In this Article, I examine the Visiting Mechanisms under the Convention against Torture (CAT) and the Optional Protocol thereto (OPCAT), applying an analytic approach resting on Foucault’s Discipline and Punish. I argue that international Visiting Mechanisms essentially constitute disciplinary apparatuses as depicted by Foucault. However, because they fail to recognise this functional similarity, they do not effectively apply the methods of inducing panoptic power. Most notably the concept of ‘hierarchical observation’ is hardly utilised at all. The two introduced legal (...) entities, the Committee against Torture under CAT, and the Subcommittee for the Prevention of Torture under OPCAT, both engage in visits to states with a view to eradicate torture and ill-treatment throughout the world. Critically examining their systemic design and practises reveals that the preventative ante hoc mandate of the Subcommittee is more effective than the post hoc inquiries of the Committee. Nevertheless, because both entities unfortunately fail to fully utilise panoptic power, the article concludes by offering a set of recommendations for both bodies that could arguably enhance their overall effectiveness.
