A Dictionary of Law
A misdeed or trespass. The doing what a party ought to do improperly, 1 Tidd, Pr. 4. The improper performance of some act which a man may lawfully do.
3 Steph. Comm. 460.
Misfeasanece, strictly, is not doing a lawful act in a proper manner, omitting to do it as it should be done; while malfeasance is the doing an act wholly wrongful; and aon-feasance is an omission to perform a duty, or a total neglect of duty. But “mmisfeasauce” is often carelessly used in the sense of “malfeasance.”
