Ryan v Ryan

This case concerned an appeal to the High Court of Australia from a decision of the Full Court of Western Australia. The parties were Thomas Ryan (husband) and Henrietta Ryan (wife). The wife had petitioned for judicial separation on the grounds of adultery, alleging she discovered her husband and another woman in the act of adultery. The trial judge had dismissed the petition, finding the adultery not proven. The wife appealed to the Full Court, which allowed the appeal and granted a decree of judicial separation. The husband then appealed this decision to the High Court.

The legal issues before the High Court were whether the Full Court erred in reversing the trial judge's finding of fact and, alternatively, whether a new trial should be granted on the basis of fresh evidence discovered since the original hearing. The husband argued that the Full Court's finding of adultery was not supported by the evidence, particularly concerning the presumption of adultery in circumstances where the parties were disturbed shortly after reaching a secluded location. The wife contended that the trial judge had not adequately considered the antecedent facts and circumstances, and alternatively, that fresh evidence warranted a new trial.

The High Court, in exercising its appellate jurisdiction, considered the provisions of the *Appellate Jurisdiction Act 1911* (W.A.) and the *Judiciary Act 1903* (Cth). While acknowledging the general reluctance to grant new trials based on deficiencies in proof, the Court found that the specific statutory provisions allowed for a broader exercise of discretion in matrimonial causes. The Court determined that granting a new trial, in light of the discovered fresh evidence, would conduce to the ends of justice. This evidence included a sworn statement made by a key witness shortly after the alleged events, which the Court considered less susceptible to the dangers of belatedly supplied evidence.

Consequently, the High Court set aside the order of the trial judge and the order of the Full Court, except in so far as the latter related to costs. The Court ordered that a new trial be had.
