putativus

Putativus is a Latin term used in legal contexts, particularly in criminal law, to describe a belief that is honestly held but factually incorrect. It is often translated as "supposed" or "believed" and refers to a state of mind. For example, a putativus defense might arise when a person acts in self-defense based on a mistaken but reasonable belief that they were in imminent danger. The key element is that the belief, though wrong, was subjectively genuine and, in some legal systems, objectively reasonable. This concept is important in determining criminal liability, as it can negate the mens rea or criminal intent required for certain offenses. The legal system distinguishes between a putativus mistake and a mistake of law, which is generally not a valid defense. The application of the putativus principle varies across jurisdictions, with some requiring the mistaken belief to be not only honest but also reasonable, while others focus more heavily on the subjective honesty of the belief. Understanding putativus is crucial for analyzing defenses that rely on a mistaken understanding of the facts.
