A writ of Quo Warranto is issued by a court to inquire into the legality of the claim of a person to a public office. A necessary condition for issuing this writ is that the office must be a *substantive* public office of a permanent character, created by statute or the Constitution. The office must not be merely ministerial or temporary. Therefore, the statement that “The office must not be a substantive one” is incorrect and is *not* a necessary condition.
The purpose of Quo Warranto is to prevent illegal usurpation of public office by a person.
Other necessary conditions for the issue of Quo Warranto are that the office must be a public office, it must be created by a statute or the Constitution, and the person holding the office must have entered it in contravention of the law. The applicant for the writ does not have to be the aggrieved party or claimant to the office; any person can apply.
