Marsden v Unimin Australia Ltd; Price v Resolute Resources

The High Court of Australia considered appeals from decisions of the Supreme Court of New South Wales in two related matters, *Marsden v Unimin Australia Ltd* and *Price v Resolute Resources*. Both cases concerned claims for damages for personal injury arising from the alleged negligence of the respective respondents, Unimin Australia Ltd and Resolute Resources, in relation to the operation of mining equipment. The appellants, Mr Marsden and Mr Price, were employees or former employees of the respondents and alleged that they had suffered injuries as a result of the respondents' failure to take reasonable care for their safety.

The central legal issue before the High Court was whether the respondents had breached their duty of care to the appellants by failing to implement adequate safety measures to prevent the development of vibration-induced injuries, specifically Hand-Arm Vibration Syndrome (HAVS). The appellants contended that the respondents ought to have known of the risks associated with prolonged exposure to vibration from the mining equipment and should have taken steps to mitigate those risks, such as limiting exposure times or providing appropriate protective equipment. The respondents, in turn, argued that they had taken reasonable precautions and that the injuries suffered by the appellants were not foreseeable or were not caused by any breach of duty on their part.

In their joint judgment, Hayne and Callinan JJ analysed the principles of negligence, particularly in the context of workplace safety. Their Honours affirmed that an employer owes a duty of care to its employees to take reasonable steps to prevent foreseeable harm. The court considered the state of knowledge regarding the risks of HAVS at the relevant times, examining expert evidence and industry standards. The reasoning focused on whether the respondents' conduct met the standard of a reasonable employer in the circumstances, taking into account the likelihood of injury, the potential severity of the injury, and the burden of taking precautions. The court ultimately found that the respondents had not breached their duty of care, concluding that the evidence did not establish that the specific injuries suffered by the appellants were reasonably foreseeable or that the precautions taken by the respondents were inadequate according to the prevailing standards of the time.

The appeals were dismissed.
