Treaties, Human Rights, and Conditional Consent

The U.S. treaty-makers have consistently attached conditions to their consent to modern human rights treaties, in the form of reservations, understandings, and declarations ("RUDs"). Through these RUDs, the treatymakers have sought to limit their consent to international obligations that the United States is constitutionally and politically able to comply with, and to ensure that these obligations are implemented in a manner consistent with principles of separation of powers and federalism. The conventional wisdom among scholars is that the RUDs are invalid under international law and U.S. domestic law, and are harmful to the international human rights movement. This Article challenges the conventional wisdom about RUDs. It argues that the RUDs serve as a useful bridge between isolationists who want to preserve the United States' sovereign prerogatives, and internationalists who want the United States to increase its involvement in international institutions -- a political divide that has had a debilitating effect on U.S. participation in international human rights regimes since World War II. In addition, RUDs help reconcile fundamental changes in international law with the requirements of the U.S. constitutional system. The RUDs achieve these ends in ways that are valid under both international and domestic law.
