In Matter of Registrant C.A., 146 N.J. 71, 679 A.2d 1153 (1996), the Court held that the RRAS "is an appropriate and reliable tool" whose use is consistent with the requirements of the statutes and case law. Id. at 107, 679 A.2d 1153. Although C.A. involved a proceeding where the rules of evidence did not apply, the Court's reasoning in C.A. is instructive as to its view of actuarial instruments in general. After reviewing the development of the RRAS, the Court stated that although the weights assigned to the categories in the RRAS Scale have not been scientifically proven to be valid, the State has produced sufficient evidence to convince us that the factors used in the Scale are reliable predictors of recidivism and are weighted in the Scale according to their relative effectiveness as predictors. The greater weight attached to the static categories is in accord with expert opinion on criminal sexual behavior. Id. at 105, 679 A.2d 1153. Most important, the Court stated that scientific literature has shown "that the use of actuarial concrete predictors is at least as good, if not in most cases better, in terms of reliability and predictability than clinical interviews." Id. at 106, 679 A.2d 1153. Although C.A. argued that the RRAS was unreliable, untested, and arbitrary in operation, and the Court agreed that the RRAS had not been empirically validated through scientific field studies, the Court nevertheless found that the factors which comprise the RRAS "have been shown to be the best indicators of risk of re-offense." Id. at 107, 679 A.2d 1153. The Court further observed that "one of the great strengths of the RRAS is that it can provide consistent measures of risk of re-offense." Id. at 108, 679 A.2d 1153. Finally, the Court observed that the RRAS "is not a scientific device. It is merely a useful tool to help prosecutors and courts determine whether a registrant's risk of reoffense is low, high, or moderate." Ibid.
