Mistake of Fact
CL: Defense to specific intent even if unreasonable. Defense to general intent/malice if reasonable
MPC: serves as defense if it prevents prosecution from establishing required state of mind for material elements of crime
Strict liability: No defense
Mistake of law

- Honestly held mistake of law negates required intent or mental state
- D relied on court decision/administrative order or official interpretation
