ON 9 AUGUST 1949, the High Court of Australia delivered R v Commonwealth Court of Conciliation & Arbitration; Ex parte Ozone Theatres (Aust) Ltd  HCA 33; (1949) 78 CLR 389 (9 August 1949).
A court has a discretion to withhold the granting of a writ of mandamus:
“For example the writ may not be granted if a more convenient and satisfactory remedy exists, if no useful result could ensue, if the party has been guilty of unwarrantable delay or if there has been bad faith on the part of the applicant, either in the transaction out of which the duty to be enforced arises or towards the court to which the application is made. The court’s discretion is judicial and if the refusal of a definite public duty is established, the writ issues unless circumstances appear making it just that the remedy should be withheld.” (at 400).
