Reservations to Treaties: the New ‘Guide to Practice’

15th November 2011

Reservations to treaties is one of the most difficult and controversial areas of treaty law. It has great practical consequences, including for international human rights law. In August 2011, the UN International Law Commission (ILC) adopted a 'Guide to Practice' on the subject. The Guide to Practice is the outcome of some 15 years of effort. Its impact will depend upon its reception by States and others, but is likely to be considerable. This event will be an early opportunity to discuss the law of reservations and Guide to Practice with Professor Alain Pellet, the ILC's Special Rapporteur for the topic.

The relevant documents can be found on the webpage of the Sixty-third Session of the ILC which is accessible here:

The documents in question are:

The Text and title of the draft guidelines [A/CN.4/L.779]
The Annex on reservations dialogue [L.793]
The Recommendation on mechanisms of assistance [L.795]
