Where more than one person contributes to causing a single, indivisible harm, the law does not require the injured plaintiff to sue each contributor separately for a proportionate share; it instead allows recovery of the full amount from any one of them, leaving questions of internal apportionment to be resolved separately among the wrongdoers themselves.
Legal Framework
| Concept | Scope |
|---|---|
| Joint tortfeasors | Two or more persons whose combined or concerted conduct causes a single, indivisible harm to the plaintiff |
| Several (independent) tortfeasors | Two or more persons whose separate, independent wrongful acts each contribute to the plaintiff's harm, without acting in concert |
| Contribution | The right of a tortfeasor who has paid more than their fair share of damages to recover a proportionate contribution from co-tortfeasors |
Who Qualifies as a Joint Tortfeasor
Persons are treated as joint tortfeasors where their liability arises from a common design or concerted action toward causing the same harm (such as persons acting together in a common plan resulting in the plaintiff's injury), or where they share a common duty whose combined breach causes a single, indivisible harm (such as an employer and employee, where the employee's tort and the employer's vicarious liability for it are treated as jointly arising from the same wrongful conduct). Why this joint characterisation matters practically: Since the harm caused is indivisible (it cannot meaningfully be separated into distinct portions attributable to each specific contributor), the law does not require the plaintiff to prove and separately recover a specific proportionate share from each tortfeasor; the plaintiff may instead recover the full amount of the single, indivisible harm from any one of the joint tortfeasors, who then bears the burden of seeking contribution from their co-tortfeasors, rather than leaving the plaintiff to bear the risk and burden of proving each contributor's precise individual share.
The Koursk (1924): This case addressed the distinction between joint tortfeasors (acting pursuant to some common design or shared duty) and several, independent tortfeasors (whose separate, independent acts happen to combine to produce a single harm, without any genuine concert or common design between them), clarifying that this distinction affects specific procedural and substantive consequences, such as the effect of a settlement or release with one tortfeasor on the liability of the others.
Several (Independent) Tortfeasors Contrasted
Where two or more persons, acting entirely independently without any common design or concerted action, each separately contribute some wrongful conduct that combines to produce a single, indivisible harm (such as two separate drivers, each independently negligent, whose combined negligence causes a single collision and injury), they are treated as several, independent tortfeasors rather than joint tortfeasors in the strict technical sense, though the practical consequence for the plaintiff's ability to recover the full amount from either remains broadly similar in most jurisdictions today, given modern statutory and common law developments extending similar principles of joint and several liability to this situation as well.
The Right of Contribution
Where a plaintiff recovers the full amount of damages from one tortfeasor among several jointly (or severally) liable for the same indivisible harm, that tortfeasor who has borne this full payment has a right to seek contribution from the other co-tortfeasors, recovering from each their fair, proportionate share of the total liability, generally assessed according to their relative degree of fault or responsibility for the harm.
Why the law grants this contribution right, rather than leaving the paying tortfeasor to bear the entire loss alone: Since each co-tortfeasor genuinely contributed to causing the harm, allowing the tortfeasor who happened to be sued (and who paid the full amount, perhaps simply because the plaintiff chose to pursue them specifically, or because they were more easily located or had greater immediate assets) to recover proportionate contribution from the others ensures the ultimate financial burden is fairly distributed according to actual relative responsibility, rather than depending arbitrarily on which specific tortfeasor the plaintiff happened to choose to sue first or most vigorously.
Illustrations
-
Joint tortfeasors, common design: Two persons, acting together pursuant to a shared plan, jointly assault a third person, each striking blows contributing to the overall injury. Since they acted with a common design toward causing this single harm, they are joint tortfeasors, and the injured plaintiff may recover the full amount of damages from either one of them, without needing to prove which specific blows caused which specific portion of the overall injury.
-
Employer and employee, joint liability through vicarious liability: An employee, while driving negligently within the course of employment, injures a pedestrian. The employer's vicarious liability and the employee's own personal liability both arise from this single wrongful conduct, and the pedestrian may recover the full amount from either the employer or the employee (or both), this relationship being treated for these purposes analogously to joint tortfeasors.
-
Contribution sought after full payment: Two co-tortfeasors, having jointly caused a single harm through their combined negligence, are sued by the plaintiff, who recovers the full damages award from only one of them (perhaps because that tortfeasor had more readily available assets). That tortfeasor, having paid the full amount, may subsequently seek contribution from the other co-tortfeasor, recovering a proportionate share reflecting that co-tortfeasor's relative degree of fault for the overall harm.

Key Cases
The Koursk (1924) The-Koursk-1924 Issue: The distinction between joint tortfeasors, acting pursuant to a common design, and several, independent tortfeasors, whose separate acts happen to combine to produce a single harm. Rule: Joint tortfeasors are those acting pursuant to a common design or shared duty; several tortfeasors act entirely independently, though both categories may face similar practical consequences regarding the plaintiff's ability to recover the full amount from any one of them. Held: The court's analysis clarified this important distinction and its specific procedural and substantive consequences.
Distinctions
| Basis | Joint Tortfeasors | Several (Independent) Tortfeasors |
|---|---|---|
| Basis of liability | Common design or shared duty toward the same harm | Independent, separate acts that happen to combine to produce a single harm |
| Example | Persons acting together in a common assault plan | Two separately negligent drivers whose combined negligence causes one collision |
| Plaintiff's recovery | Full amount recoverable from any one | Full amount generally recoverable from any one, under modern principles |
Flashcards
Q: What are joint tortfeasors? A: Two or more persons whose combined or concerted conduct, pursuant to a common design or shared duty, causes a single, indivisible harm.
Q: Can a plaintiff recover the full amount of damages from just one of several joint tortfeasors? A: Yes, without needing to prove each tortfeasor's specific individual share of the harm.
Q: What distinction did The Koursk address? A: The distinction between joint tortfeasors (common design) and several, independent tortfeasors (separate, independent acts combining to produce harm).
Q: What right does a tortfeasor who pays the full amount of damages have against co-tortfeasors? A: A right of contribution, recovering a proportionate share from each co-tortfeasor based on their relative fault.
Q: How does the employer-employee relationship connect to joint liability principles? A: Through vicarious liability, both the employer and employee are liable for the same wrongful conduct, and the plaintiff may recover the full amount from either.
Exam Scenario
Three friends, acting together pursuant to a jointly planned prank, cause damage to a shopkeeper's property, though it is genuinely impossible to determine which specific friend's actions caused which specific portion of the total damage. The shopkeeper sues only one of the three friends, who has the most readily available assets, and recovers the entire damages award from him. Advise this friend on his rights against the other two.
Approach: Confirm that since the three friends acted pursuant to a common design (the jointly planned prank), they qualify as joint tortfeasors, meaning the shopkeeper was entitled to recover the full damages award from any one of them without needing to prove each individual's specific contribution to the total damage, precisely because the harm is indivisible among their combined conduct. Advise the friend who paid the full amount that he now holds a right of contribution against the other two friends, entitling him to recover from each a proportionate share of the total damages paid, generally assessed according to their relative degree of responsibility for the overall harm, ensuring the financial burden is fairly distributed among all three participants rather than falling entirely and permanently on the one friend the shopkeeper happened to choose to sue.
