Editing Habeas corpus (section)

===Spain===
The present [[Constitution of Spain]] states that "A ''habeas corpus'' procedure shall be provided for by law to ensure the immediate handing over to the judicial authorities of any person illegally arrested". The statute which regulates the procedure is the ''Law of Habeas Corpus of 24 May 1984'', which provides that a person imprisoned may, on her or his own or through a third person, allege that she or he is imprisoned unlawfully and request to appear before a judge. The request must specify the grounds on which the detention is considered to be unlawful, which can be, for example, that the custodian holding the prisoner does not have the legal authority, that the prisoner's constitutional rights have been violated, or that he has been subjected to mistreatment. The judge may then request additional information if needed, and may issue a ''habeas corpus'' order, at which point the custodian has 24&nbsp;hours to bring the prisoner before the judge.

Historically, many of the territories of Spain had remedies equivalent to the ''habeas corpus'', such as the privilege of ''manifestación'' in the [[Crown of Aragon]] or the right of the Tree in [[Biscay]].
