'This Handbook is a collaborative effort by the authors to identify, through engagement with various stakeholders, the best practices in treaty-making. It is a comprehensive guide providing expertise on each stage of a treaty's lifespan including, reservation, ratification, amendments, etc. It condenses highly technical information into an accessible framework, making it an indispensable resource, not only for treaty experts, diplomats and administrators, but also lawyers, academics and students delving into the intricacies of treaty practice.' Gabrielle Marceau, Université de Genève and the World Trade Organization Senior Counsellor
