An accusation is informally stating that a person has committed an illegal or immoral act. An accusation is also formally charging a person with a crime either by a prosecuting attorney filing charges against or through a grand jury indictment of that person.
See, e.g. Rothgery v. Gillespie County, Tex., 554 U.S. 191 (2008) and U.S. v. Patterson, 150 U.S. 65 (1893).
