Mills v Ruthol Pty Ltd

Mills v Ruthol Pty Ltd involved a dispute over the validity of an option to purchase land. The plaintiffs, the Mills, had an option to purchase land from the defendant, Ruthol Pty Ltd. The option was not exercised within the stipulated period due to deception by Ruthol. Upon discovering the deception, the Mills attempted to exercise the option almost two years after the expiration of the option period. Ruthol argued that the option was invalid because it was not exercised in time. The court was required to determine whether the Mills could validly exercise the option outside the stipulated time frame.

The central legal issue was whether the principle that a person cannot take advantage of their own wrongdoing could be invoked to eliminate the time condition for exercising the option. The court found that the deception by Ruthol effectively nullified the time condition, allowing the Mills to exercise the option outside the stipulated period. The equitable principles were also examined, particularly regarding the priority of equitable interests and the nature of a "mere equity". The Mills held an equitable interest in the land, which did not expire at the end of the option period, and this interest prevailed over a subsequent equitable interest taken by another party without notice.

In its reasoning, the court held that the Mills' equitable interest did not cease upon the expiration of the option period. The Mills did not need the assistance of equity to perfect their title, and thus their prior equitable interest remained valid. The court distinguished this situation from the rule in Phillips v Phillips, which applies when a prior equitable interest holder requires equity's assistance to perfect their title, and a third party subsequently acquires an equitable interest without notice. The Mills' equitable interest was not a "mere equity" but a subsisting equitable interest that took priority over the later interest.

The court's final orders recognised the Mills' valid exercise of the option outside the stipulated time frame and upheld their equitable interest in the land. The equitable interest of the Mills prevailed over the subsequent interest of the second option holder.
