Predicting the present: expert testimony and civil commitment.
This article uses the Supreme Court's decision in Daubert as an opportunity to address a chronic concern regarding the disparity between mental health law as officially enunciated and the practical application of that law. After Daubert, admissibility of expert evidence under the federal rules requires a qualified expert, a reliable basis for the testimony, and relevance to the legal issue. Ongoing psychological research pursues empirical data that expands the scope of psychological expertise and clarifies its limits. This article addresses the requirement of relevance by examining the logical relationship between the psychologist's actuarial and clinical expertise and the legal issues addressed by the court in civil commitment proceedings. Ideally, Daubert might stimulate a process of cooperative analysis in which psychologists and lawyers clarify the proper roles of psychological experts and of the courts with which those experts interact. This article begins that project by clarifying the legal determination required in civil commitment proceedings and by explicating the relationship between the responsibilities of experts and those of courts.
