delivered the opinion of the Court.
This is an original proceeding under C.A.R. 21, seeking relief in the nature of prohibition. The basis for the petition is the failure of the respondent City of Golden to join petitioners Western Paving Construction Co. and North Table Mountain Corporation in a petition for certiorari to review the action of the Jefferson County Board of Adjustment in issuing a special permit to extract rock, sand and gravel. Petitioners are the holders of that special permit. The cause proceeded to judgment without the joinder of petitioners, and the respondent court ordered the special permit revoked. Not being parties to the proceeding, petitioners sought relief *176in this court.
In Hennigh v. County Commissioners, 168 Colo. 128, 450 P.2d 73 (1969), we held that one whose application for a rezoning is challenged in court is an indispensable party to that proceeding. In Hidden Lake Development Co. v. District Court, 183 Colo. 168, 515 P.2d 632, we held that the failure to join an indispensable party rendered the judgment a nullity. For the reasons more completely discussed in Hidden Lake, the respondent court could not enter a valid judgment to deprive the petitioners of their permit without the presence of Western Paving Construction Co. and North Table Mountain Corporation. The judgment and the order revoking the special permit are of no legal force. The judgment must, therefore, be set aside. Respondent court is directed to vacate its order revoking the special permit and to dismiss the action.
The rule is made absolute.
