The Oxford Guide to Treaties is the authoritative reference point for anyone studying or involved in the creation or interpretation of treaties and other forms of international agreement. For centuries, treaties have regulated relations among nation states. Today, they are the dominant source of international law. From trade relations to greenhouse gases, from shipwrecks to cybercrime, treaties structure the rights and obligations of states, internationalorganizations, and individuals. Being adept with treaties and international agreements is thus an indispensable skill for anyone engaged in international relations, including international lawyers, diplomats, international organization officials, and representatives of non-governmental organizations.This second edition of the award-winning volume from Professor Duncan B. Hollis provides a comprehensive guide to treaties, shedding light on the rules and practices surrounding the making, interpretation, and operation of these instruments. Foundational issues are covered, from defining treaties and their alternatives, to examining current theorizations about the treaty in international law. Chapters review specific stages in the treaty's life-cycle, including formation, application,interpretation, and exit. Special issues associated with treaties involving the European Union and other international organizations are also included. A section sampling over four hundred actual treaty clauses complements these scholarly treatments. These real examples help illustrate different approachestreaty-makers can take on topics such as entry into force, languages, reservations, and amendments.
