Compulsory Process Law and Legal Definition

Compulsory Process is a process with a warrant to arrest or attach, and which compels a person to appear in court as a witness. It also refers to the right of a defendant to have a court use its subpoena power to compel the appearance of material witnesses before the court. In Civil actions, the right is established by a Statute and in some states by the State Constitution. In Criminal cases, it is established by the due process clause of the Sixth Amendment of the United States Constitution.
