- Where it stands
- Decided
Decided · May 18, 2020
- What it’s about

- Who it affects
- Martinez did not receive a new Supreme Court review of his claims. For people seeking federal habeas review (a challenge to detention after conviction), the Ninth Circuit's result remains in place in this case.
Summary: written with AI from the case record.
What it's about
The petition raised questions about judicial bias and whether mistakes by lawyers in post-conviction and federal habeas proceedings could excuse missed claims.
Question presented
Whether the rule this Court established in Martinez v. Ryan, 566 U.S. 1 (2012), and Trevino v. Thaler, 569 U.S. 413 (2013), that the ineffective assistance of post-conviction counsel can provide cause to excuse the procedural default of a claim of ineffective assistance of trial counsel, applies to a claim of ineffective assistance of trial counsel that is not raised in a defendant’s first federal habeas petition because his first federal habeas counsel was also ineffective.
What the Court decided
What's next
The Supreme Court has finished its docket action. Martinez's case remains governed by the Ninth Circuit's decision.
