Understanding the Persistent Objector Rule
23 Jan 2019, 18:00 – 19:00
UCL Laws / International Law Association (British Branch) Lecture
Speaker:
Professor James A Green (University of Reading)
Chair:
Dr Dane Azaria (UCL Laws)
About the lecture:
The persistent objector rule is a ubiquitous feature of modern international law literature, and all international lawyers are likely to be very familiar with the basic idea at the heart of it. The rule is said to offer states an ‘escape hatch’ from the otherwise universal binding force of customary international law, in that it provides that if a state persistently objects to a newly emerging norm of customary international law during the formation of that norm, then the objecting state is exempt from the norm once it crystallises. The rule is often seen as playing an important conceptual role in preserving the voluntarist claim that any norm of international law can only bind a state that has consented to be bound by it. At the same time, for all its ubiquity in scholarship, there remains relatively little understanding of exactly how the persistent objector rule works, and questions exist about the extent to which it is used. There is, indeed, a significant minority critique of the rule that disputes whether it exists in law at all, and, if it does, whether it has any meaningful value.
This presentation will argue that the persistent objector rule is used and, thus, exists. It will then give an overview of how the rule works, exploring the criteria for its operation. Finally, the value or desirability of the rule will be considered.
