Briginshaw v Briginshaw

The case of Briginshaw and Another v. Briginshaw concerned a petition for dissolution of marriage brought by the husband, Frederick Joseph Briginshaw, against his wife, Clarice Briginshaw, on the grounds of her adultery with a co-respondent, Crawford. The matter came before the Supreme Court of Victoria, and the husband appealed to the High Court of Australia.

The central legal issue before the High Court was the appropriate standard of proof required to establish adultery in divorce proceedings under the Marriage Act 1928 (Vict.). Specifically, the court had to determine whether the standard was proof beyond reasonable doubt, as in criminal proceedings, or a different standard applicable to civil matters.

The High Court, in its judgment, affirmed the decision of the Supreme Court of Victoria. The Court reasoned that the Marriage Act 1928, particularly sections 80 and 86, required the court to "satisfy itself, so far as it reasonably can, as to the facts alleged" and to pronounce a decree nisi if "satisfied that the case of the petitioner is established." The Court held that these provisions did not mandate proof beyond reasonable doubt. Instead, the ordinary civil standard of proof, based on a preponderance of probability, was to be applied, albeit with the caution appropriate to a serious allegation such as adultery. The Court found that the trial judge had erred by applying a standard of proof akin to the criminal standard, and therefore, the case was remitted for a new trial.
