WASHINGTON -- Florida officials say Freddie Lee Hall is smart enough to die for what he did.
On Monday, 36 years after the double murder that sent Hall to death row, the Supreme Court will consider whether Florida is right. The court's answer could mean life or death for Hall and other inmates whose below-average intelligence puts them on the borderline of eligibility for execution.
More prosaically, the eventual ruling will shape how well the death-penalty process works.
"This is a significant case because a decision the wrong way could lead to longer delays in carrying out sentences," Kent Scheidegger, of the Criminal Justice Legal Foundation in Sacramento, Calif., said in an interview Friday.
The American Bar Association shares the sense of significance, but for a different reason. The lawyers' organization warns that if Florida wins, "the execution of individuals with mental retardation" could be inevitable. With their competing legal briefs, Mr. Scheidegger and the bar association joined others in trying to sway the court in advance of Monday's hourlong oral argument.
The Supreme Court has already ruled out executing those variously called "mentally retarded" or "intellectually disabled," as a violation of the Eighth Amendment's prohibition on cruel and unusual punishment. The case Monday concerns the standards that states can use in defining who is disabled.
Hall is an illiterate 68-year-old high school dropout who has spent well over half his life in prison. His tested IQ has ranged as low as 60 and as high as 80. Most of his IQ test scores have hovered in the low 70s, well below the 100 average but slightly above Florida's strict threshold of 70 for determining intellectual disability.
Besides an IQ of 70 or below, Florida requires "deficits in adaptive behavior" and an onset before the age of 18 for those who claim intellectual disability. The court's focus Monday is strictly on the strict IQ score requirement, with Hall's supporters arguing that a test's margin of error should be taken into account. A margin of error means that someone might score 75 one day and 70 the next.
"Simply put, IQ test scores are not perfect measures of a person's intellectual ability," Hall's Tampa-based attorney, Eric Pinkard, and others wrote in a legal brief.
Mr. Pinkard and the rest of Hall's team, including former Clinton administration Solicitor General Seth Waxman, also stress other evidence for Hall's intellectual disability. Hall has poor short-term memory and a profound speech impediment. He cannot perform basic arithmetic, couldn't cook for himself while free and "could not understand adult conversation," the attorneys reported.
Mr. Waxman will argue on Hall's behalf Monday morning, having previously argued more than 65 times before the high court.
Florida has Idaho, South Carolina and seven other states on its side, arguing that the Supreme Court should give individual states "substantial leeway" in determining intellectual disability. If a state wants to set a strictly numerical IQ threshold as part of the assessment, as Florida has done, the high court shouldn't interfere, these officials say.
"Florida did not manufacture its IQ threshold out of thin air," Florida Attorney General Pam Bondi and Solicitor General Allen Winsor wrote in a legal brief, adding that the justices have "traditionally deferred to legislative judgments on scientific questions."
