Shoop v. Twyford, 596 U.S. 811

Background

Raymond Twyford was convicted in Ohio of aggravated murder and sentenced to death; state courts rejected his ineffective-assistance and related claims (including a theory based on a teenage head injury).
Twyford filed a federal habeas petition under AEDPA; the District Court dismissed many claims as procedurally defaulted but allowed some to proceed.
Twyford sought a District Court order under the All Writs Act directing the State to transport him to a medical center for neurological testing to develop evidence supporting his habeas claims; he asked the court not to decide admissibility first.
The District Court granted the transport order; the Sixth Circuit affirmed without resolving whether any resulting evidence would be admissible in habeas proceedings.
The Supreme Court reversed, holding that a transportation order enabling a prisoner to search for new evidence is not "necessary or appropriate in aid of" a federal habeas court’s jurisdiction unless the prisoner shows the sought evidence would be admissible as to a particular claim, and explaining that All Writs relief cannot be used to evade AEDPA limits on new evidence.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
1. Whether the All Writs Act generally authorizes transportation for medical testing	Twyford: All Writs permits federal courts to issue orders needed to develop evidence for habeas claims	State: The Act does not authorize transportation orders for this purpose (or at least not here)	Not decided on the merits — Court resolved case on narrower grounds and declined to reach the general question
2. Whether a transport order is "necessary or appropriate in aid of" habeas jurisdiction when the prisoner hasn't shown resulting evidence would be admissible	Twyford: Testing could "plausibly" produce evidence relevant to his claims and to excuse procedural default	State: AEDPA restricts consideration of new evidence; petitioner failed to show admissibility or satisfy §2254(e)(2)	Held: Order was improper — court must require a showing that the evidence would be admissible as to a particular claim before issuing such a transport order
3. Whether a district court may use the All Writs Act to facilitate development of new evidence without first applying AEDPA's limits	Twyford: Asked the court to permit testing now and defer admissibility questions	State: All Writs cannot be used to circumvent AEDPA's restrictions on new evidence	Held: AEDPA governs; courts must consider AEDPA limits before using All Writs to develop evidence
4. Whether the Court of Appeals had jurisdiction to hear an interlocutory appeal of the transport order	State (and majority below): Transportation orders are immediately appealable under the collateral-order doctrine	Twyford (and dissent): Such orders are like discovery and not fit for immediate appeal; collateral-order doctrine should remain narrow	Held: Majority (superseding opinion) treated the order as immediately appealable; dissent disagreed and would have dismissed for lack of jurisdiction
