McWilliams v. Dunn
The Court ruled that Alabama violated a death row inmate's right to mental-health expert assistance at his capital sentencing, because the neurologist appointed by the trial court never helped the defense evaluate his findings, build arguments, or prepare witnesses before the deadline.
The decision sends the case back to the lower federal appeals court to decide whether that failure actually changed the outcome, leaving open a broader question about whether states must give defendants their own dedicated expert rather than a neutral one shared with the prosecution.
How it got here: Alabama courts and a federal magistrate and district court denied relief on habeas review; the Eleventh Circuit affirmed, and the Supreme Court agreed to review the Ake question.
The Case in Depth
What happened
James McWilliams was convicted of a 1984 rape and murder in Alabama and sentenced to death. Before his judicial sentencing hearing, his lawyers got new medical records and a report from a court-appointed neuropsychologist just days beforehand, and asked for more time and expert help to understand and use the material. The trial judge refused and imposed the death sentence.
The question before the Court
Did a death row inmate get the psychiatric help he was constitutionally owed, when a court-ordered expert only tested him and filed a report two days before sentencing, without ever helping his lawyers understand it, argue from it, or use it in court?
The Court's answer
No — Alabama did not give McWilliams the psychiatric help the Constitution requires. The Court found that while a court-appointed expert examined him and filed a report, no one ever helped his lawyers understand that report, build arguments from it, or use it at the sentencing hearing, which is what the Court's 1985 Ake decision demands beyond a bare examination.
The Court didn't decide the bigger question of whether states must give defendants an expert who works only for them rather than a shared neutral one — it found Alabama fell short even under the more modest reading of Ake. The case goes back to the lower court to decide whether this failure actually changed McWilliams's sentence.

Why it matters
Indigent defendants facing the death penalty depend on mental-health experts to explain complex medical evidence to judges and juries. This ruling tells states that simply ordering an exam and handing over a report at the last minute is not enough — the expert or someone like them must actually help the defense use that information, or the sentence can be challenged in federal court.
What changes now
The case returns to the Eleventh Circuit, which must now decide whether Alabama's failure to provide meaningful expert assistance actually had a substantial and injurious effect on McWilliams's sentence — not just whether a few extra days to review the report would have mattered. This is a final merits ruling on the constitutional violation, but the ultimate outcome for McWilliams's sentence remains undecided pending that harmless-error analysis.
What this does not decide
The Court explicitly declined to decide whether Ake requires states to give defendants a psychiatric expert who works exclusively for the defense, rather than a neutral expert shared with the prosecution — the question the Court had originally agreed to review. It also left the harmless-error question for the lower court to resolve on remand.
Concurrences and dissents
Dissent — Justice Alito
Justice Alito argued the Court should have answered the actual question it agreed to review — whether Ake requires a defense-team expert — and that Ake's text is genuinely ambiguous on that point, as shown by decades of conflicting lower-court rulings. He accused the majority of instead deciding a fact-bound question the Court had refused to review, without fair briefing from Alabama, and argued that any error was harmless given the strength of the aggravating evidence and McWilliams's own consistent malingering.
How the Court got there
The legal reasoning, step by step
- The Court relied on Ake v. Oklahoma, a 1985 decision holding that when an indigent defendant's mental state is a significant issue at trial or sentencing, the State must give the defense access to a competent psychiatric expert to conduct an examination and to help evaluate, prepare, and present the defense.
- The Court first confirmed that Ake's basic trigger conditions were met here: McWilliams was indigent and his mental condition was both relevant to his punishment and seriously in question, so some form of expert assistance was constitutionally required.
- The Court rejected Alabama's argument that a volunteer psychologist's earlier, informal help satisfied the State's duty, because nothing in the record showed she was available to assist at the actual sentencing hearing where the assistance was needed.
- Rather than deciding the broader question of whether Ake requires a defense-team expert as opposed to a neutral one, the Court found it unnecessary to reach that issue because Alabama had failed to meet even Ake's minimum requirements under either reading.
- Applying Ake's four listed functions — examination, evaluation, preparation, and presentation — the Court found that while an examination occurred, no expert ever helped translate the findings into legal strategy, helped rebut the malingering theory, or helped prepare or present testimony at the hearing.
- Because the State's mental-health assistance fell so far short of what Ake requires, the Court concluded that the Alabama courts' decision upholding the sentence was contrary to, or an unreasonable application of, clearly established federal law under the deferential habeas standard.
