Help with trial lawyer claims

Luis Mariano Martinez v. Ryan

Updated Oct 18, 2026

In brief

The Supreme Court overturned the Ninth Circuit's ruling and sent Martinez's case back, without deciding whether his lawyers were ineffective or whether he was harmed.

Where it stands
Decided

Decided 7-2 · March 20, 2012 · Opinion by Justice Kennedy

What it’s about
The Supreme Court ruled that if state law requires a person to raise a claim that trial counsel was ineffective in the first post-conviction case (a court challenge after conviction), the person may sometimes overcome the state’s rule blocking review if there was no lawyer, or an ineffective lawyer, in that case and the trial-counsel claim has some merit.
Who it affects
Martinez's claim is not resolved; the Ninth Circuit must still assess his first post-conviction lawyer's work, the strength of his trial-lawyer claim, and whether he was harmed.

What it's about

The Court overturned the Ninth Circuit and sent Luis Martinez’s case back to the lower court (remanded); whether his post-conviction lawyer performed inadequately, his trial-counsel claim had merit, and he was harmed remained undecided.

The dispute concerns a state system where a defendant cannot raise a claim that trial counsel was ineffective on direct appeal but can raise it in the first court challenge after conviction.

Question presented

May a defendant in a state criminal case who is prohibited by state law from raising on direct appeal any claim of ineffective assistance of trial counsel, but who has a state-law right to raise such a claim in a first post-conviction proceeding, establish cause for a procedural default of a claim of ineffective assistance at trial by showing ineffective assistance at the initial-review collateral proceeding?

What the Court decided

Holding

Whether Martinez’s attorney in his first collateral proceeding was ineffective and whether his ineffective-assistance-at-trial claim is substantial, as well as the question of prejudice, are questions that remain open for a decision on remand. 623 F. 3d 731, reversed and remanded.

What's next

The case returns to the Ninth Circuit. It must decide whether Martinez's lawyer in his first court challenge after conviction was ineffective, whether his claim about his trial lawyer has enough merit, and whether any error harmed him.
