"x x x.
The special civil action of quo warranto is a "prerogative writ by which the Government can call upon any person to show by what warrant he holds a public office or exercises a public franchise." 13 When the inquiry is focused on the legal existence of a body politic, the action is reserved to the State in a proceeding for quo warranto or any other credit proceeding. 14 It must be brought "in the name of the Republic of the Philippines" 15 and commenced by the Solicitor General or the fiscal "when directed by the President of the Philippines . . . ." 16 Such officers may, under certain circumstances, bring such an action "at the request and upon the relation of another person" with the permission of the court. 17 The Rules of Court also allows an individual to commence an action for quo warranto in his own name but this initiative can be done when he claims to be "entitled to a public office or position usurped or unlawfully held or exercised by another." 18 While the quo warranto proceedings filed below by petitioner municipality has so named only the officials of the Municipality of San Andres as respondents, it is virtually, however, a denunciation of the authority of the Municipality or Municipal District of San Andres to exist and to act in that capacity.
