What is the difference between insanity and incompetency?

• A. They are identical concepts.
• B. Incompetency relates to the mental state at the time of the crime.
• C. Insanity relates to the mental state at the time of the crime; incompetency relates to the state of mind at trial.
• D. Incompetency concerns only jury determination.

Answer: (C)

The key idea is about timing. Insanity looks at the defendant’s mental state at the time the crime occurred and, if proved, can negate criminal responsibility. Incompetency, or competence to stand trial, checks the defendant’s present ability to understand the proceedings and to work with counsel. If someone is incompetent, the trial is paused until they’re able to participate; if someone is insane at the moment of the offense, they may be found not guilty by reason of insanity and treated or confined for safety and treatment.
