Habeas corpus

Habeas corpus: Latin for "you have the body." A court order, or writ, requiring that a person held in custody be brought before the court so it can decide whether the detention is lawful. The U.S. Constitution provides that the privilege of the writ shall not be suspended unless, in cases of rebellion or invasion, the public safety may require it (art. I, § 9).

What habeas corpus means

In practice, you will see habeas corpus in pleadings, motions, orders and court rules. The definition above explains the general meaning. Even so, the meaning can shift with context. Therefore, always read it alongside the rule or document where it appears.

Where habeas corpus comes up

The term is used across many kinds of cases. For example, you may see it in pleadings, motions and court orders. To see it in context, browse the motions and procedures library or the Learn the Law topics.

How to research the term

Start with the primary source. For example, if habeas corpus appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read habeas corpus in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.
