Have you ever asked yourself: What if someone sued you for breach of contract, and after losing the case, they came back months later with new evidence, trying to get the same issue re-litigated? Doesn’t sound fair right? That’s where res judicata comes in.
What is res judicata?
Res judicata is the legal principle that a cause of action may not be relitigated once there has been a final judgment on the merits. It is often referred to as cause of action estoppel or claim estoppel. The doctrine, which derives from the Latin of “a matter judged”, is designed to prohibit parties from relitigating a claim or a defence of something that has already been adjudicated. The idea of res judicata emerged from the English common law and is meant to ensure the finality of judgments and conserve judicial resources.
When does res judicata apply?
Res judicata applies when a final and conclusive judgment has been made by a Court with proper jurisdiction. If the same issue arises in future proceedings, even in different Tribunals, the judgment from the earlier case can be pleaded as an estoppel, preventing re-litigation. This applies if the cause of action and the issues are identical, the judgment was final and conclusive, and the tribunal had proper jurisdiction.
Why is res judicata Important?
The principle of res judicata ensures the finality of legal decisions, reducing unnecessary litigation and helping to maintain public confidence in the legal system. It is an essential part of ensuring efficiency and fairness in the judicial process.
In practice, res judicata prevents a party from “shopping” for a more favourable Court decision or from trying to re-litigate a matter that has already been thoroughly examined. It underscores the importance of bringing all relevant claims before the Court in the initial suit rather than trying to piecemeal the issue in future actions.
An issue that commonly arises in insurance recoveries is the failure of the plaintiff to distinguish between insured and uninsured losses. For example, an insured person under a motor vehicle insurance policy may be covered for damage to the insured vehicle and third-party loss/damage, but not for costs such as a replacement hire vehicle. Once a court has determined the scope of the insurance coverage, res judicata would prevent the plaintiff from re-litigating the claim for the unclaimed uninsured loss in a subsequent claim.
