title: Hall v. Florida: Capital Punishment, IQ, and Persons With Intellectual Disabilities.
abstract: The United States Supreme Court has ruled on the question of persons with intellectual disability and capital punishment in several notable cases, including Penry v. Lynaugh (1989) and Atkins v. Virginia (2002). In 2014, the U.S. Supreme Court revisited the subject in Hall v. Florida. Although Florida Statute § 921.137 prohibits imposing a sentence of death on a defendant convicted of a capital felony if it is determined that the defendant is intellectually disabled, the Florida Supreme Court strictly interpreted the law so that, because Mr. Hall's IQ was not below the cutoff of 70, further evidence could not be presented to show that he had an intellectual disability. In Hall v. Florida, the Court analyzed the relevance of the standard error of measurement of IQ testing, whether there is a consensus among the states regarding capital punishment, and whether there is a consensus among professional associations regarding these questions. The Court also adopted the term "intellectual disability" as opposed to "mental retardation," following changes in both the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and the U.S. Code and Code of Federal Regulations. We examine the Court's decision and offer commentary regarding the overall effect of this landmark case.
