This book is the first to examine sexual orientation from the viewpoint of international human rights law. It does not simply 'create' a platform of rights and argue for their 'introduction' in human rights law. Rather, it examines how extant international norms should be construed to include rights against discrimination on the basis of sexual orientation, including rights of privacy, equality, speech, expression, and association. It raises questions of cultural relativism, religious faith, social science, and legal theory. It will be of interest to international jurists, human rights organizations, gay rights organizations, constitutional scholars, and anyone interested in expanding the role of international human rights law as a formidable adversary of persecution and discrimination throughout the world.
