On November 29, 2016, the Supreme Court heard oral argument in Moore v. Texas. In 1980, Bobby James Moore was convicted of capital murder for the shooting of James McCarble, a seventy-year-old store clerk, in Houston, Texas. Moore was convicted and received a death sentence, which was affirmed on appeal. After a federal court granted habeas corpus relief, a new punishment hearing occurred in 2001, and Moore was again sentenced to the death penalty. His sentence was again affirmed on appeal. Moore sought state habeas relief and argued that, under the U.S. Supreme Court’s 2002 decision in Atkins v. Virginia he was exempt from execution, because he was intellectually disabled. The state court granted habeas relief based on Moore’s Atkins argument, applying a definition of intellectual disability used by the American Association on Intellectual and Developmental Disabilities (AAIDD). The Court of Criminal Appeals of Texas reversed the grant, noting that the Texas legislature had not yet passed Atkins legislation and that the AAIDD definition of intellectual disability diverged from that previously adopted by Texas courts in the wake of Atkins--a 1992 definition used by AAIDD’s predecessor the American Association on Mental Retardation (AAMR), as well as the Texas Health and Safety Code. Moore, the Court of Criminal Appeals held, ultimately failed to establish by a preponderance of the evidence that he was intellectually disabled within the meaning of Atkins, as applied by Texas courts. -- The question before the U.S. Supreme Court is whether it violates the Eighth Amendment and the Court’s decisions in Hall v. Florida and Atkins v. Virginia to prohibit the use of current medical standards on intellectual disability, and require the use of outdated medical standards, in determining whether an individual may be executed. -- To discuss the case, we have Kent S. Scheidegger who is Legal Director and General Counsel for the Criminal Justice Legal Foundation.
