Cattanach v Melchior

This case concerned an appeal to the High Court of Australia by Dr Cattanach and the State of Queensland against a judgment of the Queensland Court of Appeal. The respondents, Mr and Mrs Melchior, had sued Dr Cattanach, a specialist obstetrician and gynaecologist, and the State (as the successor to the relevant health authority) for damages arising from the birth of their third child. Dr Cattanach had performed a sterilisation procedure on Mrs Melchior in 1992, but she subsequently gave birth to a healthy child in 1997. The Melchiors claimed damages for the costs associated with raising and maintaining this child until the age of 18.

The central legal issues before the High Court were whether damages were recoverable for the past and future costs of raising and maintaining an unintentionally born child, and whether any such award should be reduced by reference to the benefits and pleasures derived from the child. The court was required to consider whether the birth of a child, in these circumstances, constituted a legal harm for which damages could be recovered, and whether ordinary tortious rules regarding causation and economic loss applied, or if a departure was necessary due to public policy considerations surrounding family relationships.

A majority of the High Court, by dismissing the appeal, upheld the decision of the Queensland Court of Appeal. The reasoning focused on the established principles of negligence and damages. The court acknowledged that while the birth of an unintended child results in financial costs, it also brings benefits and pleasures, making a purely financial assessment of harm problematic and potentially indeterminate. However, the majority concluded that the law of negligence, as it stood, permitted recovery for the financial costs of raising an unintentionally born child, even in the absence of physical injury to the parents. The court rejected arguments that such claims should be limited to cases involving disability or that the benefits of parenthood should automatically offset the costs. The court found that the claim, as presented, was not an unrecoverable instance of pure economic loss, but rather a claim for consequential economic loss flowing from a negligent act that resulted in an unintended birth.

The appeal was dismissed with costs.
