Micallef v ICI Aust Operations & Anor

The applicants, Mr. Micallef and his wife, sought damages for personal injury and loss of consortium respectively, arising from Mr. Micallef's exposure to chemicals manufactured by the first respondent, ICI Australia Operations Pty Ltd, and supplied by the second respondent, Amcor Packaging Australia Pty Ltd. The proceedings were heard in the High Court of Australia.

The central legal issue before the High Court was whether the applicants had established a breach of duty of care by the respondents, and if so, whether that breach caused the injuries and losses claimed. Specifically, the court had to consider the nature and extent of the duty owed by a manufacturer and supplier of chemicals to those who might be exposed to them, and the principles of causation in the context of industrial exposure to potentially harmful substances.

The High Court, in its joint judgment, affirmed the principles of negligence established in *Donoghue v Stevenson* and subsequent authorities. Their Honours found that the respondents owed a duty of care to Mr. Micallef, a duty that extended to taking reasonable steps to prevent foreseeable harm. The court analysed the evidence regarding the nature of the chemicals, the method of their use, and the potential for exposure, concluding that the respondents had failed to discharge their duty of care by not providing adequate warnings or instructions regarding the safe handling and use of the products. The court also addressed the issue of causation, finding that the respondents' breach of duty was a material cause of Mr. Micallef's injuries.

The High Court allowed the appeal, setting aside the judgment of the Full Federal Court and remitting the matter to the Federal Court for determination of the quantum of damages.
