mens rea

  • /ˌmɛnz ˈɹiːə/

Rhymes with -iːə

Where it comes from

From Latin mēns + reus (literally “guilty mind”), from the English common law precept Actus non facit reum nisi mens rea sit ("The act does not make a person guilty unless the mind is also guilty").

noun mentes reae

  1. general A reactive mind, a conscious knowing by the individual that an act was committed, either by oneself or by another.
  2. A guilty mind, the conscious knowing of a perpetrator while committing an act that the act is illicit. As a general rule the act (or omission) causing death and the relevant mens rea must occur at the same time. The most obvious application of this rule to exclude liability is the case where the mens rea is formed after the actus reus has taken place.
