Yisrael v Chamberlain John Deer Pty Limited

This matter came before the High Court of Australia on an application for special leave to appeal by the applicant, Yisrael, against the respondent, Chamberlain John Deer Pty Limited. The dispute concerned the assessment of damages following an accident. The applicant sought to challenge the decision of the lower courts on several grounds, including the application of the principle in *Leisbosch Dredger in Ownership v Ediston Shipping Co Ltd* to disentitle the plaintiff to damages for a lost opportunity to purchase a house at a favourable interest rate, the calculation of interest on past economic loss by allowing a credit for sickness and invalid benefits, and the exclusion of certain hospital and medical expenses.

The primary legal issues before the High Court were whether the principle established in *Leisbosch* retained any operation in tort actions where a plaintiff's loss stemmed from their impecuniosity following an accident, and if so, how that operation should be defined. Additionally, the court was asked to consider whether the trial judge's calculation of interest on past economic loss, by crediting the defendant with payments received by the plaintiff from social security benefits, represented an appropriate development of the principles concerning credits for workers' compensation payments as discussed in *Batchelor v Burke*. The court also considered whether the Court of Appeal had erred in assuming that certain hospital and medical expenses had been allowed within the general damages figure when there was no express inclusion and evidence to the contrary.

In relation to the *Leisbosch* principle, the applicant argued that the trial judge had incorrectly applied it to deny damages for the lost opportunity to purchase a home at a particularly advantageous interest rate. The facts indicated that prior to the accident, the plaintiff had applied for and been accepted into a subsidized first home buyers scheme. Following the accident, he was unable to proceed with the purchase due to his financial circumstances. The applicant contended that the principle in *Leisbosch*, which generally disentitles a plaintiff to recover damages caused by their own impecuniosity, should not apply in this context, particularly where the impecuniosity arose directly from the tortious act. The court was also asked to review the approach to calculating interest on past economic loss, with the applicant arguing that the credit for sickness and invalid benefits was an overreach beyond established authority. The applicant further submitted that the Court of Appeal's assumption regarding the inclusion of medical expenses in general damages was unwarranted.
