The opinion of the court was delivered by

The relator attempts to have us review an order of the Supreme Court discharging a rule to show cause why mandamus should not issue to compel the issuance of a building permit and a license for the erection of a gasoline service station.

Since the constitutionality of a statute is not involved, the Supreme Court’s refusal of mandamus is not reviewable in this court. Matlack v. Lloyd, 82 N. J. L. 739; Camden v. Public Service Railway Co., 84 Id. 309.

The appeal must be dismissed.

For dismissal — The Chancellor, Chief Justice, Trenohard, Case, Bodine, Donges, Perskie, Van Buskirk, Kays, Heteield, Dear, Wells, Dill, JJ. 13.
