Rule of Law:
An attorney's recommendation to withdraw a weak or non-viable defense does not constitute deficient performance under the Sixth Amendment, even if there is 'nothing to lose' by pursuing it. Counsel is not required to present every available non-frivolous defense, and a reasonable strategic decision to abandon a claim with a dismal prospect of success is not ineffective assistance.
Facts:
- Alexandre Mirzayance stabbed his 19-year-old cousin nine times and shot her four times, after which he confessed.
- At trial, Mirzayance entered pleas of not guilty and not guilty by reason of insanity (NGI), leading to a bifurcated trial.
- During the guilt phase, the defense presented medical testimony that Mirzayance was insane and lacked the capacity for premeditation, seeking a conviction for a lesser offense than first-degree murder.
- The jury convicted Mirzayance of first-degree murder, thereby rejecting the defense's evidence regarding his mental state.
- Counsel's strategy for the subsequent NGI phase relied on presenting similar medical testimony supplemented by emotional testimony from Mirzayance's parents.
- On the morning the NGI phase was scheduled to begin, Mirzayance's parents refused to testify.
- After consulting with co-counsel, the lead attorney concluded the NGI defense was doomed to fail and advised Mirzayance to withdraw the plea.
- Mirzayance accepted his counsel's advice and withdrew his NGI plea.
Procedural Posture:
- Alexandre Mirzayance was convicted of first-degree murder in a California state trial court.
- Mirzayance filed a state postconviction petition alleging ineffective assistance of counsel, which was denied by the state trial court.
- The California Court of Appeal (an intermediate appellate court) affirmed the denial of his petition.
- Mirzayance filed a petition for a writ of habeas corpus in the U.S. District Court for the Central District of California, which was denied.
- The U.S. Court of Appeals for the Ninth Circuit reversed the District Court's denial and remanded for an evidentiary hearing.
- Following the hearing, the Magistrate Judge recommended granting the writ; the District Court adopted the recommendation and granted habeas relief.
- The Ninth Circuit affirmed the District Court's grant of the writ.
- The U.S. Supreme Court granted certiorari, vacated the Ninth Circuit's judgment, and remanded for reconsideration in light of another case.
- On remand, the Ninth Circuit again affirmed the grant of habeas corpus, prompting the current appeal to the U.S. Supreme Court.

Issue:
Does defense counsel provide ineffective assistance in violation of the Sixth Amendment by advising a client to withdraw a 'not guilty by reason of insanity' (NGI) plea when the jury has already rejected the factual basis for the NGI claim in the guilt phase and key emotional witnesses refuse to testify?
Opinions:
Majority - Justice Thomas
No. Defense counsel does not provide ineffective assistance by advising a client to withdraw an NGI plea under these circumstances. To establish an ineffective assistance of counsel claim under Strickland v. Washington, a defendant must prove both that counsel's performance was deficient and that the deficiency resulted in prejudice. Here, counsel's performance was not deficient. The court explicitly rejected the Ninth Circuit's 'nothing to lose' standard, stating the Supreme Court has never established such a rule for evaluating Strickland claims. Counsel's decision was a reasonable strategic choice made after the jury had already rejected the core of the mental state defense in the guilt phase, where the state had a higher burden of proof. With the parents' refusal to provide crucial emotional testimony, the NGI claim was left with duplicative, weak evidence that was almost certain to fail. Furthermore, Mirzayance failed to show prejudice, as there is no reasonable probability that a jury which had just found premeditation beyond a reasonable doubt would have then found him insane based on similar evidence where he bore the burden of proof.
Analysis:
This decision reinforces the high deference afforded to defense counsel's strategic decisions under the Strickland standard, particularly within the restrictive framework of AEDPA habeas review. By explicitly rejecting a 'nothing to lose' or 'only defense available' test, the Court clarifies that the Sixth Amendment does not compel counsel to pursue every non-frivolous defense, regardless of its viability. The ruling solidifies the principle that an attorney's reasonable appraisal of a claim's poor chances of success is a legitimate basis for recommending its abandonment. This makes it more difficult for defendants to succeed on ineffective assistance claims based on a lawyer's choice not to pursue a weak defense, emphasizing that the measure is objective reasonableness, not a post-hoc evaluation of what could have been tried.
