Forensic evaluators play a crucial role in determining a defendant's competency to stand trial, involving a comprehensive evaluation of their mental and cognitive abilities. Findings are presented in a written report submitted to the court, and the evaluator may also provide expert testimony. Competency to stand trial case law establishes that defendants must comprehend the legal proceedings against them and participate in their defense, and the court must raise concerns about competency if evidence of incompetence exists. In cases where medication is needed to restore competency, the court balances the defendant's liberty interest against the government's desire for a fair trial.
