We granted this interlocutory appeal to determine whether the trial court was correct in ruling that in a triаl on the issue of the defendant’s mental retardation pursuant to
Fleming v. Zant,
In 1988, we affirmed Patillo’s conviction and death penalty.
Patillo v. State,
The state appeals, contending that in order to test the credibility of experts and others who will offer opinion evidence about Patillo’s mental capacity, the state should be permitted to cross-examine those witnesses about their personal beliefs concerning the death penalty and about their personal interests in the penalty which may be imposed. Patillo responds that the credibility of his witnesses may adequately be evaluated without diverting the jury’s attention away from its duty to decide objectively the issue of mental retardation by injecting issues about the appropriateness of a death penalty.
We note that in trials under OCGA § 17-7-131 (j), the issue of mental retardation is decided at the guilt phase of the trial. At this phase of the trial, it is “generally accepted” that prosecutors should not “ ‘divert the jury from its duty to decide the сase on the evidence ... by making predictions of the consequences of the jury’s verdict.’ [Cit.]”
Walker v. State,
It may be true, as the state contends, that the consequences of the jury’s verdict in a
Fleming
trial on mental retardation are not irrelevant to an evaluation of the credibility of the defendant’s witnesses. For example, if a mental health expert, conscientiously op

posed to the death penalty knows that the death sentence in this case will be vacated if Patillo is found to be mentally retarded, the expert’s opposition to the death penalty might — consciously or unconsciously — affect his testimony and conclusions. But, as we have recognized, relevant evidence mаy sometimes be excluded where its probative value is small and the risk of prejudice great. See
Hicks v. State,
Judgment affirmed.
Notes
It follows from the foregoing that, except in exceptional circumstances, it will not be necessary or appropriate to qualify the jury under
Witherspoon v. Illinois,
