International courts are increasingly called upon to adjudicate socially divisive disputes. They are therefore exposed to a heightened risk of backlash that questions their authority and impedes the implementation of their judgments. This article puts forward an analytical framework for mapping the resilience techniques used by international courts to counter this growing resistance. Case studies involve the Court of Justice of the European Union, which has been cautious in its stance regarding democratic backsliding in Hungary and Poland, and the Caribbean Court of Justice, which has engaged in legal diplomacy while adjudicating both on the land rights of indigenous groups and on Lesbian Gay Bisexual Transgender Queer and Intersex (LGBTQI) rights. It is argued that, in order to effectively avoid and mitigate backlash, international courts should deploy resilience techniques that go beyond merely exercising their judicial function. The successful deployment of resilience techniques can allow international courts to become significant actors in global governance during a time of crisis for the international liberal order.
