above factors, it is not counter to the “object and purpose” of a treaty, it is not objected to by other parties, and it is not a reservation masquerading as an interpretive declaration in a situation where reservations are prohibited by the relevant treaty.
