Competency to Stand Trial refers to a legal standard used to determine if a defendant is mentally capable of understanding the charges against them and can participate in their own defense. This assessment ensures that individuals are not tried for crimes if they cannot comprehend the proceedings or assist their attorneys due to mental illness or cognitive impairment. The evaluation process typically involves mental health professionals who assess the defendant's understanding of the legal system, their ability to communicate with their lawyer, and their grasp of the consequences of the trial. If found incompetent, the defendant may receive treatment until they can be deemed competent to stand trial.
