Ausn Catholic Bishops Conf & Anor, Ex parte - Re Sundberg

The Australian Catholic Bishops Conference and the Catholic Education Office of the Archdiocese of Sydney sought judicial review of a decision made by the respondent, Mr. Sundberg, in his capacity as the Registrar of the Industrial Relations Commission of New South Wales. The applicants challenged the Registrar's determination that certain teachers employed by Catholic systemic schools were entitled to a loading for the performance of duties outside of school hours, specifically for the preparation and marking of student work.

The central legal issue before the High Court of Australia was whether the Registrar's determination, which purported to grant an additional loading to teachers for work performed outside of ordinary school hours, was valid. This involved considering the scope of the Registrar's powers under the relevant industrial legislation and whether the determination constituted an impermissible encroachment on the functions of the employer, the Catholic school authorities, in managing their staff and educational operations.

The High Court held that the Registrar had exceeded his statutory authority. The Court reasoned that the power to determine terms and conditions of employment did not extend to dictating how an employer should manage its workforce or to mandating specific payments for tasks that were inherently part of a teacher's professional responsibilities, such as preparation and marking. Such matters were considered to fall within the managerial prerogative of the employer, subject to general principles of industrial law and any express provisions in an award or agreement. The Court found that the Registrar's determination was an unwarranted interference with this prerogative and was therefore invalid.
