AZC20 v Secretary, Department of Home Affairs

In the case of AZC20 v Secretary, Department of Home Affairs, the High Court addressed an application for the disqualification of a judge due to concerns of apprehended bias. The applicant, AZC20, sought to disqualify the judge based on the fact that two of the respondents’ witnesses had previously given evidence in cases where the judge appeared as senior counsel, and that the judge had often represented the respondent parties. The dispute revolved around whether these circumstances created a reasonable apprehension of bias on the part of the judge.

The court needed to determine whether the judge's prior involvement in cases with the witnesses and representation of the respondents created a situation where a reasonable observer might apprehend that the judge might not deal with the case impartially. The legal principles surrounding judicial impartiality and the apprehension of bias were central to the decision. The court had to consider the nature of the judge's prior involvement and whether it could give rise to a reasonable apprehension of bias in the context of the current proceedings.

The High Court concluded that the circumstances did not create a reasonable apprehension of bias. The court found that the judge's prior representation of the respondents and appearance as counsel for two of the witnesses did not amount to a level of involvement that could lead a reasonable observer to question the judge's impartiality. The court was satisfied that the judge could approach the case with an open mind and without bias. Consequently, the application for disqualification was dismissed, and the matter was ordered to proceed to case management.
