Mistake of fact may be a defense when it negates a material element of the crime. It is not limited to a particular type of case, whether felony or misdemeanor, and it does not need to be coupled with a mistake of law. Mistake of fact can be a defense when it negates a material element of the crime, meaning that the mistake prevented the defendant from having the mens rea (criminal intent) required for the crime.
