"It is that the Court of Appeal should not interfere with the discretion of a judge acting within his jurisdiction, unless the Court is clearly satisfied that he was wrong. But the Court is not entitled simply to say that, if a judge had jurisdiction, and had all the facts before him, the Court of Appeal cannot review his order, unless he is shown to have applied a wrong principle. The Court must if necessary, examine anew the relevant facts and circumstances, in order to exercise by way of review a decision which may reverse or vary the Order. Otherwise, in interlocutory matters, the judge might be regarded as independent of supervision. Yet an interlocutory Order of the judge may often be of decisive importance on the final issue of the case, and may be one which requires careful examination by the Court of Appeal."
