In criminal law, mistake of fact and mistake of law are both defenses that can be used to exonerate criminal charges if deemed reasonable. To be convicted of relevant criminal charges the prosecution must prove beyond a reasonable doubt that the criminal defendant acted with criminal intent rather than as an honest mistake.
What is a mistake of fact and how can it be used as a defense?
Mistake of fact is commonly referred to as a mistaken belief or understanding of an individual that has led them to commit an illegal act unknowingly. To use mistake of fact as a defense, the defendant must disprove specific intent and/or disprove elements of the crime as material to the investigation.
