Which test does the jury use to evaluate a defendant's mental state at the time of the offense?

• A. Ability to pay fines
• B. Substantial capacity to appreciate the criminality of conduct or to conform to the law
• C. Ability to assist counsel
• D. Knowledge of statutory law

Answer: (B)

Mental state at the time of the offense is evaluated by whether the defendant lacked substantial capacity to appreciate the criminality of conduct or to conform to the law because of a mental disease or defect. This substantial-capacity test, drawn from the Model Penal Code, asks the jury to consider both understanding that what they were doing was wrong and the ability to control their conduct to follow the law. If the mental condition prevented either capacity, the defendant may be found not guilty by reason of insanity. The other options don’t address the defendant’s mental state at the time of the offense: ability to pay fines relates to finances, ability to assist counsel concerns competency to stand trial, and knowledge of statutory law isn’t part of the insanity evaluation.
