Habeas corpus, etc. is a legal term referring to the right of an individual to challenge their detention or imprisonment in court. It is derived from a Latin phrase meaning 'you may have the body, ' and is often used in conjunction with other legal terms such as habeas corpus ad subjiciendum and habeas corpus ad prosequendum. The term is most commonly used in the United States, where it is protected by the Constitution. The writs associated with habeas corpus are court orders that require a person to be brought before a judge or other official so that the legality of their detention can be determined.
