Traditionally, the theory of human rights limited its application to the public domain, namely the relationships between individuals and public authorities. The great expansion of human rights legislation and concepts in modern national and international law has given rise to a major issue relating to their potential impact on private relationships. This work examines this important topic, which may revolutionize private law. It presents new approaches which strive to broaden the application of human rights to the private field on the ground that power can be abused and human rights can be infringed even when all parties are private. The subject is examined from theoretical and comparative perspectives by leading scholars representing a diversity of legal systems - the United States, Canada, England, South Africa, Germany and Israel.
