delivered the opinion of the Court.
This capital murder case is presently before this Court on remand from the Supreme Court of the United States.
Atkins
v.
Virginia,
The defendant, Daryl Renard Atkins, was convicted in the Circuit Court of York County of the capital murder of Eric Michael Nesbitt and was sentenced to death. We affirmed his conviction but remanded the case to the circuit court for a new penalty proceeding.
Atkins v. Commonwealth,
On appeal from the second penalty proceeding, Atkins argued, among other things, that this Court, as part of our proportionality review,
see
Code § 17.1-313(C), should commute his sentence of death to life imprisonment because he is mentally retarded.
Atkins II,
Thereafter, Atkins successfully petitioned the Supreme Court of the United States for a writ of certiorari.
Atkins
v.
Virginia,
Before addressing what further proceedings are necessary and would be consistent with the Supreme Court’s decision, we must first determine whether the Supreme Court decided that Atkins is, in fact, mentally retarded, thus requiring this Court to commute his sentence of death to life imprisonment. We conclude that the Supreme Court did not make that determination, nor has the question of Atkins’ mental retardation been answered at any point in his case.
In
Atkins II,
after summarizing the testimony of the two forensic clinical psychologists who testified at the re-sentencing hearing, we stated that the jury “heard extensive, but conflicting, testimony from [the psychologists] regarding Atkins’ mental retardation.”
The Supreme Court did, however, state that, “[t]o the extent there is serious disagreement about the execution of mentally retarded offenders, it is in determining which offenders are in fact retarded.”
Atkins III,
We also note that the jury at the re-sentencing hearing did not resolve the question of Atkins’ mental retardation. Pursuant to the provisions of Code § 19.2-264.4(B)(vi), the jury was required to consider evidence of mental retardation in mitigation of capital murder, but it was not required to make a definitive determination whether Atkins suffers from mental retardation. As we pointed out in
Atkins II,
the re-sentencing jury was instructed “to consider any evidence in mitigation of the offense, and the jury obviously found that Atkins’ IQ score did not mitigate his culpability for the murder of Nesbitt.”
Although Atkins acknowledges on brief that the Supreme Court did not make an explicit finding with regard to whether he suffers from mental retardation, he, nevertheless, argues that the Court implicitly concluded that he is mentally retarded. Otherwise, according to Atkins, he would not have had standing to raise the question whether the Eighth Amendment proscribes execution of a mentally retarded offender and the Supreme Court’s decision would be an advisory opinion. We do not agree.
In granting Atkins’ petition for a writ of certiorari, the Supreme Court decided to revisit the legal issue that it had previously considered in
Penry
and, accordingly, framed the issue as “[wjhether the execution of mentally retarded individuals convicted of capital crimes violates the Eighth Amendment[.]”
Atkins
v.
Virginia,
534
*78
U.S. 809 (2001) (amended order granting writ of certiorari). Atkins had standing to raise that constitutional issue because of the allegations, evidence, and argument presented in the circuit court, and on appeal to this Court, that he is mentally retarded. He demonstrated a “ ‘personal stake in the outcome!,]’ ” thereby “ ‘assuring] that concrete adverseness which sharpens the presentation of issues’ necessary for the proper resolution of constitutional questions.”
City of Los Angeles v. Lyons,
The Supreme Court resolved the legal issue by announcing a new rule of constitutional law and then remanded Atkins’ case to this Court for further proceedings not inconsistent with that new rule. Since the controverted factual question whether Atkins suffers from mental retardation has never been resolved, any further proceeding, consistent with the Supreme Court’s remand, must be one in which that question is answered and the Eighth Amendment prohibition against the execution of mentally retarded offenders is applied to that factual determination. Such a proceeding will not render the Supreme Court’s decision in Atkins III advisory but will implement that decision. 3
The Supreme Court’s remand in this case is procedurally similar to the remand in
Ford v. Wainwright.
There, the Supreme Court held that the Eighth Amendment prohibits a State from executing an insane prisoner.
Turning now to consider what type of proceeding is necessary and consistent with the Supreme Court’s opinion, we note that the General Assembly, in response to the Supreme Court’s giving to the States the task of developing an appropriate way to enforce its constitutional restriction on the execution of the death penalty, enacted emergency legislation that is already effective. See Code §§ 8.01-654.2, 18.2-10, 19.2-175, 19.2-264.3:1, 19.2-264.3:1.1, 19.2-264.3:1.2, 19.2-264.3:3, and 19.2-264.4. In that legislation, the General Assembly, among other things, defined the term “mentally retarded.”
“Mentally retarded” means a disability, originating before the age of 18 years, characterized concurrently by (i) significantly subaverage intellectual functioning as demonstrated by performance on a standardized measure of intellectual functioning administered in conformity with accepted professional practice, that is at least two standard deviations below the mean and (ii) significant limitations in adaptive behavior as expressed in conceptual, social and practical adaptive skills.
Code § 19.2-264.3:1.1(A). The General Assembly also provided that a defendant has the burden of proving mental retardation by a preponderance of the evidence. Code § 19.2-264.3:1.1(C).
In light of this legislation, which is applicable to Atkins’ case,
see
Code § 8.01-654.2, the Supreme Court’s mandate requiring further proceedings not inconsistent with its opinion, and the fact that the question of Atkins’ mental retardation has never been answered, we conclude that this case must be remanded to the Circuit Court of York County for a hearing on the sole issue of whether Atkins is mentally retarded as defined in Code § 19.2-264.3:1.1(A). In accordance with the provisions of Code § 8.01-654.2, which require this Court to consider a claim of mental retardation presented by a person sentenced to death before the effective date of the emergency legislation and to determine whether the claim is frivolous, and upon reviewing the evidence of mental retardation presented at the re-sentencing hearing in
Atkins II,
Thus, we will remand this case to the circuit court for further proceedings consistent with this opinion and with the opinion of the Supreme Court in Atkins III.
Remanded.
Notes
Atkins II
was decided by a divided Court.
Atkins II,
Our conclusion is not altered by the Commonwealth’s argument on brief in the Supreme Court that Atkins is not a mentally retarded individual and that, therefore, any decision by that Court would be an advisory opinion. The Court obviously rejected the Commonwealth’s position but, in its role as an appellate court, did not resolve the underlying disputed factual issue regarding Atkins’ mental retardation.
