Habeus Corpus, for one, is a Latin term meaning 'you have the body' and is a legal term used in the United States. It is a fundamental principle of American law that requires that a person be brought before a court to determine if they are being lawfully detained. This right is guaranteed by the U.S. Constitution and is often referred to as the 'Great WRIT'. The term is also used in other countries, such as the United Kingdom, where it is known as habeas corpus ad subjiciendum. The term is also used in international law, where it is known as the right to a fair trial.
