Hill v Ziymack

This case involved an appeal to the High Court of Australia from a decision of the Supreme Court of New South Wales in Equity. The dispute arose between Barbara Ziymack, the respondent, and the widow and administratrix of the estate of W. C. Hill, the appellant. Following a successful action for conversion brought by the appellant against the respondent, in which the respondent was ordered to pay damages, the respondent instituted proceedings in equity seeking to set off certain claims against the verdict and to restrain execution on the judgment.

The primary legal issues before the High Court were whether the respondent was entitled to an equitable set-off against the damages awarded in the tort action, whether moneys voluntarily expended by the respondent in paying off a mortgage on the subject matter of the conversion action could be recovered from the estate, and whether moneys advanced for the benefit of the intestate estate before the grant of administration could be recovered without ratification by the administrator. The court also considered whether a person who voluntarily pays off a mortgage over another's personal property under a mistake of fact has a lien on that property.

The High Court determined that equity would not restrain a plaintiff from issuing execution on a damages verdict on the ground of equitable set-off merely because of unsettled accounts between the parties, even if those accounts related to the property in question, citing *Rawson v. Samuel*. The court held that in an action for conversion, the defendant is entitled to have moneys expended in paying off a mortgage on the subject matter taken into account in reduction of damages, as per *Peruvian Guano Co. v. Dreyfus Bros. and Co.*. Furthermore, moneys advanced for an intestate estate before administration, even at the request of the future administrator, cannot be recovered from the estate unless ratified by the administrator after appointment, following *In re Watson; Ex parte Phillips*. The court also found that a person voluntarily paying off a mortgage over another's property under a mistake of fact, not caused or contributed to by the mortgagor, has no lien on the property, referencing *Falcke v. Scottish Imperial Insurance Co.*.

The High Court reversed the decision of the Supreme Court of New South Wales. It found that the respondent had no right to an equitable set-off, that her claims for moneys paid to discharge debts and for moneys lent were essentially legal claims that could not be enforced in equity in this manner, and that there was no basis for a lien on the funds in court. Consequently, the court held that the respondent was not entitled to the relief granted by the Supreme Court.
