This legal principle means “An act does not make a person guilty unless there is a guilty mind.” It emphasizes the importance of both the physical act (actus reus) and the mental intent (mens rea) in establishing criminal liability.
In criminal law, for a person to be held liable for an offense, it is necessary to prove both the wrongful act and the guilty intention behind it.
Conclusion:
The full maxim is “Actus non facit reum nisi mens sit rea”, highlighting the requirement of both act and intent for criminal guilt.
