Quick answer

The writ of habeas corpus is a fundamental safeguard of personal liberty, often called the great writ. It is a remedy that directs the person detaining another to produce the body of the detained person before the court and to justify the legality of the detention; if the detention is found to be illegal, the court orders the person's release. The writ extends to all cases of illegal confinement or detention by which any person is deprived of their liberty, or by which the rightful custody of a person is withheld from the one entitled to it. In criminal matters, habeas corpus is commonly invoked to challenge a detention that has no legal basis, such as an arrest without a warrant that does not fall under the valid warrantless-arrest exceptions, a detention beyond the periods allowed before charges are filed, or continued detention despite the service of the full sentence or the grant of bail. However, the writ has important limits. The most significant is that habeas corpus generally will not lie, or the illegality of the detention is deemed cured, once the person is detained under a valid judicial process, such as a warrant of arrest or a commitment order issued by a court with jurisdiction, or after the filing of an information and arraignment; at that point, the remedy is within the criminal case itself (for example, by moving to quash or to be admitted to bail), not by habeas corpus. Habeas corpus is also used in non-criminal contexts, notably to determine the rightful custody of a minor. The writ may be filed with the Supreme Court, the Court of Appeals, or the Regional Trial Court. So habeas corpus is a swift remedy to test the legality of a detention and free a person illegally held, but it generally does not lie once the detention is under valid judicial process.

The Great Writ

Habeas corpus directs the detainer to produce the detained person and justify the detention. If the detention is illegal, the court orders release. It extends to all cases of illegal confinement or withheld rightful custody.

When It Lies in Criminal Matters

It challenges a detention with no legal basis — an invalid warrantless arrest, detention beyond the allowed periods before charging, or continued detention despite a served sentence or a grant of bail.

The Key Limit

Habeas corpus generally does NOT lie once the person is held under valid judicial process (a warrant, commitment order, or after an information and arraignment) — the remedy is then within the criminal case (motion to quash, bail). The writ is also used for child custody.
