A writ (court order) that commands an individual or a government official who has restrained another to produce the prisoner at a designated time and place so that the court can determine the legality of custody and decide whether to order the prisoner's release.
A writ of habeas corpus directs a person, usually a prison warden, to produce the prisoner and justify the prisoner's detention. If the prisoner argues successfully that the incarceration is in violation of a constitutional right, the court may order the inmate's release. Habeas corpus relief may also be used to obtain custody of a child or to gain the release of a detained person who is insane, is a drug addict, or has an infectious disease. Usually, though, it is a response to imprisonment by the criminal justice system.
A writ of habeas corpus is authorized by statute in federal courts and in all state courts. An inmate in state or federal prison asks for the writ by filing a petition with the court that sentenced him or her. In most states, and in federal courts, the inmate is given the opportunity to present a short oral argument in a hearing before the court. The petitioner may also receive an evidentiary hearing to establish evidence for the petition.

Latin: a court order that a specific person being detained be promptly produced, by the detaining authority, before a judge for a hearing to decide whether the detention is lawful.
A challenge made by a prisoner in regards to the legality of his or her detention.
While traditionally a criminal law remedy, it has been used in immigration, child custody, mental health and, more recently, in national or homeland security.
The predominant feature of martial law is the suspension of habeas corpus, effectively denying persons detained from having their detention challenged quickly and by an independent court or judge.
Encyclopedia Britannica
An ancient common-law writ, issued by a court or judge directing one who holds another in his custody to produce the body of the person before the court for some specified purpose. Although there have been and are many varieties of the writ, the most important is that used to correct violations of personal liberty by directing judicial inquiry into the legality of a detention. The habeas corpus remedy is recognized in the countries of the Anglo-American legal system but is generally not found in civil-law countries, although some of the latter have adopted comparable procedures.

Latin for "you have the body," it is a writ (court order) which directs the law enforcement officials (prison administrators, police or sheriff) who have custody of a prisoner to appear in court with the prisoner to help the judge determine whether the prisoner is lawfully in prison or jail. The writ is obtained by petition to a judge in the county or district where the prisoner is incarcerated, and the judge sets a hearing on whether there is a legal basis for holding the prisoner. Habeas corpus is a protection against illegal confinement, such as holding a person without charges, when due process obviously has been denied, bail is excessive, parole has been granted, an accused has been improperly surrendered by the bail bondsman or probation has been summarily terminated without cause. Historically called "the great writ," the renowned scholar of the Common Law, William Blackstone, called it the "most celebrated writ in English law." It may also be used as a means to contest child custody and deportation proceedings in court. The writ of habeas corpus can be employed procedurally in federal district courts to challenge the constitutionality of a state court conviction.

Lat. "you have the body" Prisoners often seek release by filing a petition for a writ of habeas corpus. A writ of habeas corpus is a judicial mandate to a prison official ordering that an inmate be brought to the court so it can be determined whether or not that person is imprisoned lawfully and whether or not he should be released from custody. A habeas corpus petition is a petition filed with a court by a person who objects to his own or another's detention or imprisonment. The petition must show that the court ordering the detention or imprisonment made a legal or factual error. Habeas corpus petitions are usually filed by persons serving prison sentences. In family law, a parent who has been denied custody of his child by a trial court may file a habeas corpus petition. Also, a party may file a habeas corpus petition if a judge declares her in contempt of court and jails or threatens to jail her.

The Constitution of the United States states that the privilege of habeas corpus cannot be suspended. In this context, habeas corpus means that a person held in jail or prison has the right to make the authority holding the person justify the imprisonment. The prisoner may ask for a hearing in which a court determines that the proceeding, which resulted in the person being restrained, was fair and lawful.

Habeas corpus(Latin: You (shall) have the body) is a legal action, or writ, through which a person can seek relief from the unlawful detention of him or herself, or of another person. It protects the individual from harming him or herself, or from being harmed by the judicial system. Of English origin, the writ of habeas corpus has historically been an important instrument for the safeguarding of individual freedom against arbitrary state action. A writ of habeas corpus ad subjiciendum, also known as "The Great Writ", is a summons with the force of a court order addressed to the custodian (such as a prison official) demanding that a prisoner be brought before the court, together with proof of authority, allowing the court to determine whether that custodian has lawful authority to hold that person; if not, the person shall be released from custody. The prisoner, or another person on his behalf (for example, where the prisoner is being held incommunicado), may petition the court or an individual judge for a writ of habeas corpus.
