This Liber Amicorum was written by prominent colleagues and friends of Professor Hanspeter Neuhold in honor of his 65th birthday. The collection celebrates his lifelong career devoted to bridging the gap between international relations and public international law. Contributions cover the fields of international relations, international law, human rights, international organizations, and the law of economic integration. Without a doubt, this is not only a fine tribute to Hanspeter Neuhold, but is also a welcome addition to every international law and international relations library.
