Quo Warranto

A legal proceeding during which an individual's right to hold an office or governmental privilege is challenged.

In old English practice, the writ of quo warranto—an order issued by authority of the king—was one of the most ancient and important writs. It has not, however, been used for centuries, since the procedure and effect of the judgment were so impractical.

Currently the former procedure has been replaced by an information in the nature of a quo warranto, an extraordinary remedy by which a prosecuting attorney, who represents the public at large, challenges someone who has usurped a public office or someone who, through abuse or neglect, has forfeited an office to which she was entitled. In spite of the fact that the remedy of quo warranto is pursued by a prosecuting attorney in a majority of jurisdictions, it is ordinarily regarded as a civil rather than criminal action. Quo warranto is often the only proper legal remedy; however, the legislature can enact legislation or provide other forms of relief.
