COMMON LAW: Mistake of fact
MPC: Mistake of Fact
General: The first step in analyzing a mistake of fact claim in a common law jurisdiction is to identify the nature of the crime as either strict liability, specific intent, or general intent.
Specific Intent: Δ not guilty if mistake of fact negates the specific intent of crime
General Intent: Δ guilty if mistake of fact was unreasonable; Reasonable mistake is usually defense.
Strict Liability: mistake of fact never a defense
General: Uses a straightforward elemental approach to matters of mens rea, including mistakes of fact.
Specifically as to mistakes of fact, 2.04(1) provides that a mistake is a defense if it negates the mental state required to establish any element of the offense. It is irrelevant whether the offense would be identified as general-intent or specific-intent at common law.
