Shinn v. Martinez Ramirez
The Supreme Court ruled that federal courts cannot hold evidentiary hearings or consider new evidence in habeas cases when a state prisoner's failure to build a record in state court was caused by an ineffective postconviction lawyer — even when the Court's own 2012 precedent allowed that same ineffectiveness to excuse the underlying procedural default.
The 6-3 decision significantly narrows the path to federal review for death row inmates and other prisoners who received inadequate legal help at both trial and in state postconviction proceedings, leaving many without a meaningful opportunity to prove constitutional violations in federal court.
How it got here: Federal district courts in Arizona held evidentiary hearings and forgave both prisoners' procedural defaults; the Ninth Circuit affirmed; Arizona petitioned the Supreme Court, which agreed to hear both cases together.
The Case in Depth
What happened
Two Arizona men sentenced to death — David Ramirez (convicted of two stabbing murders) and Barry Jones (convicted of murdering his girlfriend's 4-year-old daughter) — each argued that their trial lawyers had been constitutionally ineffective. But their state postconviction lawyers also failed to properly investigate and raise those claims in state court, leaving the factual record entirely undeveloped. When they reached federal court with competent counsel, both sought to introduce new evidence — including medical experts, family members, and forensic specialists — to support their claims.
The question before the Court
Can federal courts hold hearings and consider new evidence for death row inmates who say their trial lawyers were constitutionally inadequate, when the lawyers who handled their state postconviction appeals also failed to develop that evidence?
The Court's answer
No. A federal habeas court cannot hold an evidentiary hearing or consider evidence outside the state-court record simply because a prisoner's state postconviction lawyer negligently failed to develop that record — even when, under the Court's 2012 Martinez ruling, that same postconviction lawyer's ineffectiveness excuses the prisoner's failure to raise the claim in state court at all.
The key reason is that the relevant restriction comes from a federal statute — AEDPA's §2254(e)(2) — not a judge-made rule. Courts have equitable power to adjust judge-made doctrines like the procedural-default exception recognized in Martinez, but they have no authority to rewrite or add exceptions to statutory text. Under §2254(e)(2) and consistent prior decisions, a prisoner bears responsibility for their postconviction attorney's failures because there is no constitutional right to postconviction counsel, and Congress raised — not lowered — the standard for federal evidentiary hearings when it enacted AEDPA.

Why it matters
Death row inmates and state prisoners who believe their trial lawyers were constitutionally inadequate — but whose postconviction lawyers also failed to investigate and preserve those claims — will generally be barred from introducing new evidence in federal court. For prisoners in states like Arizona that channel ineffective-assistance claims into postconviction review, this ruling means some may face execution without ever having had competent counsel at any stage that actually developed their case.
What changes now
The cases are sent back to the lower courts, where the prisoners' habeas petitions will be assessed solely on the undeveloped state-court records that their postconviction lawyers failed to build. Without new evidence, their ineffective-assistance-of-trial-counsel claims are unlikely to succeed. The ruling immediately affects all state prisoners in federal habeas proceedings who sought to use the Ninth Circuit's approach, and it forecloses similar evidentiary development for prisoners in Arizona and the many other states whose systems channel trial-ineffective-assistance claims into postconviction review.
What this does not decide
The ruling does not decide whether Ramirez's or Jones' trial lawyers were actually constitutionally inadequate — their underlying claims may or may not have merit. The decision also does not overrule Martinez v. Ryan; the narrow equitable exception Martinez created for procedural default remains intact. It applies only to the separate question of new evidentiary development under §2254(e)(2).
Concurrences and dissents
Dissent — Justice Sotomayor
Justice Sotomayor argued that the majority's ruling is logically incoherent: it cannot make sense to excuse a prisoner's failure to raise a claim because of ineffective postconviction counsel (as Martinez requires) while simultaneously holding that same prisoner responsible for the same counsel's failure to develop evidence for that claim. She contended that Williams v. Taylor's fault-based reading of §2254(e)(2) should encompass the Martinez context, and that the majority guts both Martinez and Trevino v. Thaler as practical matters, leaving many death-row inmates with no meaningful opportunity to vindicate their Sixth Amendment right to effective trial counsel.
How the Court got there
The legal reasoning, step by step
- Federal habeas corpus is an 'extraordinary remedy' — not a substitute for ordinary appeals — available only to correct extreme malfunctions in state criminal justice. Because federal review overrides state sovereignty, AEDPA tightly restricts when it is available, including requiring prisoners to properly raise all claims in state court first (the 'exhaustion' rule) and generally prohibiting federal courts from considering claims a state court would have rejected on procedural grounds ('procedural default').
- When a prisoner's claim is procedurally defaulted, a federal court can still hear it if the prisoner shows 'cause' and 'actual prejudice.' The Court's 2012 Martinez decision carved out a narrow equitable exception to the usual rule that attorney error cannot be cause: if a state channels trial-ineffective-assistance claims into postconviction proceedings rather than direct appeal, an ineffective postconviction lawyer's failure to raise such a claim can count as 'cause' to excuse the procedural default.
- Separately, AEDPA's §2254(e)(2) governs whether a prisoner can introduce new evidence into federal habeas. If the prisoner 'failed to develop the factual basis of a claim' in state court, a federal evidentiary hearing is available only in two narrow scenarios — a newly recognized constitutional rule or a factual predicate that couldn't have been discovered with due diligence — and only if the prisoner can also prove actual innocence by clear and convincing evidence.
- Because there is no constitutional right to postconviction counsel, a prisoner bears responsibility for their postconviction lawyer's errors under well-established precedents, including Keeney v. Tamayo-Reyes, Williams v. Taylor, and Holland v. Jackson. Postconviction counsel's negligence is therefore attributed to the prisoner, who is 'at fault' for the undeveloped record under §2254(e)(2).
- The Court refused to extend Martinez's equitable exception to cover §2254(e)(2) factfinding because Martinez modified a judge-made procedural rule, while §2254(e)(2) is a statute that courts have no authority to rewrite. Congress enacted AEDPA to raise the bar on evidentiary hearings, not lower it, and Martinez itself explicitly foreclosed any extension of its 'narrow exception' beyond the procedural-default context.
- The Court also rejected a workaround under which prisoners would gather evidence at a 'cause-and-prejudice' hearing under Martinez, then use that same evidence to assess the merits of their underlying claim. Under Holland v. Jackson, §2254(e)(2)'s restrictions apply whenever a court considers new evidence for any purpose — so if the statute bars consideration of new evidence on the merits, a court may not hold any preliminary hearing designed to develop that same evidence.
Doctrinal impact
Cases affected by this decision
Limits Martinez v. Ryan (566 U.S. 1)
Martinez's equitable exception for procedural default is confined to that narrow context and cannot be extended to permit new evidentiary development under §2254(e)(2).
Reaffirms Holland v. Jackson (542 U.S. 649)
§2254(e)(2)'s restrictions apply any time a court considers new evidence, whether or not a formal hearing is labeled as such.
Reaffirms Williams v. Taylor (529 U.S. 420)
Postconviction counsel's failure to develop the state-court record is attributed to the prisoner, who is therefore 'at fault' under §2254(e)(2).
