28 The difficulty raised by the observations made by the trial judge is that, where a judicial officer makes comments of a personal nature in respect to a party before the court, there may be a very fine line between, first, comments which are material and necessary for the disposition of the case; second, those which it may have been preferable for the judicial officer to avoid using; and third, comments which reasonably show or lead to a reasonable apprehension of bias. This area has been the subject of authoritative consideration both judicially and extrajudicially. In the latter category reference may be made to the paper given by the Chief Justice of Australia at the National Judicial Orientation Program on 16 August 1998 entitled "The Role of the Judge and Becoming a Judge" (published as "Performing the Role of the Judge" (1998) 10 Judicial Officers' Bulletin 57). In the section of the paper dealing with the topic "Fairness", Chief Justice Gleeson dealt with a number of practical aspects of the requirements of fairness which he observed might be easily overlooked. Although his Honour's observations emphasised the risk of persons who are not party to proceedings being unfairly dealt with "by an incautious manner of expressing reasons for judgment" it seems clear that they were not intended to be limited only to third parties. The paper included the following:
The judge only addresses such issues as the parties invite the judge to address, and learns only so much of the facts of the case as will appear from the evidence that is tendered in the course of the proceedings. Fairness, to the parties, and perhaps to third parties, requires that the ultimate judgment be expressed in the light of an understanding of the limitations inherent in the process .
Judges in the course of delivering reasons for judgment, sometimes make findings or comments which reflect a lack of appreciation of those limitations. There may, for example, be a background to litigation, of which the judge will get only a partial glimpse, it may be quite unfair for the judge, in those circumstances, to express unnecessary value judgments, or opinions, or general conclusions of fact, without knowing the whole of the background in question .
...
The absolute privilege which attaches to fair reports of court proceedings should lead judges to be conscious of the harm that may be done, unfairly, to third parties by an incautious manner of expressing reasons for judgment . It is not only fairness to the parties that should be operating as part of a judge's concern . Non-parties can often be seriously damaged by a judge's manner of expressing reasons for judgment. Sometimes this may be the result of mere thoughtlessness. A judge should never cause unnecessary hurt . (emphasis added)
