being unconstitutionally vague: When a law does not specifically enumerate the practices that are either required or prohibited. In this case, the ordinary citizen does not know what the law requires. See also Coates v. City of Cincinnati (1971) and FCC v. Fox Television Stations, Inc (2012). When a law does not specifically detail the procedure followed by officers or judges of the law. As a guard, a law must particularly detail what officers are to do, providing both for what they must do and what they must not do. Under the doctrine, judges must have a clear understanding of how they are to approach and handle a case. See also Kolender v. Lawson (1983). Both scienter and objective criteria that specify the harm to be protected against are necessary to limit vagueness in criminal statutes (Compare page 9 of ). To satisfy the Due Process Clause of the Fifth Amendment, individuals are entitled to understand the scope and nature of statutes which might subject them to criminal penalties. Thus, in Skilling v. United States (2010), it was held that a "penal statute must define the criminal offense (1) with sufficient definiteness that ordinary people can understand what conduct is prohibited and (2) in a manner that does not encourage arbitrary and discriminatory enforcement." Unconstitutional vagueness Unconstitutional vagueness is a concept that is used to strike down certain laws and judicial actions in United States federal courts. It is derived from the due process doctrine found in the Fifth and Fourteenth Amendments to the United States Constitution. The doctrine prohibits criminal prosecution for laws where it is impossible to reasonably understand what conduct is prohibited. Examples of unconstitutional vagueness The Florida Supreme Court, in Franklin v. State (Fla. 1971), ruled that the state's felony ban on sodomy was unconstitutionally vague because an "average person of common intelligence" could not reasonably know, without speculating, whether "abominable and detestable crime against nature" included oral sex or only anal sex. Papachristou v. Jacksonville (1972) and Kolender v. Lawson (1983) were two U.S. Supreme Court cases where the court struck down laws against vagrancy for unconstitutional vagueness; in restricting activities like "loafing", "strolling", or "wandering around from place to place", the law gave arbitrary power to the police and, since people could not reasonably know what sort of conduct is forbidden under the law, could potentially criminalize innocuous everyday activities.
