Lex Aquilia is a Latin term which means “Aquilian law.” This is a Roman statute imposing liability for pecuniary losses caused tortiously. In short, it provided compensation to the owners of property injured by someone's fault. It generally regulated loss caused by damage to property, and included compensation that is to be paid for injury caused to another's slave or livestock. However the loss caused should be financially measurable and caused wrongfully. If the liable party denied liability, then damages were doubled. This law applied to negligence as well as willful injury. This law was enacted around 287 b.c., and it superseded the earlier provisions of the Twelve Tables.
