What are crimes that do not require mens rea commonly known as?

Crimes that do not require mens rea, or the intention to commit a crime, are known as strict liability crimes. In these types of offenses, the prosecution does not need to prove that the defendant had any intent or mental state at the time of the crime; rather, the mere act of committing the prohibited action is enough for liability. This legal principle is often applied in regulatory offenses, such as violations of traffic laws or environmental regulations, where the law prioritizes public safety or welfare over the individual's intent.

Strict liability is especially crucial in contexts where the potential harm to society is significant, allowing the legal system to hold individuals accountable regardless of their mindset when committing the offense. This approach helps to deter harmful actions and ensures compliance with laws designed to protect public interests.
