Kirby v Dental Council of New South Wales

In Kirby v Dental Council of New South Wales, the respondent, a registered dentist, appealed against decisions of the Civil and Administrative Tribunal (CAT) dismissing appeals against decisions of the Dental Council of New South Wales. The respondent sought to challenge the imposition of conditions on his registration by the Dental Council. These conditions were not based on a finding of incompetence but on a broader assessment of his conduct and professional boundaries. The dispute centred on the legality and fairness of the process leading to the conditions, including questions of bias and the power to compel the production of documents.

The court was required to determine several legal issues. These included whether the process by which the conditions were imposed was fair and in accordance with natural justice, particularly in relation to potential bias. The court also needed to decide whether the respondent was correctly compelled to produce documents and attend proceedings, considering statutory provisions and the common law privilege against self-incrimination. The respondent argued that the Dental Council's dual role as both prosecutor and decision-maker created an apprehension of bias. Furthermore, the respondent claimed that the statutory scheme did not intend to override the common law privilege.

The court found that the apprehension of bias was indeed present due to the conflicting interests of the Dental Council. This was not pre-judgment bias, but rather the apprehension that the Council's mind might be closed due to their dual role. The court applied the "double might" test from Ebner v Official Trustee in Bankruptcy, and found it was satisfied in this case. Regarding the compulsion to produce documents and attend, the court held that the statute did not intend to displace the common law privilege against self-exposure to penalty or forfeiture. Thus, the court found that the proceedings were not lawfully conducted unless the compulsion was exerted.

The final orders of the court upheld the CAT’s decisions, dismissing the respondent’s appeals. The court confirmed that the process leading to the conditions on the respondent's registration was lawful and in accordance with natural justice. The court also found that the compulsion to produce documents and attend was not justified under the statutory scheme.
