Missed claims about trial lawyers
Trevino v. Thaler
In brief
The Court said the Martinez exception applies to Texas, wiped out the Fifth Circuit's ruling, and sent Trevino's case back without deciding his underlying claim.
- Where it stands
- Decided
Decided 5-4 · May 28, 2013 · Opinion by Justice Breyer
- What it’s about
- The Court ruled that Texas’s procedures trigger the Martinez exception: a federal court may hear a substantial claim that trial counsel was ineffective if the lawyer in the first state review was absent or ineffective, because such claims are highly unlikely to be meaningfully raised on direct appeal.
- Who it affects
- For Texas prisoners, the exception can let a federal court hear a substantial claim that trial counsel was ineffective if the lawyer in the first state review was absent or ineffective and Texas rules made a meaningful appeal unlikely.
Summary: written with AI from the case record.

What it's about
It wiped out the Fifth Circuit’s ruling (vacated it) and sent the case back (remanded), without deciding Trevino’s claim.
Texas law appeared to allow defendants to raise trial-lawyer claims on direct appeal, but the dispute was whether the Martinez exception still applied.
Question presented
Can the ineffective assistance of a criminal defendant's counsel during state habeas proceedings excuse his failure to properly claim ineffective assistance earlier in the proceedings?
What the Court decided
Holding
Where, as here, a State’s procedural framework, by reason of its design and operation, makes it highly unlikely in a typical case that a defendant will have a meaningful opportunity to raise an ineffective-assistance-of-trial-counsel claim on direct appeal, the exception recognized in Martinez applies. 415, vacated and remanded.
- Result
- Vacated
The Court's reasoning
The Court said Texas's rules make it highly unlikely that defendants can meaningfully raise a claim about trial counsel on an appeal directly after conviction. So the Martinez exception applies.
The vote
From the opinions
“That line lacks any principled basis, and will not last.”
What's next
The case returns to the Fifth Circuit for further proceedings under the Court's ruling; Trevino's underlying claim remains unresolved.
