Treaty Bodies

Abstract

Abstract This article contributes to existing understandings about the influence of human rights treaty bodies on the development of customary international law. It offers a method of assessing State responses to treaty body jurisprudence for the purposes of determining to what extent the responses push toward the reaffirmation or crystallisation of a customary rule of international law, namely the prohibition against torture. It speaks to the way in which, despite its status as a peremptory norm, the content of the norm is often challenged, but also incrementally expanding due in large part to the way in which treaty bodies engage and guide States both inside and outside of the primary reporting procedures. Ultimately, this article demonstrates that State practice and opinio juris are increasingly influenced by treaty bodies.
