Mistake of fact can be a defense for which crimes?

• A. A defense for strict liability crimes
• B. A defense for general and specific intent crimes
• C. Not a defense for any crime
• D. A defense only when the defendant was intoxicated

Answer: (B)

Mistake of fact acts as a defense whenever the crime requires a mental state and the defendant’s mistaken belief about a fact negates that state. If the law requires only a general awareness of acting in a prohibited way, a true misunderstanding about a fact can still defeat the necessary intent. If the offense requires a specific aim or purpose beyond the act itself, the mistaken belief that prevented forming that specific intent can likewise defeat the crime. But for strict liability offenses, no mental state is needed, so a mistake about facts doesn’t excuse the conduct. And the question isn’t about intoxication, which involves a different line of defense related to the defendant’s state of mind rather than a mistaken belief about facts. So mistake of fact best applies to crimes that require either general or specific intent.
