# Duty of care in novel cases: *Sullivan v Moody* URL: https://www.barristerai.com.au/principles/sullivan-v-moody Last updated: 2026-11-09 Publisher: Barrister AI Australian law has no single formula for deciding whether a duty of care exists in a new category of case. *Sullivan v Moody* (2001) 207 CLR 562 explains why, and points courts to the features of the relationship that matter. ## In short - Foreseeability of harm is necessary but not sufficient for a duty of care. - The High Court rejected proximity as a unifying test, and did not adopt the English three-stage test from *Caparo Industries plc v Dickman* [1990] 2 AC 605. - A duty will not be imposed where it would be incoherent with another legal duty or statutory function. - Courts reason from the salient features of the relationship, often using the list in *Caltex Refineries (Qld) Pty Ltd v Stavar* [2009] NSWCA 258. ## The case Fathers suspected of child sexual abuse sued the doctors and social workers who had examined their children and reported on the allegations. In *Sullivan v Moody* [2001] HCA 59 the High Court held that no duty of care was owed to the suspected parent. A duty to the suspect would conflict with the professionals’ duty to protect the child, and with the statutory scheme under which they acted. ## Coherence The decisive reason was incoherence: the law should not impose a duty that would pull a person in a direction inconsistent with another duty they owe, or with the purpose of a statutory scheme. Coherence reasoning is now routinely applied to public authorities and professionals acting under statute. ## The salient features approach In novel cases, intermediate appellate courts reason from a multi-factor list of salient features. In *Caltex Refineries (Qld) Pty Ltd v Stavar* [2009] NSWCA 258 Allsop P collected them, including: - the foreseeability of harm and its nature; - the degree and nature of control able to be exercised by the defendant; - the plaintiff’s vulnerability, and their ability to protect themselves; - the degree of reliance, and any assumption of responsibility; - the proximity of the parties; - the existence of a category of relationship in which a duty is recognised; - the nature of the activity, and the content of any statutory or other legal obligations; - consistency and coherence with other legal principles, and policy considerations. ## Frequently asked questions ### What test for duty of care applies in Australia? There is no single test. In established categories the duty is recognised; in novel cases courts reason from the salient features of the relationship, with foreseeability necessary but not sufficient, and duties incoherent with other obligations rejected. ### Does Australia use the Caparo test? No. In Sullivan v Moody the High Court declined to adopt the three-stage test from Caparo Industries plc v Dickman [1990] 2 AC 605. ## Sources - Sullivan v Moody [2001] HCA 59; (2001) 207 CLR 562: https://www.barristerai.com.au/case/2001/hca/59 - Caltex Refineries (Qld) Pty Ltd v Stavar [2009] NSWCA 258: https://www.barristerai.com.au/case/2009/nswca/258 General information, not legal advice.
