Hall v. Florida
Headline: Court strikes down Florida’s rigid IQ-70 cutoff in death cases, requiring states to allow people with borderline scores to show intellectual disability before execution proceeds.
Holding: The Court held Florida’s rigid IQ-70 cutoff unconstitutional and ruled that defendants whose scores fall within the test’s margin of error must be allowed to present additional evidence of intellectual disability before execution may proceed.
- Prevents states from using a rigid IQ-70 cutoff to block further disability evidence.
- Allows death-row prisoners with borderline IQs to present adaptive-functioning evidence.
- Requires courts to account for IQ tests' margin of error when assessing disability.
Summary
Background
Freddie Lee Hall is a man convicted of two murders in 1978 and sentenced to death. He, school records, family members, and medical experts presented evidence over decades that he had significant cognitive and adaptive limitations. Hall’s IQ tests across 40 years produced scores ranging from 60 to 80, and the most recent score admitted at the hearing was 71. Florida law and the Florida Supreme Court treated any IQ above 70 as a bar to further proof of intellectual disability, blocking additional evidence at sentencing.
Reasoning
The Court asked whether Florida’s fixed cutoff followed the Eighth Amendment rule that executing someone with intellectual disability is cruel and unusual. Relying on Atkins and medical definitions, the majority explained that IQ scores are imprecise and should be read as a range because tests have a standard error of measurement (SEM). By treating a single IQ number as conclusive and barring adaptive‑behavior evidence, Florida’s rule creates an unacceptable risk of executing people who are intellectually disabled. The Court concluded the rule is unconstitutional and reversed the Florida Supreme Court.
Real world impact
The ruling means people on death row with IQ scores near the 70 cutoff cannot be excluded from showing lifelong adaptive limitations. Courts must allow defendants to introduce non‑IQ evidence and consider measurement error in IQ testing. The decision requires states that used rigid cutoffs to change procedures and sends Hall’s case back to state court for reconsideration consistent with this opinion.
Dissents or concurrances
A dissent argued the Court oversteps by relying heavily on professional associations and by imposing a national rule, maintaining Florida’s approach was within state discretion and that the majority’s change will cause uncertainty.
