Malfeasance in office is any unlawful conduct that is often grounds for a just cause removal of an elected official by statute or recall election, or even additionally a crime. Malfeasance in office contrasts with "misfeasance in office", which is the commission of a lawful act, done in an official capacity, that improperly causes harm; and "nonfeasance in office", which is the failure to perform an official duty.
An exact definition of malfeasance in office is difficult: many highly regarded secondary sources (such as books and commentaries) compete over its established elements based on reported cases. This confusion has arisen from the courts where no single consensus definition has arisen from the relatively few reported appeal-level cases involving malfeasance in office.
