Hamm v. Smith
Death‑penalty case about how to weigh multiple IQ tests is dismissed; the Court refused to set a national rule, leaving people facing execution and state courts to rely on existing approaches.
Holding
The Court dismissed the writ of certiorari as improvidently granted, declining to decide how courts should consider multiple IQ scores in Atkins claims and leaving the lower‑court decision in place.
Real-world impact
- No new national rule on weighing multiple IQ tests in death‑penalty cases.
- Leaves state and federal courts free to use their own evaluation methods.
- People facing execution with multiple IQ scores may get different outcomes across courts.

Summary
Background
Joseph Smith, a man on Alabama’s death row, was convicted of a 1998 first‑degree murder and sentenced to death. After this Court’s decision in Atkins, Smith argued he is intellectually disabled and therefore cannot be executed. Over many years he took several IQ tests with scores ranging from 72 to 78. The parties presented experts and school records. A federal district court held an evidentiary hearing, found Smith intellectually disabled, and vacated his death sentence; the Eleventh Circuit later affirmed using a holistic approach.
Reasoning
The key question was how courts should weigh multiple IQ test results when deciding Atkins claims about intellectual disability and execution. The parties and experts agreed there is no single, universally accepted method. The Court explained that the record and the briefing in this specific case did not present the focused factual and legal development needed to adopt a national rule. Justice Sotomayor wrote that scientific disagreement, the way the case was litigated below, and the lack of developed lower‑court practice made it inappropriate for this Court to supply more detailed guidance now.
Real world impact
Because the Court dismissed the writ as improvidently granted, it did not issue a new national rule on how to combine or weigh multiple IQ scores. That leaves state and federal trial and appellate courts to continue using their own procedures and expert evidence. People facing execution who have multiple IQ tests may see different results in different courts. The dismissal is not a final merits decision and future cases could produce clearer national guidance.
Dissents or concurrances
Justice Sotomayor, joined by Justice Jackson, concurred in dismissing the case and explained why the district court’s holistic review fit existing precedent and medical guidance. Justices Thomas and Alito dissented; they argued the Court should have given clearer rules or even overturned Atkins, and they criticized the lower courts’ reliance on certain IQ evidence.
