Social Pressure in the International Human Rights Regime: Why States Withdraw Treaty Reservations

Abstract

Abstract States often use reservations to modify their treaty obligations. Prior research demonstrates why states enter reservations and why states object to reservations, but little work explains why states withdraw them. We argue that states withdraw reservations in response to international social pressure. Using novel data on reservations and reservation withdrawals for the nine core international human rights treaties, our analyses reveal two factors that compel states to withdraw reservations: (1) pressure from peer states and (2) pressure from human rights treaty bodies conducting periodic reviews. While previous work emphasizes domestic factors, our research shows that the international community encourages states to withdraw reservations and strengthen their commitments to human rights and international law.
