The essays selected for this volume, written by some of the world's most respected experts on human rights, encompass the development of human rights law from its philosophical underpinnings and address many of its current controversies. The collected essays explore the drafting of major human rights instruments, including the political challenges that shaped those instruments; examine the interrelationship of various claimed rights; and identify factors producing compliance with - and violation of - human rights law. Other contributions analyze the role of non-governmental organizations in achieving better human rights protections as well as the danger of claiming too many rights, and the tension between rights and security. Contrasting viewpoints in several essays highlight some of the key conflicts in the field. An introductory essay provides a roadmap marking the collection's major themes, and tracing the relationship between those themes. Taken together, the essays emphasize the legal underpinnings of the human rights regime and as such, the collection provides an essential, wide-ranging account of this important part of international law, procedure and practice.
