Resolving the Central Issue
55 I start with the procedure contemplated by the Defendants - and by my original orders in relation to the Receiver's files. Messrs Curran and Burke would be asked to give evidence, if necessary by subpoena, as to why they did not proceed with an offer. Then any submissions would be heard from the Plaintiffs and the Defendants. The Referee, like the jury in Webb v the Queen, would be warned that he must retain an open mind to any such new evidence. The question is whether a fair-minded and informed observer would nonetheless entertain a reasonable apprehension of a lack of impartiality on the part of the Referee, by reason of pre-judgment, notwithstanding that the procedures contemplate the taking of further evidence, the opportunity for further submissions and in a context where the Referee would be under no misapprehension as to his duty of impartiality. It is significant that the High Court in Webb by majority concluded, in the case of a juror who gave a bunch of flowers to the deceased's mother via a court officer during the trial, that in the circumstances a fair-minded observer would not have had an apprehension of lack of impartiality on the part of the juror. This conclusion emphasised that the judge had impressed on the jury the need to have regard only to the evidence, which they were to consider in a dispassionate manner putting aside all feelings of sympathy and emotion. It can be taken that a similar stricture is made by this Court to the Referee; to put aside any earlier conclusion and take into account any new facts emerging from that procedure as well as the submissions of the parties.
56 Furthermore the Referee is not operating in a strict Livesey situation in that, while the task before him is the determination of the same matter of fact - the valuation of the units - ex hypothesi he will have additional facts before him. No-one suggests that a trial judge cannot deal with a case remitted back by an appeal court taking into account the appeal court's directions, by reason of pre-judgment. The Referee's position is no different. The Referee, if he changes his mind, is not necessarily admitting error but accommodating further evidence and submissions.
57 While a referee is not to be treated as in the same position as a juror, nonetheless the supervisory role of the court in relation to the performance by a referee of his or her quasi-judicial function is such that it could be expected that such a stricture would be taken seriously.
58 The Plaintiffs' case amounts to this. The Referee both in consulting the Receiver's files and now in the two further conversations when in the process of confirming his conclusions, the Referee denied procedural fairness to the Plaintiffs. That coupled with the prior determination of the factual issue of what the units were worth suffices to give rise to a reasonable apprehension of bias, based on pre-judgment.
59 It cannot be the case that every denial of procedural fairness gives rise to a reasonable apprehension of bias though in a more serious case it may well do so, by bespeaking a closed mind or prejudice. To suppose otherwise would contradict the assumption underlying the well established Hardiman principle. That assumption is that a referee, like a tribunal, should not take any active role in proceedings which may bear upon a failure to provide procedural fairness. This is because the matter may return to the Tribunal after an adverse finding on procedural fairness for a re-hearing and the assumption is that the Tribunal can still hear the matter. Obviously in some cases the circumstances of unfairness may be so serious that another body should deal with it, but by no means is this inevitably so.
60 The question is therefore whether the circumstances that gave rise to the procedural unfairness are such as to rise to the level where a reasonable and informed observer has a "reasonable apprehension" of bias. First, I am satisfied that there is not sufficient in the two stage production of documents from the Receiver's files to justify a reasonable apprehension of bias. In particular, I do not consider the two conversations tip the balance; that is to say, taking all the circumstances in their context and considering their cumulative effect on a fair-minded observer, I do not consider there would be an apprehension of bias. The volunteering of the details of the two conversations reinforces rather an impression of candour. It is true, as I have said, the evidence of the two oral conversations bears upon the potential availability of higher offers, if for example more time had been allowed. But that matter can readily be tested against what Messrs Burke and Curran now say would have influenced them in deciding to proceed or not with an offer and against other relevant facts.
61 The second issue is whether the Referee's prior finding in those circumstances, coupled as it was by procedural unfairness though unwitting, would lead a fair-minded observer to conclude that the Referee was parti pris, and thus might not bring a genuinely impartial mind to bear on any new evidence or submissions so generated, however hard he tried. While we all know that psychologically, admitting error is not easy, here the Referee is simply required to take account of new evidence and further submissions. If it be the case that, with all the other circumstances, a different conclusion by the Referee were warranted, there can be no embarrassment such as to disincline the Referee from that course. That is reinforced by the strictures expressed in this judgment of the importance of giving fair and proper weight to all relevant facts and submissions, retaining an open mind free of prejudgment. In saying that, I do not of course express any view one way or the other on the subject matter of the Referee's determination or whether the further facts and submissions will require a different conclusion to the Referee's previous one. The Referee must simply do his job in an impartial, open-minded way.
