"It is unnecessary, in our view, to determine whether the Regulations so disallowed cease to have effect from the beginning, that is, as if they had never existed, rather than from the point of time when they were disallowed. Assume, however, that they ceased to have effect from the beginning, still the disallowance could not affect transactions that were passed [sic] and closed. (Cf Surtees v Ellison [1829] EngR 594; (1829) 9 B & C 750, 109 ER 278; Barrow v Arnaud [1846] EngR 9; (1846) 8 QB 604; 115 ER 1004.) Here, convictions had taken place, and, if no appeal had been brought, the transaction, undoubtedly, would have been passed [sic] and closed. The question then is whether a right of appeal to this Court, and an appeal brought pursuant to that right, prevent the transaction being treated as passed [sic] and closed. In our opinion they do not, in the present case. 'Appeal' is used in more senses that one: it is a process which may subject (1) the whole matter for rehearing: (2) a question of law only, for review: (3) the facts as well as the law for review, that is, whether the order of the tribunal from which the appeal is brought was right, on the materials which it had before it. Orders nisi to review belong to the third type or description of appeals. Consequently the only question for this Court is whether the convictions or adjudications were, on the materials before the tribunal from which this appeal is brought, in accordance with the law as then existing.
