Ex Maleficio Non Oritur Contractus Law and Legal Definition

Ex maleficio non oritur contractus is a Latin maxim which means ‘a contract cannot arise out of an act radically vicious and illegal’. A contract or an agreement cannot be made the subject of an action if it be impeachable on the ground of dishonesty, as being opposed to public policy, or forbidden by the law. [Pope v. Standard Oil Co., 13 Ohio Dec. 751, 752 (Ohio C.P. 1903)]
