29While we understand that the appellant is dissatisfied with the decision of the Tribunal, for the reasons set out below, we are not persuaded by her arguments that the Tribunal's reasons for decision evidence 'bias' by the Judicial Member in making the findings he made.
30As noted by the respondent, it is well established that 'bias' is a breach of the obligation to accord procedural fairness, sometimes called the 'rules of natural justice'. In this regard, subs. 73(2) of the ADT Act provides that while the Tribunal is not bound by the rules of evidence it is 'subject to the rules of natural justice'.
31There are two aspects to bias, actual bias and apprehended bias. As actual bias by the Judicial Member has not been raised by the appellant we have not considered this any further. However, for completeness, we find that there is no evidence on which such an argument could be made.
32The apprehension of bias principle and its application were discussed by the High Court in Ebener v Official Trustee in Bankruptcy [2000] HCA 63; (2000) 205 CLR 337, at [3] to [8], per Gleeson CJ, McHugh, Gummow and Hayne JJ, as follows:
3. Fundamental to the common law system of adversarial trial is that it is conducted by an independent and impartial tribunal. .... It is unnecessary, however, to explore the historical origins of the principle. It is fundamental to the Australian judicial system.
4. The principle has been applied not only to the judicial system but also, by extension, to many other kinds of decision making and decision maker. ...
5. ...
6. Where, in the absence of any suggestion of actual bias, a question arises as to the independence or impartiality of a judge (or other judicial officer or juror), as here, the governing principle is that, ..., a judge is disqualified if a fair-minded lay observer might reasonably apprehend that the judge might not bring an impartial mind to the resolution of the question the judge is required to decide [citations omitted]. That principle gives effect to the requirement that justice should both be done and be seen to be done [citations omitted], a requirement which reflects the fundamental importance of the principle that the tribunal be independent and impartial. It is convenient to refer to it as the apprehension of bias principle.
7. The apprehension of bias principle may be thought to find its justification in the importance of the basic principle, that the tribunal be independent and impartial. So important is the principle that even the appearance of departure from it is prohibited lest the integrity of the judicial system be undermined. There are, however, some other aspects of the apprehension of bias principle which should be recognised. Deciding whether a judicial officer (or juror) might not bring an impartial mind to the resolution of a question that has not been determined requires no prediction about how the judge or juror will in fact approach the matter. The question is one of possibility (real and not remote), not probability. Similarly, if the matter has already been decided, the test is one which requires no conclusion about what factors actually influenced the outcome. No attempt need be made to inquire into the actual thought processes of the judge or juror.
8. The apprehension of bias principle admits of the possibility of human frailty. Its application is as diverse as human frailty. Its application requires two steps. First, it requires the identification of what it is said might lead a judge (or juror) to decide a case other than on its legal and factual merits. The second step is no less important. There must be an articulation of the logical connection between the matter and the feared deviation from the course of deciding the case on its merits. The bare assertion that a judge (or juror) has an "interest" in litigation, or an interest in a party to it, will be of no assistance until the nature of the interest, and the asserted connection with the possibility of departure from impartial decision making, is articulated. Only then can the reasonableness of the asserted apprehension of bias be assessed.
33In a more recent case, Michael Wilson & Partners Ltd v Nicholls [2011] HCA 48, the High Court (per Gummow ACJ, Hayne, Crennan and Bell JJ) said the following:
31. It has been established by a series of decisions of this Court [citation omitted] that the test to be applied in Australia in determining whether a judge is disqualified by reason of the appearance of bias (in this case, in the form of prejudgment) is whether a fair-minded lay observer might reasonably apprehend that the judge might not bring an impartial and unprejudiced mind to the resolution of the question the judge is required to decide. No party to the present appeal sought in this Court, or in the courts below, to challenge that this was the test to be applied.
32. As the plurality in Johnson v Johnson [citation omitted] explained, "[t]he hypothetical reasonable observer of the judge's conduct is postulated in order to emphasise that the test is objective, is founded in the need for public confidence in the judiciary, and is not based purely upon the assessment by some judges of the capacity or performance of their colleagues."
