The ILC Guide to practice on reservations to treaties: A general presentation by the special rapporteur

Abstract

The purpose of this article is to revisit the long saga of the ILC Guide to Practice on Reservations to Treaties, as the Special Rapporteur has lived it for nearly 18 years and 16 reports. In its first part, the article recounts the elaboration procedure, pointing in particular to the elements of innovation and flexibility introduced in the process. The main one is the very type of instrument adopted, namely a Guide to Practice, and not a set of draft Articles that would eventually become a convention. In the second part, the main issues having retained the attention of the ILC, as well as of the other international bodies and of the academic community, are briefly recalled: the question of the unity or diversity of regimes, the permissibility of reservation and the status of the author of an impermissible reservation were among the most debated issues. Finally, the article explains the structure of the Guide to Practice. © The Author, 2013. Published by Oxford University Press on behalf of EJIL Ltd. All rights reserved.
