The Industrial Court is constituted under The Industrial Conciliation and Arbitration Acts 1932 to 1955 Q.. On 17th December 1952 there was published in the Government Gazette an award described as the " Garage and Service Station Attendants' Award - Southern Division (Eastern District) ". This award dealt with wages, hours of work, overtime, sick leave, and a large number of other matters affecting the relations of employers and employees. Clause 5 was headed "Restriction of Hours for selling Petrol", and was in the following terms: - "It shall not be lawful in the Factories and Shops District of Brisbane for any occupier of a garage and/or service station to sell, issue, or deliver petrol, motor spirit, motor fuel, or substitutes therefor, and/or motor oil, or permit any employee or other person to do so before 7 a.m. or after 6 p.m. Mondays to Fridays inclusive, and before 7 a.m. or after 2 p.m. on Saturdays, or at all on a Sunday, Christmas Day, Anzac Day, or Good Fridays". This award was varied in immaterial respects on 31st July 1957 and 26th October 1957. On 26th October 1957 a notice of motion for a further variation was filed in the Industrial Court on behalf of the Royal Automobile Club of Queensland, the Queensland Automobile Chamber of Commerce Incorporated Union of Employers, the members of the Service Station Association of Queensland, and The Federated Miscellaneous Workers' Union of Employees, Queensland Branch. The motion was supported by an affidavit which stated that agreement as to the variation sought had been reached between the above-named bodies and the Minister for Labour and Industry. On 1st November 1957 the court made the variation sought, and its order was published in the Government Gazette of 19th November 1957. The text was headed: "In the matter of" the Award, and "In the matter of an application by the Royal Automobile Club of Queensland, the Queensland Automobile Chamber of Commerce Incorporated Union of Employers, the Members of the Service Station Association of Queensland and the Federated Miscellaneous Workers' Union of Employees of Australia, Queensland Branch for a variation of the said Award." Then came the following recital: - "This matter coming on for hearing before the Court at Brisbane on 1st November, 1957: This Court, after hearing Mr. K. C. Shaw for the Royal Automobile Club of Queensland; Mr. J. P. Coneybeer for the Queensland Automobile Chamber of Commerce Incorporated Union of Employers; Mr. A. H. Smout for The Service Station Association of Queensland; and Mr. W. T. Ward for the Federated Miscellaneous Workers' Union of Employees of Australia, Queensland Branch, doth order, by consent, that the said Award be varied as follows as from the fourth day of November 1957: - " The relevant variation was made "by deleting clause 5 and inserting the following in lieu thereof:" The actual restrictions on the hours for selling petrol etc. were the same as had been prescribed by the old cl. 5, but the new cl. 5 added elaborate provisions for the zoning of the district and the rostering of a limited number of traders in each zone to sell petrol etc. on Saturday afternoons and Sundays. The court ordered that the award as varied be consolidated and reprinted. In pursuance of this order a consolidated award was published in the Gazette of 19th November 1957. Clause 26 of the consolidated award is in the following terms: - "26. This Award as consolidated and reprinted shall take effect and have the force of law throughout the area specified as from the fourth day of November 1957, and shall remain in force for a period of twelve months from the date hereof."
