Moore v. Texas (U.S. Supreme Court, March 28/2017)

Moore was convicted of capital murder and sentenced to death. In post-trial proceedings, a circuit court concluded that Mr. Moore was intellectually disabled and, thus, ineligible for execution under Atkins v. Virginia, 536 U.S. 304 (2002) and Hall v. Florida, 572 U.S. ___ (2014). The circuit court based its decision on the most current medical guidelines. However, the Texas Court of Criminal Appeals (“CCA”) rejected that conclusion and re-instated Moore’s death sentence. The CCA concluded that the circuit court erred in not following factors laid out in Ex parte Briseno, 135 S. W. 3d 1( 2004), which relied upon medical authority from 1992. Moore appealed, claiming the CCA’s reasoning violated the Eighth Amendment.

REVERSED.

In Atkins, the Supreme Court opened the door to allow states to develop their own tests for determining intellectual disability and ineligibility for the death penalty. However, as the states have developed different tests, the Court has indicated it will review these procedures to determine whether the states have created “an unacceptable risk that persons with intellectual disability will be executed.” Hall v. Florida, 572 U.S. at ___. Here, the Court took aim at Texas’ Atkins test for determining intellectual disability which was centered around out-dated medical information and court-created “factors” that have been widely criticized.

In holding that Mr. Moore was ineligible for the death penalty under Atkins, the circuit court relied on medical diagnostic standards coming from the 11th edition of the American Association on Intellectual and Development Disabilities (“AAIDD”) clinical manual and the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (“DSM-5”) published by the American Psychiatric Association. The court followed the “generally accepted, uncontroversial intellectual-disability diagnostic definitions” in reaching their conclusion. Basically, the circuit court relied on the most up-to-date diagnostic material in assessing Moore.

The CCA rejected the circuit court’s conclusion and chastised it for not applying the Briseno test for determining intellectual disability. The Briseno test was based upon the 9th edition of the AAIDD and included a seven-factor test that was not grounded in any medical authority — just a judicial creation. The CCA recognized that the standards in the AAIDD may have changed, but concluded that the Briseno test “remained adequately informed by the medical community’s diagnostic framework.”

The Supreme Court concluded that the CCA’s reliance on out-dated medical information and “factors” that have been widely criticized and rejected in the legal and medical community could not comport with the Eighth Amendment as well as Atkins and Hall. While the State’s have leeway in formulating their own approach to addressing Atkins claims, the cornerstone of any scheme must be “the medical community’s diagnostic framework.”
