Terms used\n\nIn this Act, subject to the context —\n\n  action includes an arbitration;\n\n  court includes an arbitrator;\n\n  defendant includes —\n\n(a) a party to an action against whom a counter‑claim is made in the action; and\n\n(b) a person for whose act the defendant or such party was vicariously responsible;\n\n  Fatal Accidents Act means the Imperial Act 9 and 10 Victoriae Cap. 93 (as adopted) as amended by Act No. 37 of 1900, or any Act now or hereafter in force in substitution for or amending the same 1;\n\n  negligence includes breach of statutory duty;\n\n  plaintiff includes —\n\n(a) a party to an action who makes a counter‑claim in the action; and\n\n(b) a person for whose act the plaintiff or such party was vicariously responsible;\n\n  workers’ compensation includes all sums and benefits recoverable under the *Workers Compensation and Injury Management Act 2023*.\n\n[Section 3 amended: No. 42 of 2004 s. 175; No. 21 of 2023 s. 709(2).]\n\n## Part 2 — Contributory negligence — Amendment of the law\n\n[Heading inserted: No. 19 of 2010 s. 46(3).]\n\n##### 3A. Claims etc. founded on etc. negligence, construction of references to\n\nIn sections 4 and 6 —\n\n(a) a reference to a claim or action founded on or resulting from negligence includes a reference to a claim or action founded on or resulting from a breach of a contractual duty of care that is concurrent with and coextensive with a duty of care in tort; and\n\n(b) references to negligence have a corresponding meaning so far as they relate to a defendant.\n\n[Section 3A inserted: No. 17 of 2003 s. 4.]\n\n##### 4. Contributory negligence, court may reduce plaintiff’s damages\n\n(1) Whenever in any claim for damages founded on an allegation of negligence the court is satisfied that the defendant was guilty of an act of negligence conducing to the happening of the event which caused the damage then notwithstanding that the plaintiff had the last opportunity of avoiding or could by the exercise of reasonable care, have avoided the consequences of the defendant’s act or might otherwise be held guilty of contributory negligence, the defendant shall not for that reason be entitled to judgment, but the court shall reduce the damages which would be recoverable by the plaintiff if the happening of the event which caused the damage had been solely due to the negligence of the defendant to such extent as the court thinks just in accordance with the degree of negligence attributable to the plaintiff.\n\n(1A) Subsection (1) shall not operate to defeat any defence arising under a contract.\n\n(1B) Where any contract or enactment providing for the limitation of liability is applicable to the claim the amount of damages recoverable by virtue of subsection (1) shall not exceed the maximum limit applicable.\n\n(2) The provisions of subsection (1) shall apply to actions brought —\n\n(a) under the Fatal Accidents Act; or\n\n(b) by virtue of section 4 of the *Law Reform (Miscellaneous Provisions) Act 1941*, in respect of a claim made for the benefit of the estate of a deceased person in consequence of the death of the deceased as the result of the negligence of another person;\n\nand for that purpose shall be read and construed as if the following words were inserted in the following relative positions in the subsection:\n\n(c) after the words “notwithstanding that the plaintiff” insert the words “or the deceased person in respect of whose death or for the benefit of whose estate the claim is brought or some other person for whose acts the deceased person was responsible”;\n\n(d) after the words “recoverable by the plaintiff” insert the words “or by the persons for whose benefit the claim is made or by the estate of the deceased person in respect of which the claim is made”.\n\n(3) The provisions of subsection (1) shall apply notwithstanding that one or more of the parties to the action might by reason of such negligence be held guilty of a punishable offence.\n\n(4) Where any case to which subsection (1) applies is tried with a jury, the jury shall determine the total damages which would have been recoverable if the party claiming the damages had not been negligent and the extent to which those damages are to be reduced.\n\n[Section 4 amended No. 19 of 2010 s. 51.]\n\n##### 5. Effect of s. 4(1) where 2 or more persons are liable to pay damages\n\n(1) Where by virtue of section 4(1), 2 or more persons are liable to pay damages or would if sued have been liable to pay damages, judgment recovered against one of them shall not be a bar to an action or actions against any other or others of them but in such case —\n\n(a) the provisions of section 7(1)(b) shall apply with the necessary adaptations;\n\n(b) all or any of such persons may as between themselves and any other or others of them claim and cover contribution and the provisions of section 7(1)(c) and of section 7(2) shall apply with the necessary adaptations.\n\n(2) Where 2 or more such persons are sued jointly, the court may order contribution as between themselves and the provisions of section 7(1)(c) and of section 7(2) shall apply with the necessary adaptations.\n\n[Section 5 amended No. 19 of 2010 s. 51.]\n\n##### 6. Effect of s. 4(1) on party’s right to recover workers’ compensation\n\n(1) Where a plaintiff in any action for damages founded on negligence would have been entitled when he commenced such action to take proceedings under the *Workers Compensation and Injury Management Act 2023*, against any defendant or defendants in the action to recover workers’ compensation and by reason of section 4(1) of this Act, the damages recoverable by him are reduced and the reduced amount is less than he would have been entitled to recover as workers’ compensation, the plaintiff shall be entitled to recover judgment against such defendant or defendants for the sum to which he would be entitled as workers’ compensation: Provided that the court shall deduct therefrom all the costs which have been unnecessarily caused by the plaintiff bringing the action instead of taking proceedings under the *Workers Compensation and Injury Management Act 2023*.