FYI...from Wikipedia
In common law countries, habeas corpus (/'heɪbiəs 'kɔɹpəs/), Latin for "you [should] have the body", is the name of a legal action or writ by means of which detainees can seek relief from unlawful imprisonment. But habeas corpus has a much broader meaning in common law today. A writ of habeas corpus is a court order addressed to a prison official (or other custodian) ordering that a prisoner be brought before the court for determination of whether that person is serving a lawful sentence and/or whether he or she should be released from custody. The writ of habeas corpus in common law countries is an important instrument for the safeguarding of individual freedom against arbitrary state action.
Habeas corpus can also mean that the imprisoning authority of an alleged murderer 'should have the body' to prove that there has indeed been a murder at all, but this usage is rare.
If I never post again after this, you'll know why.
