Soon after the Judicature Act came into operation a full exposition of the duty of a court of appeal in rehearing questions of fact was made by Baggallay J.A. The case was The Glannibanta [3] , and the Court consisted of James L.J., Baggallay J.A., and Lush J. After referring to the language of the Privy Council in admiralty cases to the effect that, if there was conflicting evidence and the judge, having had the opportunity of seeing the witnesses and observing their demeanour, had come on the balance of testimony to a clear and decisive conclusion, the Privy Council would not be disposed to reverse such a decision except in cases of extreme and over-whelming pressure, his Lordship said that they felt just as strongly the great weight that is due to the decision of a judge of first instance whenever in a conflict of testimony the demeanour and manner of the witnesses who have been seen and heard by him are material elements in the consideration of the truthfulness of their statements; but - (1) the parties are entitled to demand the decision of the court of appeal on questions of fact as well as of law; (2) the court cannot excuse itself from weighing conflicting evidence and drawing its own inferences and conclusions, though it should bear in mind that it has neither seen nor heard the witnesses and should make due allowance in that respect; (3) in the case in hand there was no reason to suppose that the judge at all proceeded upon the manner or demeanour of the witnesses. The decision below was reversed. In the same year in Bigsby v. Dickinson [1] , James L.J., Baggallay and Bramwell JJ.A. followed The Glannibanta [2] and reversed a Vice-Chancellor's decision on facts in a case of nuisance. Their Lordships emphasized that an appeal on questions of fact existed. Then came the often cited case of Coghlan v. Cumberland [3] . Lindley M.R. sitting with Rigby and Collins L.JJ. said in substance that the court of appeal must (1) rehear and reconsider the materials, (2) make up its own mind taking the judgment of the primary judge into account, (3) be guided by his impression when the question which witness is to be believed turns on demeanour, (4) be warranted in differing even on credibility when other circumstances show whether the evidence is credible or not. It will be seen that so far the tendency of the decisions was to formulate and concede the restrictive considerations or rules but, at the same time, to emphasize and act on the power to review findings of fact. This tendency may be seen in Montgomerie & Co. Ltd. v. Wallace-James [4] . The House of Lords reversed concurrent findings of fact that there had been a user of a way by the public of forty years duration. Lord Halsbury L.C. proceeded on the ground that there was no question of truthfulness of testimony but the question was what were the proper inferences [5] . Lord Shand conceded the importance to be attached to the primary judge's opportunity of seeing the witnesses and to the fact of the finding being unanimously sustained, but said that the case was a special one [6] . Lord Davey dealt with both topics extensively in reasons which should be read though this is not the place to set them out [7] . Lord Lindley said that there was no rule preventing the reversal of concurrent findings [8] . The earliest occasion on which this Court dealt with the matter was probably in Dearman v. Dearman [9] . The Court restored the decision of a primary judge who refused to act on the evidence of persons who said they were eyewitnesses of adultery. The position of a court of appeal was examined at length by Isaacs J. [1] . Four years later in Khoo Sit Hoh v. Lim Thean Tong [2] Lord Robson for the Judicial Committee restated the considerations. The substance of what his Lordship said was that (1) the court of appeal should be influenced by the opinion of the primary judge because he can estimate the intelligence position and character of the witnesses; (2) it should remember that many points are elucidated at the trial which may be represented ambiguously or imperfectly by the notes and the elucidation may be through counsel; (3) but it may turn out (a) that the judge has failed to take something into account, or (b) that he has given credence to evidence afterwards shown to be self-inconsistent or contrary to indisputable fact; (4) except in rare cases such as those which are capable of being dealt with wholly by argument a court of appeal will hesitate to interfere. In the same year in this Court in Craine v. Australian Deposit & Mortgage Bank Ltd. [1] , Griffith C.J. and Isaacs J. reversed a finding by Madden C.J. as to the date when a fence was erected, basing themselves on the authority of Lord Robson [2] . Barton J. dissented, placing his dissent on the authority of Isaacs J. in Dearman v. Dearman [3] . An interesting contribution to the topic was made in MacBean v. Trustees Executors & Agency Co. Ltd. [4] by Cussen J., who (a) commented on the judicial tendency to distinguish between the findings of judges and those of juries (b) pointed out that in order LVIII, r. 1, of the then Rules of the Supreme Court of Victoria the words "by way of rehearing" were not reproduced and that the two classes of findings were assimilated, and (c) deprecated the court of appeal acting upon its own opinion upon a question of quantum. Next an example occurred of the connection which may exist between logical inference from observed facts and the impression created by witnesses. In Perpetual Executors & Trustees Association of Australia Ltd. v. Wright [5] , this Court refused to disturb a finding that a document of an unusual nature was genuine because, although made on a comparison of handwriting, the demeanour and credibility of a witness who said that he had found the document must have entered into the question. The principles in question and the differences that exist between primary and appellate courts were discussed again by Barton A.C.J. [6] , by Isaacs, Gavan Duffy and Rich JJ. [7] . Shortly afterwards in Scott v. Pauly [8] , where a decision of the Supreme Court upsetting the finding of the primary judge (Northmore J.) was affirmed, Isaacs J. took occasion to discuss the authorities and their effect [9] . Then once more the distinction was emphasised by the Judicial Committee between cases where the result depends upon a view taken of conflicting testimony and cases where it depends upon inferences from uncontroverted