\n\n(2) Where a person liable to pay workers’ compensation has paid such compensation to a worker or his dependants in a case where the worker or any of his dependants or the personal representatives of the worker would have had a right independently of the *Workers Compensation and Injury Management Act 2023*, to recover reduced damages against a third party by virtue of section 4(1) of this Act, the person who has paid the workers’ compensation shall have a right of indemnity against the third party and the *Workers Compensation and Injury Management Act 2023* section 22 applies but so that the sum recoverable by way of indemnity shall be reduced in the same proportion as the damages would be reducible under section 4(1) of this Act.\n\n[Section 6 amended: No. 42 of 2004 s. 175; No. 21 of 2023 s. 650 and 709(2).]\n\n## Part 3 — Contribution between tortfeasors\n\n[Heading inserted: No. 19 of 2010 s. 46(3).]\n\n##### 7. Rules applicable if there are 2 or more tortfeasors\n\n(1) Subject to Part 1F of the *Civil Liability Act 2002*, where damage is suffered by any person as the result of a tort —\n\n(a) judgment recovered against any tortfeasor liable in respect of that damage shall not be a bar to an action against any other person who would, if sued, have been liable as a joint tortfeasor in respect of the same damage;\n\n(b) if more than one action is brought in respect of that damage by or on behalf of the person by whom it was suffered, or for the benefit of the estate, or of the wife, husband, parent or child of that person, against tortfeasors liable in respect of the damage (whether as joint tortfeasors or otherwise) the sums recoverable under the judgments given in those actions by way of damages shall not in the aggregate exceed the amount of the damages awarded by the judgment first given: and in any of those actions, other than that in which judgment is first given, the plaintiff shall not be entitled to costs unless the court is of opinion that there was reasonable ground for bringing the action;\n\n(c) any tortfeasor liable in respect of that damage may recover contribution from any other tortfeasor who is or would if sued have been liable in respect of the same damage whether as a joint tortfeasor or otherwise but so that no person shall be entitled to recover contribution under this section from any person entitled to be indemnified by him in respect of the liability for which contribution is sought.\n\n(1A) A person shall be entitled to be indemnified within the meaning of subsection (1)(c) —\n\n(a) if his complicity in the tort arose from fraud or misrepresentation practised on him by the person from whom the indemnity is sought so that he honestly believed and had no reasonable cause to suspect the truth of the matters represented to him and would not have been liable in tort if such matters had been true;\n\n(b) where the act was not clearly illegal or tortious in itself and the person seeking indemnity had no knowledge when the tort was committed of the true legal character of the act;\n\n(c) where he is responsible on grounds of vicarious liability as for example in the case of master and servant or as a member of a partnership where the act was done without his connivance, knowledge or express authority.\n\n(1B) Except in the case of an indictable offence arising out of some negligent act or omission, no contribution may be claimed by a person who is responsible for damages in tort if in the circumstances of the case he is or might be found guilty of any indictable offence (including an indictable offence punishable on summary conviction).\n\n(2) In any proceedings for contribution under this section the amount of the contribution recoverable from any person shall be such as may be found by the court to be just and equitable; and the court shall have power to exempt any person from liability to make contribution, or to direct that the contribution to be recovered from any person shall amount to a complete indemnity.\n\n(3) For the purposes of this section —\n\n(a) the expressions parent and child have the same meanings respectively as they have for the purposes of the Fatal Accidents Act;\n\n(b) the reference in this section to the judgment first given shall, in a case where that judgment is reversed on appeal, be construed as a reference to the judgment first given which is not so reversed and, in a case where a judgment is varied on appeal, be construed as a reference to that judgment as so varied.\n\n[Section 7 amended: No. 58 of 2003 s. 14; No. 19 of 2010 s. 51.]\n\n## Part 4 — General\n\n[Heading inserted: No. 19 of 2010 s. 46(3).]\n\n##### 8. Person not liable due to limitation period not entitled to benefit of s. 4(1)\n\nWhere one person avoids liability to another person by reason of any statute of limitation applicable in the circumstances such first‑mentioned person shall not be entitled to recover any damages from the other by virtue of section 4(1).\n\n##### 9. Application of this Act\n\nThis Act shall apply only where the acts or omissions giving rise to a claim in damages occur after its commencement.\n\n![dline]()\n\nNotes\n\nThis is a compilation of the *Law Reform (Contributory Negligence and Tortfeasors’ Contribution) Act 1947* and includes amendments made by other written laws.

