States cannot deem convicts mentally fit for execution based on an IQ test score alone, the Supreme Court ruled Tuesday, making it less likely the mentally disabled will face the death penalty.
At issue was a Florida law that prevented death row inmates from introducing additional evidence of intellectual disability if they scored above 70 on an IQ test, a rule the high court said violated the Eighth Amendment’s prohibition on cruel and unusual punishment. Eight other states have similar laws, including Arizona, Alabama, Utah, Idaho, Kansas, Oklahoma, South Carolina and Arkansas.
The decision deals another blow to the death penalty, following weeks of controversy owing to the botched execution of Clayton Lockett in Oklahoma.
Justice Anthony Kennedy, joining the four Democratic-appointed Justices, wrote that Florida’s rule “creates an unacceptable risk that persons with intellectual disability will be executed, and thus is unconstitutional.” The other four conservative Justices joined a dissent authored by Justice Samuel Alito.
“An IQ score is an approximation, not a final and infallible assessment of intellectual functioning,” wrote Kennedy. “Intellectual disability is a condition, not a number.”
The death row inmate challenging Florida’s law is Freddie Lee Hall, who was convicted of kidnapping, raping and murdering a pregnant newlywed and then killing a sheriff’s deputy while robbing a convenience store in 1978. Kennedy writes in his opinion that family and teachers “identified [Hall] on numerous occasions as ‘mentally retarded.’” Nevertheless, Hall scored slightly above 70 on a number of IQ tests, rendering him fit for execution under Florida law. A 2002 Supreme Court opinion, Atkins v. Virginia, held that execution of the mentally disabled violates the Eighth Amendment’s prohibition on cruel and unusual punishment.
Alito’s dissent accuses Kennedy of holding the Constitution hostage to the decisions of medical professionals he cites in his opinion. “Under our modern Eighth Amendment cases, what counts are our society’s standards—which is to say, the standards of the American people—not the standards of professional associations, which at best represent the views of a small professional elite,” Alito wrote.
