Competency to stand trial refers to a defendant's ability to understand the legal proceedings against them and to participate in their own defense. This assessment ensures that individuals can comprehend the charges, the roles of the courtroom participants, and the potential consequences of their case. If a defendant is found incompetent, they may receive treatment to restore their competency. This process aims to help them gain the necessary understanding and skills to engage effectively in their trial. Ultimately, the goal is to ensure a fair legal process for all individuals involved.