33. Because the test is objective it is important to keep an inquiry about apprehension of bias distinct from any inquiry about actual bias. An inquiry about actual bias in the form of prejudgment would require assessment of the state of mind of the judge in question. No doubt that would have to be done, at least for the most part, on the basis of what the judge had said and done. But to allow an inquiry about whether the judge had in fact prejudged some issue to enter into a debate about what a fair-minded lay observer might apprehend is to introduce considerations that are irrelevant to the issue that is to be decided when a party submits that there is or was a reasonable apprehension of bias. ...
34In our view, when objectively assessed, the Judicial Member made his findings as to whether the disclosure of the information in issue could reasonably be expected to expose persons to a risk of serious harassment or intimidation, on the basis of all the material before him, including the affidavit evidence of the respondent's solicitor, Ms Anderson, and that of the appellant.
35We note that the affidavit of Ms Anderson was filed and served subsequent to the 31 October 2012 planning meeting (i.e. on or about 7 December 2012) and the appellant filed and served her affidavit almost two months after that (i.e. on 28 February 2013). We also note that in December 2012, the respondent provided to the Tribunal, in confidence (see s 107 of the GIPA Act), statements made by some of the employees who had been interviewed during the course of the investigation (see at [29] of the Tribunal's Decision, where the Judicial Member sets out the information before him). These statements were made for the purpose of the appellant's GIPA application and the appellant was given a redacted copy of these statements. The redactions were the names of the employees who made the statement and any information that may identify that person. However, the copy of the statement released to the appellant included the person's reasons for objecting to the disclosure of the information that the person had given to the investigator. We note these reasons included concerns about being bullied or intimidated by the appellant if the information they provided to the investigator were to be released to the appellant.
36In our view, the remarks of the Judicial Member, at [60], about concerns expressed by the employees is a reference to the concerns as expressed in these employee statements prepared for the purpose of the GIPA Act and not a reference to what was asserted against the appellant in the course of the investigation.
37In her affidavit, the appellant addressed these concerns, as well as those raised by Ms Anderson in her affidavit.
38Accordingly, we do not accept the appellant's contention that the Judicial Member took as fact the statements contained in the information at issue.
39Nor do we accept that the Judicial Member's disclosure of the name of one of the employees, who was interviewed by the investigator, evidences a lack of impartiality by the Judicial Member in determining the appellant's application for review. While disclosure of this nature should be avoided (see s 107 of the GIPA Act), in this instance, the disclosure was clearly inadvertent. It was made at a planning meeting where the only persons in attendance were the appellant and the solicitor for the respondent and no information, other than the name of the particular employee was disclosed. At no time following the disclosure, did the appellant ask the Judicial Member to recuse himself. On the contrary, she complied with the orders that were made on this day and those that were made at the subsequent planning meeting in April 2013.
40Accordingly, in accordance with the two step test as described in Ebener (supra), at [8], we do not accept the appellant's contention that the Judicial Member's inadvertent disclosure was such that a fair-minded lay observer might reasonably apprehended that the Judicial Member did not bring an impartial and unprejudiced mind to the determination of the appellant's review application. The Judicial Member's observation of the appellant when he made the inadvertent disclosure, was clearly a matter relevant to the issue as to whether the respondent had established that a disclosure of the information in issue 'could reasonably be expected to' expose a person to a risk of harm or of serious harassment or serious intimidation. It was not the only matter before the Judicial Member in regard to this issue, but it was a matter raised by the respondent in Ms Anderson's affidavit and responded to by the appellant in her affidavit in reply. In reaching his conclusions, the Judicial Member was clearly entitled to have regard to all the information before him, including his own observations of the appellant at the 31 October planning meeting.
41We note that at no time following his inadvertent disclosure and prior to the publication of the Tribunal's Decision, did the appellant object to the Judicial Member determining her application. She had ample opportunity to do so, if this was of concern to her following the 31 October 2012 planning meeting. We can only assume it was of no concern to her.
