What Is Habeas Corpus?
A writ of habeas corpus (which literally means to "produce the body") is a Court Order demanding that a public official (such as a warden) deliver an imprisoned individual to the Court and show a valid reason for that person's detention.
In many countries, authorities may take citizens and incarcerate them for months or years without charging them. Those imprisoned have no legal means to protest or challenge the imprisonment.
The framers of the U.S. Constitution wanted to prohibit this kind of abuse of power in the new United States. Therefore, they included a specific clause in the Constitution to safeguard the right, known as habeas corpus.
Writ of Habeas Corpus: How it Works
The procedure provides a means for prison inmates, or others acting on their behalf, to dispute the legal basis for confinement.
Habeas corpus has deep roots in English common law. Often, the court holds a hearing on the matter, during which the inmate and the government can both present evidence about whether there is a lawful basis for jailing the person. The court may also issue and enforce subpoenas in order to obtain additional evidence.
Depending on what the evidence reveals, the Judge may grant the inmate relief such as:
*Release from prison,
*Reduction in the sentence,
*An order halting illegal conditions of confinement, or
*A declaration of rights.
