While the High Court of Australia unanimously agreed that relief should be granted in favour of Mrs Nelson, the judges differed in their approach in ascertaining the appropriate relief that should be granted. What is significant for present purposes is the decision of the majority, comprising Deane, McHugh, and Gummow JJ, which departed from the traditional all-or-nothing approach of the illegality defence that would have resulted in the claimants either succeeding in their claim, or failing entirely. Instead, the majority held that the question of illegality was bound up with the underlying policy of the DSHA, which was to provide public moneys to facilitate the purchase of housing by eligible persons, but on the footing that the eligible person was not to own another dwelling. The purpose of the DSHA was sufficiently served by the penalties it provided. As such, the denial of a resulting trust would cause prejudice to Mrs Nelson without furthering the objects of the DSHA (at 158, per Deane and Gummow JJ; at 195, per McHugh J). However, as the price of obtaining the relief she sought, for the recognition and enforcement of a resulting trust in respect of the whole of the balance of the proceeds of sale of the first house, Mrs Nelson had to take steps to satisfy the demands of the underlying policy of the DSHA. This required her to pay to the Commonwealth the benefit in respect of the purchase of the second house which she had obtained by her unlawful conduct (at 159, per Deane and Gummow JJ; at 195, per McHugh J). Accordingly, Nelson represented a departure from the formal reliance principle in Tinsley towards an approach which gives a court the discretion to calibrate the appropriate relief to be granted instead (see further, Man Yip, “The Restitutionary Aftermath of Contractual Illegality” [2015] RLR 106).
