¶1dissenting in part.
¶2Today Georgia stands alone in severely inhibiting Eighth Amendment protections by applying the most stringent standard available in our system of justice — requiring a capital defendant to prove his or her mental retardation “beyond a reasonable doubt.” OCGA § 17-7-131 (c) (3). The execution of mentally retarded offenders was declared unconstitutional by the Supreme Court of the United States under Atkins v. Virginia, 536 U. S. 304, 318-321 (122 SC 2242, 153 LE2d 335) (2002) (justifying the categorical prohibition against the execution of mentally retarded offenders on the grounds that the death penalty will not further either the penal goal of retribution or deterrence and because “[mjentally retarded defendants in the aggregate face a special risk of wrongful execution”). In finding such executions constitute “cruel and unusual punishment,” the Court recognized a “national consensus” in favor of excluding mentally retarded offenders from the death penalty and expressly directed the States to “ develop [ ] appropriate ways to enforce the constitutional restriction upon [their] execution of sentences.” Id. at 317 (quoting Ford v. Wainwright, 477 U. S. 399, 416-417 (106 SC 2595, 91 LE2d 335) (1986)). Although the Supreme Court did not explicitly distinguish between “appropriate” and inappropriate means to identify mentally retarded offenders, the Court did justify the categorical exclusion in part on the inherent difficulties mentally retarded offenders face during a criminal trial. Atkins, supra,536 U. S. at 320-321 (“The risk [of an unwarranted death penalty] is enhanced [because] .. . [m]entally retarded defendants may be less able to give meaningful assistance to their counsel and are typically poor witnesses, and their demeanor may create an unwarranted impression of lack of remorse for their crimes.”). Georgia’s requirement that mental retardation be proven beyond a reasonable doubt is too rigorous a standard to sufficiently uphold this constitutional protection. In reality, the result of this standard is essentially an insurmountable hurdle for defendants. Its use in criminal trials ignores the justification at the heart of the Atkinsholding, as mentally retarded offenders may be sentenced to death — despite a vastly disproportionate amount of evidence in their favor — for reasons which may be beyond their control. As stated in the dissent of Head v. Hill, which I joined, “Georgia’s statute . . . do[es] not prohibit the [Sjtate from executing mentally retarded people. To the contrary, the State may still execute people who are in all probability mentally retarded[,] . . . more than likely mentally retarded[,] . . . *378[and] even . . . almost certainly mentally retarded.” Head v. Hill, 277 Ga. 255, 274 (587 SE2d 613) (2003) (4-3 decision). To actively promote this outcome amounts to an unfettered abuse of discretion in violation of the Constitution.
¶3Of the 30 states that impose the death penalty, 22 have adopted a preponderance of the evidence standard for proving mental retardation.
¶4 Alabama, Arkansas, California, Idaho, Indiana, Louisiana, Maryland, Mississippi, Missouri, Nebraska, Nevada, New Mexico, New York, North Carolina, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Utah, Virginia, and Washington require an offender to prove mental retardation by a preponderance of the evidence. Four states - Arizona, Colorado, Florida, and Delaware - require clear and convincing evidence and three states - Connecticut, Kansas, and Kentucky - have not set a standard of proof for mentally retarded offenders.
¶5 With the enactment of OCGA § 17-7-131 (j) in 1988, Georgia was the first state in the nation to ban the execution of mentally retarded defendants. The AtkinsCourt acknowledged Georgia’s pioneering in this area in reference to the “national consensus” to prohibit executions of mentally retarded people. Atkins, 536 U. S. at 313-316. The Court did not, however, express that Georgia’s reasonable-doubt standard would be sufficient to uphold Eighth Amendment protections and the new federal ban resulting from the Atkinsholding.
