Broadly stated, the quo warranto proceeding affords a judicial enquiry in which any person holding an independent substantive public office, or franchise, or liberty, is called upon to show by what right he holds the said office, franchise or liberty; if the inquiry leads to the finding that the holder of the office has no valid title to it, the issue of the writ of quo warranto ousts him from that office. In other words, the procedure of quo warranto confers jurisdiction and authority on the judiciary to control executive action in the matter of making appointments to public offices against the relevant statutory provisions; it also protects a citizen from being deprived of public office to which he may have a right. It would thus be seen that if these proceedings are adopted subject to the conditions recognised in that behalf, they tend to protect the public from usurpers of public office; in some cases, persons, not entitled to public office may be allowed to occupy them and to continue to hold them as a result of the connivance of the executive or with its active help, and in such cases, if the jurisdiction of the courts to issue writ of quo warranto is properly invoked, the usurper can be ousted and the person entitled to the post allowed to occupy it. It is thus clear that before a citizen can claim a writ of quo warranto, he must satisfy the court, inter alia, that the office in question is a public office and is held by usurper without legal authority, and that necessarily leads to the enquiry as to whether the appointment of the said alleged usurper has been made in accordance with law or not."
