John Q. Hamm, Commissioner, Alabama Department of Corrections, Petitioner v. Joseph Clifton Smith

Joseph Clifton Smith was sentenced to death in Alabama, but he argues that his intellectual disability makes his execution unconstitutional. The Supreme Court is reviewing whether courts must consider the cumulative effect of multiple IQ scores, especially when some results are above 70, to determine if a person has significantly subaverage intellectual functioning.

This case will determine how states must evaluate a defendant's mental capacity before carrying out a death sentence. If the Court sets a strict rule for IQ scores, it could change who is eligible for the death penalty in states like Alabama and impact many pending capital punishment cases.

Under the Eighth Amendment, the government is prohibited from executing people with intellectual disabilities. This case follows a long line of legal battles over how to measure a person's intelligence fairly and accurately when their life is on the line.

During oral arguments, the discussion focused on how to handle varying IQ test results and whether a single score above 70 should automatically disqualify a defendant from claiming an intellectual disability.

The Court must decide if a defendant's multiple IQ scores should be looked at together or if high scores can be used to dismiss disability claims.

The Supreme Court has finished hearing oral arguments and will now deliberate in private. A written decision is expected by the end of the Court's term in June 2026.

The core dispute is whether the Eighth Amendment requires courts to look at all IQ scores together. Alabama argues that scores above 70 should be treated differently than lower scores.

A ruling for Smith could allow other inmates with borderline IQ scores to challenge their sentences. It ensures that states use a more complete picture of a person's mental abilities.

The Court is clarifying the Atkins v. Virginia rule, which bans executing the intellectually disabled. They are defining exactly how 'subaverage intellectual functioning' must be proven in court.

The justices will vote on the case and assign a member to write the official opinion. Smith's execution remains stayed (paused) until the Court issues its final ruling.

This case shows the Court's ongoing effort to refine the specific protections of the Eighth Amendment. It highlights the tension between state power and federal constitutional limits on punishment.
