Hall v. Florida

Background

Freddie Lee Hall, a death-row prisoner, was convicted for two 1978 murders and sentenced to death. He presented decades of evidence showing low intellectual and adaptive functioning, including school records, family testimony, clinicians’ opinions, and multiple IQ tests that ranged from 60 to 80. At a postconviction hearing he had an IQ score of 71. Florida law defines intellectual disability by about two standard deviations below the mean (roughly IQ 70), but the Florida Supreme Court treated any score above 70 as a fixed cutoff barring further evidence.

Reasoning

The Court asked whether Florida’s rigid rule implements Atkins, which bars executing people with intellectual disability. The majority relied on the Eighth Amendment’s protection of human dignity, the medical understanding that IQ scores have a standard error of measurement (SEM) and should be read as a range, and evidence about how other States and professional groups assess disability. It concluded Florida’s interpretation treated a single score as conclusive, ignored SEM, and improperly blocked adaptive-functioning evidence, making the rule unconstitutional.

Real world impact

The ruling requires Florida courts to let defendants with IQ scores within a test’s error range present additional evidence about everyday functioning. It affects other death-row cases in States using strict cutoffs and sends such claims back to lower courts for further proceedings; the case was reversed and remanded.

Dissents or concurrances

Justice Alito’s dissent argued the Court overruled state discretion, relied too heavily on professional associations, and found no clear national consensus against Florida’s rule.
