Walton & Anor v ACN 004 410 833 Limited (formerly Arrium Limited) (in liquidation) & Ors

The applicants, Mr. and Mrs. Walton, sought to recover damages from the respondents, ACN 004 410 833 Limited (in liquidation) (formerly Arrium Limited) and its directors, for losses allegedly suffered as a result of investing in Arrium shares. The dispute concerned the respondents' alleged contraventions of the *Corporations Act 2001* (Cth) and the common law duty of care. The matter was heard by Gageler and Edelman JJ of the High Court of Australia.

The primary legal issue before the High Court was whether the applicants had established a sufficient causal connection between the alleged contraventions by the respondents and the losses they incurred. Specifically, the court had to determine if the applicants' reliance on misleading or deceptive statements made by the respondents was a necessary condition for their decision to invest in Arrium shares, and if such reliance was reasonable in the circumstances.

The High Court's reasoning focused on the principles of causation in tort and statutory claims. Their Honours affirmed that for a claim to succeed, the applicant must demonstrate that the contravening conduct was a material cause of the loss. This involves establishing that the applicant would not have suffered the loss but for the contravening conduct. The court considered the applicants' subjective state of mind and their objective actions in making the investment decision, assessing whether the alleged misrepresentations played a decisive role in their conduct. The principles of *March v Stramare (South Australia) Pty Ltd* and *Henville v North Sydney Council* were central to this analysis, emphasizing the need for a causal link that is not too remote.

The High Court dismissed the applicants' appeal, finding that they had failed to establish the requisite causal connection between the respondents' conduct and their investment losses. The orders of the lower courts were affirmed.
