Bienstein v Bienstein M133/2000

The parties to this proceeding were the applicant, Mr. Bienstein, and the respondent, Mrs. Bienstein. The dispute concerned an application by Mr. Bienstein to set aside a consent order made in the Family Court of Australia on 16 December 1999, which had resolved property settlement proceedings between the parties. The application was heard by Hayne J in chambers.

The central legal issue before the court was whether the consent order of 16 December 1999 should be set aside on the grounds that it was obtained by fraud, duress, or undue influence, or alternatively, on the basis of a material mistake. Mr. Bienstein contended that he had been induced to enter into the consent order by misrepresentations made by Mrs. Bienstein regarding the value of certain assets, and that he had also been under duress at the time of agreeing to the terms.

Hayne J considered the principles governing the setting aside of consent orders in family law proceedings. His Honour noted that such orders, being akin to judgments, are generally final and binding. However, they can be set aside if it can be shown that they were obtained by fraud, duress, or undue influence, or if there was a fundamental mistake. Applying these principles, Hayne J found that the evidence presented by Mr. Bienstein did not establish the necessary elements of fraud, duress, or undue influence. Furthermore, the alleged mistakes were not of a fundamental nature that would warrant setting aside the consent order.

Consequently, Hayne J dismissed the application to set aside the consent order.
