Sean D. Murphy's wide-ranging and in-depth 2002 survey of U.S. practice in international law in the period 1999–2001 draws upon the statements and actions of the executive, legislative and judicial branches of the U.S. government to examine its involvement across a range of areas. These areas include diplomatic and consular relations, jurisdiction and immunities, state responsibility and liability, international organizations, international economic law, human rights, and international criminal law. At the time of its first publication this summary of the most salient issues was a central resource on U.S. practice in international law. The volume contains extracts from hard-to-find documents, generous citations to relevant sources, tables of cases and treaties, and a detailed index. Revealing international law in the making, this essential tool for researchers and practitioners was the first in a series of books capturing the international law practice of a global player.