Fixes the \"all or nothing\" rule for contributory negligence**\n\nBefore this law, if you were even slightly careless yourself (say, 5% at fault) and someone else was mostly to blame (95% at fault), you got nothing. The court could wipe out your entire claim.\n\nNow, the court looks at how much each person was at fault and reduces your damages accordingly. If you're 30% to blame, you get 70% of your damages. This is called **\"apportionment\"** (sharing out the blame).\n\n**2. Allows wrongdoers to share the bill fairly**\n\nIf two or more people are responsible for your injury, this law lets them sort out between themselves who pays what. Previously, if you sued one wrongdoer and got paid, you couldn't sue the others—even if they were also to blame.\n\nNow:\n- You can sue multiple wrongdoers\n- They can claim **\"contribution\"** (a share of the costs) from each other\n- The court decides what's \"just and equitable\" (fair) between them\n\n**Who it affects:**\n- Anyone injured by negligence (carelessness) in WA\n- Employers and workers (it interacts with workers' compensation)\n- Multiple defendants in accident cases (like car crashes with several at-fault drivers)\n\n**Why it matters:**\nIt stops the harsh old rule where a tiny bit of carelessness on your part meant losing everything.

Before reforms like this Act, if you were even slightly to blame for your own injury, you could receive *nothing* in compensation. This Act changed that so courts can instead *reduce* your compensation by the percentage you were at fault — a much fairer outcome.\n\n2. **Contribution between wrongdoers (tortfeasors)** — A \"tortfeasor\" is simply a person who has done something legally wrong that caused harm to someone else. If multiple people were responsible for the same harm, this Act allows them to share the financial burden fairly between themselves, rather than one person being stuck paying everything.\n\n**Who does this affect?**\n- Anyone injured in an accident (car crashes, workplace injuries, slip and falls) where they may have partly contributed to what happened\n- Businesses, employers, or individuals who share responsibility for causing harm to someone\n- Lawyers and courts handling civil compensation claims in Western Australia\n\n**Why does it matter?**\nBefore laws like this existed, the all-or-nothing approach to blame was often deeply unfair.

Instead of automatically barring the plaintiff from recovery where the plaintiff was also negligent, the court reduces the plaintiff’s damages in proportion to the plaintiff’s share of fault (see section 4).  \n\n- The Act also governs how multiple people who are jointly or severally liable (tortfeasors) sort out who pays what. A tortfeasor who pays can seek contribution from other tortfeasors, and the court decides what is just and equitable (see section 7). The Act preserves the ability to sue others even if judgment has already been recovered against one tortfeasor (see section 7(1)(a) and section 5).  \n\n### Who it affects\n\n- Plaintiffs who claim damages for negligence or for a breach of a contractual duty of care that overlaps with a tort duty (see section 3A).  \n- Defendants and other tortfeasors who may be required to pay damages and/or contribute to payments made by co‑tortfeasors (see sections 4, 5 and 7).  \n- Employers and workers’ compensation payers where workers’ compensation interacts with a negligence claim (see section 6).  \n- Courts and arbitrators, because “court” and “action” are defined to include arbitrators and arbitrations (see section 3).  \n\n### How it works mechanically (key provisions)\n\n- Reduction of damages for contributory negligence: If the court finds both parties negligent, it reduces the damages the plaintiff would otherwise recover to the extent it thinks just, reflecting the plaintiff’s share of blame (section 4(1)). If a jury tries the case, the jury determines the total damages and the reduction (section 4(4)).  \n\n- Contract and caps: Subsection 4(1A) preserves any contract‑based defences (so the statutory reduction does not defeat contractual defences). If a contract or statute limits liability, the reduced damages cannot exceed that limit (section 4(1B)).  \n\n- Application to fatal‑injury claims: The reduction rule also applies to actions under the Fatal Accidents Act or survivorship claims for a deceased person, with wording adjustments to treat the deceased and beneficiaries as plaintiffs (section 4(2)).  \n\n- Multiple tortfeasors and contribution: A tortfeasor who pays may recover contribution from others who are liable for the same damage; the court decides what is just and equitable and may exempt someone or grant full indemnity (section 7(1)(c) and 7(2)). Aggregate recoveries across multiple judgments cannot exceed the amount of the first judgment (section 7(1)(b)).  \n\n- Indemnity and exceptions: Some persons are entitled to indemnity (for example, someone misled by fraud, or vicariously liable persons who did not authorize the wrongful act) (section 7(1A)). A person who may be liable for an indictable offence generally cannot claim contribution (section 7(1B)).  \n\n- Workers’ compensation interplay: If a plaintiff’s reduced common‑law damages are less than the workers’ compensation they could have taken, the plaintiff can recover the workers’ compensation amount instead, but the court can deduct costs that were unnecessarily incurred by suing instead of using the workers’ compensation scheme (section 6(1)). A workers’ compensation payer who has paid may have an indemnity claim against the third party, reduced proportionately to reflect the statutory reduction under section 4 (section 6(2)).  \n\n- Limitation‑period safeguard: A person who avoids liability because a limitation statute bars the claim may not then use section 4(1) to recover damages from the other party (section 8).  \n\n- Definitions and scope: “Negligence” includes breach of statutory duty and references to claims founded on negligence include concurrent contractual duties of care (sections 3 and 3A). The Act applies only to wrongful acts or omissions occurring after the Act’s commencement (section 9).  \n\n### Explicit stated purpose and testing of that purpose against costs and incentives\n\n- The Act’s operative changes are: replacing a total bar to recovery for contributory negligence with proportional reduction (section 4), and setting rules for contribution among tortfeasors (section 7). The statutory language presents these as mechanical changes to how liability and recovery are apportioned.  \n\n- Who pays and who decides: Courts (or juries where provided) decide apportionment of blame and reductions under section 4 and apportionment of contribution under section 7 (see sections 4(4) and 7(2)). Defendants and tortfeasors ultimately pay damages, subject to any contributions they can recover from co‑tortfeasors (sections 4, 5 and 7). Workers’ compensation payers may pay first but then seek indemnity from third parties (section 6(2)).  \n\n- Costs and incentives created by the mechanics:  \n  - Plaintiffs face a choice about suing at common law or pursuing workers’ compensation if available; section 6 creates an incentive to compare expected recoveries before proceeding because a court may award workers’ compensation instead and deduct costs that were unnecessary.  \n  - Defendants may still be liable even when the plaintiff had the last opportunity to avoid harm; liability is adjusted rather than defeated (section 4(1)). This changes defensive strategy and settlement dynamics because apportionment becomes the focus rather than an absolute defence.  \n  - Tortfeasors who pay can pursue contribution from others, which can shift litigation among co‑defendants and affect settlement bargaining (section 7(1)(c)).  \n\n- Compliance and administrative burden:  \n  - The court’s broad discretion to decide what is “just in accordance with the degree of negligence” (section 4(1)) and to apportion contributions “just and equitable” (section 7(2)) means cases require factual assessment and judicial exercise of judgment, which can increase litigation complexity and costs.  \n  - Cross‑references to other statutes (for example, workers’ compensation legislation and Part 1F of the Civil Liability Act 2002) require parties and courts to resolve interactions across multiple laws (see sections 6 and 7(1) note).  \n\n- Discretion and limits on private choice: The Act leaves significant discretion to courts and juries to quantify fault and set contribution; parties cannot contract out of statutory limits on recoverable damages where a statutory or contractual cap applies (section 4(1B)), and section 4(1A) preserves contractual defences where they exist.  \n\n### Implementation and risk notes from the text\n\n- The Act contains explicit exceptions that limit its effects: contract defences remain (section 4(1A)); contribution is unavailable to persons potentially liable for indictable offences in most circumstances (section 7(1B)); limitation‑period avoidance prevents invoking section 4(1) against another (section 8).  \n\n- The Act was amended over time to add or clarify coverage (for example, allowing references to concurrent contractual duties and updating interaction with workers’ compensation legislation); these amendments change the operational scope of the Act (see section 3A and the compilation/notes).  \n\nFor quick reference, read these sections first: section 4 (reduction for contributory negligence), section 7 (contribution between tortfeasors), and section 6 (workers’ compensation interaction)."}},"importantCases":[],"_links":{"self":"/api/acts/law-reform-contributory-negligence-and-tortfeasors-contribution-act-1947","history":"/api/acts/law-reform-contributory-negligence-and-tortfeasors-contribution-act-1947/history","analysis":"/api/acts/law-reform-contributory-negligence-and-tortfeasors-contribution-act-1947/analysis","conflicts":"/api/acts/law-reform-contributory-negligence-and-tortfeasors-contribution-act-1947/conflicts","importantCases":"/api/acts/law-reform-contributory-negligence-and-tortfeasors-contribution-act-1947/important-cases","documents":"/api/acts/law-reform-contributory-negligence-and-tortfeasors-contribution-act-1947/documents"}}
