The distinction between an appeal in the strict sense and an appeal by way of rehearing is explained in the judgment of Dixon J. in Victorian Stevedoring and General Contracting Co. Pty. Ltd. and Meakes v. Dignan [1] . Appeals to this Court under s. 73 of the Constitution are sometimes described as appeals by way of rehearing, because on such appeals questions of fact, as well as questions of law, are open. But such appeals are really appeals in the strict sense: they must be decided on the materials which were before the court from which the appeal comes, and no fresh evidence can be admitted. On the other hand, the so-called appeal from a board of review to this Court is clearly an appeal by way of rehearing. The jurisdiction exercised is in truth original jurisdiction, and not appellate jurisdiction. The general position with regard to such "appeals" may be fully explained by quoting passages from two judgments. In Federal Commissioner of Taxation v. Lewis Berger & Sons (Australia) Ltd. [1] , Starke J. said: "The appeal may be brought from any decision of the Board which, in the opinion of this Court, involves a question of law. The Board, in its proceedings, did not exercise the judicial power of the Commonwealth, but an administrative function, namely, that of reviewing the Commissioner's assessments for the purpose of ascertaining the taxable income upon which tax should be levied. The appeal to this court submits the ascertainment of the taxpayer's liability to judicial review and ascertainment, but the so-called appeal is a proceeding in the original, and not within the appellate, jurisdiction of the Court. It follows, I think, that the parties on this appeal are not limited to the material that was before the Board of Review, but are entitled to adduce before this Court such evidence in support of, or in answer to, the appeal as is relevant to the matter. The material before the Board and its decision and reasons should be brought before this Court, and the parties may use this material if they so desire, but further or additional evidence may be adduced, or the appeal may be conducted as an original cause brought in this Court." [2] In Federal Commissioner of Taxation v. Sagar [3] , Williams J. said: "It is only competent for the Court to entertain an appeal under s. 25 (7) if the decision of the Board involves a question of law. Unless the statute provides that some portion of the Board's decision is to be unappealable, the whole decision and not merely the question of law is then open to review and the Court must rehear the whole case although it rejects the point of law The appeal is a proceeding in the original jurisdiction of the Court so that, unless the parties agree that the evidence given before the Board shall be used on the appeal, the evidence must be tendered again, and, as the appeal is a rehearing, further evidence can be called."