facts: Dominion Trust Co. v. New York Life Insurance Co. [1] . In Mersey Docks & Harbour Board v. Procter [2] , Viscount Cave referred again to the subject and said that it was the duty of a court of appeal to make up its own mind, not disregarding the judgment appealed from and giving special weight to that judgment in cases where the credibility of witnesses comes in question but with full liberty to draw its own inferences from the facts proved or admitted. The distinction between inferences from fixed facts and findings based on testimony frequently recurs. In Cooper v. General Accident, Fire, & Life Assurance Corporation Ltd. [3] Lord Cave said: "The question is, not what are the facts, but what is the proper inference to be drawn from the facts proved, and upon that point, as has been often said, the appellate tribunal is not less competent to judge than the judge who actually hears the case" [4] . In S.S. Hontestroom v. S.S. Sagaporack [5] Lord Sumner gave an important summary of the competing considerations. His Lordship said: "Of course, there is jurisdiction to retry the case on the shorthand note None the less, not to have seen the witnesses puts appellate judges in a permanent position of disadvantage as against the trial judge, and, unless it can be shown that he has failed to use or has palpably misused his advantage, the higher Court ought not to take the responsibility of reversing conclusions so arrived at, merely on the result of their own comparisons and criticisms of the witnesses and of their own view of the probabilities of the case. The course of the trial and the whole substance of the judgment must be looked at, and the matter does not depend on the question whether a witness has been cross-examined to credit or has been pronounced by the judge in terms to be unworthy of it. If his estimate of the man forms any substantial part of his reasons for his judgment the trial judge's conclusions of fact should, as I understand the decisions, be let alone" [6] . These cautions did not prevent this Court reversing Mann J. on a pure question of fact depending on testimony in Federal Commissioner of Taxation v. Clarke [7] . Discussions of the principles will be found per Isaacs A.C.J. [8] and by Rich J. dissenting [1] . In the same way in Webb v. Bloch [2] , Knox C.J. [3] and Isaacs J. [4] reversed a finding of Starke J. that there was an absence of malice in the publication of a libel by various persons called as witnesses before him. They did so on the ground that his finding was not based on credibility. Isaacs J. referred to the existence of "a constitutional and statutory duty upon this appellate Court to form its own independent opinion as to the proper construction of documents and the proper inferences from the evidentiary facts" [5] . Some of these actual decisions may seem to impair the value in practice of the rules which govern the duty of the court of appeal in dealing with questions of fact, but from the very nature of such questions it is impossible for a report to reproduce the evidence which influenced the court except in outline and in many of the cases the strength of the considerations against the findings of the primary judges was very great. Any tendency to relax the rules was checked by the House of Lords in Powell v. Streatham Manor Nursing Home [6] . Lord Wright made the following points: 1. An appellant's counsel opens as he chooses. (It is to be hoped that in making this point his Lordship did more than justice to counsel and less than justice to appellate courts.) 2. There is an antinomy in a duty to rehear and a restriction to recorded material. 3. Before a court of appeal upsets a finding into which credibility enters it should be convinced that the primary judge is wrong. 4. The court of appeal is not entitled to ignore findings based on credibility and to consider probabilities on the written material. 5. His Lordship repeats the questions put by Lord Sumner in S.S. Hontestroom v. S.S. Sagaporack [7] . Finally Lord Wright discusses the modes of assessing the value of oral testimony. Another kind of finding was brought more decisively under the protection of the rules in Owen v. Sykes [8] , where the court of appeal refused to review an award by Greaves-Lord J. of £10,000 for personal injuries and discussed the grounds on which an appellate court should interfere with an estimate of damages by a trial judge. In Yuill v. Yuill [9] , Lord Greene M.R. restates the standards and refers to Hvalfangerselskapet Polaris A/S. v. Unilever Ltd. [1] as an illustration of the jurisdiction of the court of appeal to set aside a finding based in part on credibility because on carefully checking the whole evidence by a critical examination the primary judge's impression on the subject of demeanour was found to be mistaken. In Watt or Thomas v. Thomas [1] , Lord Thankerton described the principle as a simple one and stated it thus: "I. Where a question of fact has been tried by a judge without a jury, and there is no question of misdirection of himself by the judge, an appellate court which is disposed to come to a different conclusion on the printed evidence, should not do so unless it is satisfied that any advantage enjoyed by the trial judge by reason of having seen and heard the witnesses, could not be sufficient to explain or justify the trial judge's conclusion; II. The appellate court may take the view that, without having seen or heard the witnesses, it is not in a position to come to any satisfactory conclusion on the printed evidence; III. The appellate court, either because the reasons given by the trial judge are not satisfactory, or because it unmistakably so appears from the evidence, may be satisfied that he has not taken proper advantage of his having seen and heard the witnesses, and the matter will then become at large for the appellate court. It is obvious that the value and importance of having seen and heard the witnesses will vary according to the class of case, and, it may be, the individual case in question. It will hardly be disputed that consistorial cases form a class in which it is generally most important to see and hear the witnesses, and particularly the spouses themselves" [2] . Lord Simonds said: "I suppose that if ever there was a class of case, in which an overwhelming advantage lies with the judge who has the witnesses before him, it is in the arena of connubial infelicity and discord" [3] .
