Schellenberg v Tunnel Holdings Pty Ltd

In *Schellenberg v Tunnel Holdings Pty Ltd*, the High Court of Australia considered an appeal from the Full Court of the Supreme Court of Western Australia concerning a claim in negligence. The dispute arose from an incident where a hose and coupling separated, causing injury to the appellant. The appellant alleged negligence on the part of the respondent, Tunnel Holdings Pty Ltd, in the assembly, inspection, or maintenance of the compressed air equipment.

The legal issues before the High Court included the circumstances in which the doctrine of *res ipsa loquitur* can be applied, the effect of its application on the burden of proof, and whether it is more than a permissible process of reasoning. The court also considered the principles governing amendments and the reopening of issues at trial, although these were not central to the final determination.

The High Court, in dismissing the appeal, reasoned that the trial judge had erred in applying *res ipsa loquitur* and in drawing inferences of negligence. The Full Court had found that the accident was of a kind that could occur without negligence, particularly in light of expert evidence suggesting a risk of a hose clamped in a normal way coming apart. Furthermore, the Full Court determined that there was insufficient evidence to establish that the respondent had failed to use proper care in the assembly, inspection, or maintenance of the equipment, or that such care would have prevented the separation. The High Court agreed with the Full Court that the trial judge's reliance on the absence of evidence from the respondent regarding assembly, inspection, or maintenance was an impermissible reversal of the onus of proof, as there was nothing requiring the respondent to lead such evidence.

The appeal was dismissed with costs.
