Shoop v. Twyford

Decided June 21, 2022. John Glover Roberts Jr. delivered the opinion of the Court.

Docket 21-511 · 596 U.S. 811 · Cited 156 times

A transportation order that allows a prisoner to search for new evidence—in this case an order compelling the State to transport Mr. Twyford to a medical facility for neurological testing—is not “necessary or appropriate in aid of” a federal court’s adjudication of a habeas corpus action when the prisoner has not shown that the desired evidence would be admissible in connection with a particular claim for relief.
