Public Service Association of South Australia v Federated Clerks Union of Australia South Australia Branch

The parties to this proceeding before the High Court of Australia were the Public Service Association of South Australia and the Federated Clerks Union of Australia South Australian Branch, along with the Australian Social Welfare Union. The dispute concerned the interpretation of section 121(5) of an unspecified Act, specifically the extent to which its opening words, "may refuse if," conferred a discretion upon the Industrial Registrar. The respondent argued that the Supreme Court of South Australia's interpretation of this provision was correct.

The central legal issue before the High Court was the nature and scope of the discretion vested in the Industrial Registrar by section 121(5). Specifically, the court was required to determine whether the Registrar possessed a discretion to refuse an application if none of the grounds specified in paragraphs (a), (b), or (c) of the subsection were made out. This involved considering whether the formation of an opinion by the Registrar under paragraph (a) constituted a discretionary judgment.

The court was presented with the argument that the Supreme Court of South Australia had correctly interpreted section 121(5) to mean that the Registrar's discretion to refuse an application only arose if one or more of the grounds listed in paragraphs (a), (b), or (c) were established. If these grounds were not made out, then, according to this interpretation, the Registrar had no discretion to refuse, and the applicant was entitled to have the rule alteration made. The respondent contended that the words "may refuse if" meant that if the specified grounds were not met, the discretion to refuse was irrelevant, and the case for exercising such discretion never arose.
