Opting out of Customary International Law

Opting out of Customary International Law

One of the most fascinating topics (for positivists like myself anyway) is how customary international law incorporates a consensual element via the idea of persistent objectors.  Questions, of course, abound over why persistent objectors get an exemption from a customary rule, when subsequent objectors do not (unless other states acquiesce in the subsequent objector’s departure from the rule, or take it as the beginning of a movement towards a new customary rule, etc.)  In recent years, the implications of state decisions to opt-out of or simply not comply with customary rules have garnered increasing scholarly attention.  Most recently, Curt Bradley and Mitu Gulati have joined the conversation with their article, Withdrawing from International Custom.  That paper will be the basis of a scholarly roundtable this Saturday at Duke Law School, appropriately titled, Opting out of Customary International Law.  Although the papers for the roundtable aren’t publicly available yet, here’s the agenda.
