What Is Claim Preclusion (Res Judicata)?
The American legal system demands finality. When a judge or jury issues a final judgment in a lawsuit, that ruling is meant to permanently end the dispute. Claim preclusion (Latin: res judicata, meaning "a matter judged") prevents the losing party from filing a brand-new lawsuit to relitigate the exact same claims.
If a homeowner sues a contractor for $100,000 in damages from a defective roof, and the jury finds in favor of the contractor, the homeowner cannot file the same lawsuit again next year hoping for a different result. The first judgment is final and binding.
The Three Requirements
For claim preclusion to apply in Florida, three conditions must be met:
- Identity of Parties — The same plaintiff and the same defendant (or their legal successors) must be involved in both the first and second lawsuits.
- Identity of Cause of Action — The second lawsuit must arise from the same transaction, occurrence, or set of facts as the first lawsuit. The legal theory does not matter; the factual basis must be the same.
- Final Judgment on the Merits — The first lawsuit must have been fully litigated and resolved with a final judgment. A case that was voluntarily dismissed or settled out of court generally does not trigger claim preclusion.
The "Should Have Been Raised" Rule
Claim preclusion is brutal in its scope. It bars not only the claims that were raised in the first lawsuit, but also all claims that should have been raised. If the homeowner sues the contractor for breach of contract in Lawsuit #1 but forgets to also claim negligence, the homeowner cannot file Lawsuit #2 for negligence. The negligence claim should have been included in the first lawsuit, and the homeowner's failure to include it means it is permanently waived.
