Australian Catholic Bishops Conference & Ors, Ex parte - Re Sundberg & Anor

The High Court of Australia considered an application for a writ of prohibition by the Australian Catholic Bishops Conference and others, seeking to prevent the respondent, Sundberg J, from continuing to hear proceedings in the Federal Court of Australia. The applicants sought to prohibit Justice Sundberg from hearing a case concerning alleged discrimination against a former employee of the Catholic Education Office of the Catholic Archdiocese of Melbourne.

The central legal issue before the High Court was whether Justice Sundberg had demonstrated a reasonable apprehension of bias, thereby disqualifying him from presiding over the discrimination proceedings. This question arose from Justice Sundberg's prior involvement in a separate matter where he had made observations about the Catholic Church's employment practices, which the applicants argued indicated a predisposition against them.

The High Court applied the established test for apprehended bias, which requires an objective assessment of whether a fair-minded lay observer, knowing the relevant facts, would apprehend that the judge might not bring an impartial mind to the issues before them. Gleeson CJ, Gummow and Hayne JJ found that while Justice Sundberg's previous comments were unfortunate and potentially ill-advised, they did not, when viewed objectively and in context, demonstrate a predisposition that would lead a fair-minded observer to apprehend bias. The court emphasised that judges are expected to bring their legal knowledge and experience to bear on cases, and isolated remarks made in a different context should not automatically lead to disqualification.

The application for a writ of prohibition was dismissed.
