Competence to Stand Trial and the Insanity Defense

In criminal proceedings, the mental state of the defendant is critically important to two distinct aspects of the proceedings. It is most often relevant to the fundamental issue of basic due process rights, and in certain cases, questions of criminal responsibility. The forensic psychiatrist utilizes expert knowledge and techniques to provide an examination of the defendant’s mental state to aid the court in making determinations in these critical areas. The defendant’s mental state during the criminal proceedings is relevant to their competence to stand trial, whereas separately their mental state at the time of the offense is relevant to insanity and questions of criminal responsibility.
