Brown v Brown

In *Brown v Brown*, the Supreme Court of New South Wales considered an application for a writ of prohibition. The applicant, Mrs Brown, sought to prevent the enforcement of an order made by a magistrate for the maintenance of a child. This order was made subsequent to a decree of judicial separation granted to Mrs Brown against her husband, Mr Brown, under the *Matrimonial Causes Act (N.S.W.)*. The original decree of judicial separation did not include any provisions for the maintenance of the child.

The central legal issues before the Court were whether the magistrate had jurisdiction to make the maintenance order under the *Deserted Wives and Children Act (N.S.W.)*, and whether the prior decree of judicial separation operated as *res judicata* to preclude the subsequent maintenance proceedings. Additionally, the Court had to consider the admissibility and sufficiency of evidence presented to prove the prior judicial proceedings, specifically concerning the requirements for a certified copy of proceedings under the *Evidence Act (N.S.W.)*.

The Court reasoned that the *Deserted Wives and Children Act (N.S.W.)* conferred jurisdiction on magistrates to make maintenance orders even in the absence of a prior order for maintenance in a judicial separation decree. It was held that the doctrine of *res judicata* did not apply because the subject matter of the two proceedings was different; the judicial separation decree dealt with the marital status and separation, while the maintenance proceedings concerned the statutory obligation to support a child. The Court also found that the evidence presented, a certified copy of the judicial separation proceedings, met the requirements of the *Evidence Act (N.S.W.)* and the *Interpretation Act (N.S.W.)*, establishing the prior proceedings.

The application for a writ of prohibition was dismissed.
