Australian Catholic BishopsConference & Anor, Ex Parte the Hon Justice Sundberg C21/2000

The applicants, the Australian Catholic Bishops Conference and the Catholic Education Office of the Catholic Archdiocese of Melbourne, sought an order of prohibition against the Hon Justice Sundberg, a judge of the Federal Court of Australia. The applicants sought to prevent Justice Sundberg from continuing to hear and determine proceedings in the Federal Court, specifically concerning allegations of discrimination against them.

The central legal issue before Callinan J was whether Justice Sundberg had demonstrated a reasonable apprehension of bias, thereby disqualifying him from presiding over the discrimination proceedings. This required an examination of whether a fair-minded lay observer, knowing the relevant facts, would apprehend that Justice Sundberg might not bring an impartial mind to the resolution of the case.

Callinan J considered the applicants' submissions that Justice Sundberg's prior involvement in a related matter, where he had made comments about the Catholic Church's stance on certain social issues, gave rise to a reasonable apprehension of bias. However, Callinan J found that the context of Justice Sundberg's previous remarks did not demonstrate actual bias or a predisposition that would prevent him from impartially considering the evidence in the current proceedings. The judge concluded that the apprehension of bias was not made out, and therefore, the application for prohibition was dismissed.
