century law firm legal maxim actus reus

Term- actus reus

Translation- guilty act

Definition- Part of what proves criminal liability (with mens rea)

Actus reus is a Latin term that translates to “guilty act.” It is a fundamental concept in criminal law and refers to the physical or external element of a crime.

In order for a crime to have been committed, there must be both actus reus and mens rea, which refers to the mental state or intention of the person committing the act. Actus reus refers specifically to the physical or external action that constitutes the crime.

For example, if someone is accused of stealing, the actus reus would be the actual act of taking someone else’s property without permission. However, in order to establish guilt, it must also be shown that the person had the necessary mens rea, such as the intent to permanently deprive the owner of their property.

In some cases, actus reus may also include a failure to act or omission. For example, if someone is legally required to report an accident or emergency, and they fail to do so, they may be charged with a crime based on their failure to act.

Overall, actus reus is an important concept in criminal law as it establishes the physical element of a crime that must be proven in order to establish guilt. Without actus reus, there can be no crime, even if there is evidence of mens rea.
