Hundreds of American Indian tribes operate their own justice systems. Their courts decide thousands of cases a year. Many span the full panoply of law—from criminal, civil, and probate cases, to divorce and environmental disputes. Tribal Law is a survey of the laws that tribes enact to govern themselves. It considers issues ranging from governance (elections, justice systems, and tribal constitutions), to conflicts between individuals (contracts, property, domestic relations, torts), to regulation of a tribal community’s economy.
