Missouri punitive damage caps mass tort cases come up whenever a big verdict hits the news in St. Louis or Kansas City. Missouri has a law that limits punitive damages, but that limit does not apply to every case.
If you were harmed by a defective drug, a dangerous product, or a toxic chemical, the rules on missouri punitive damage caps mass tort cases could affect how much a jury award is really worth. Punitive damages are extra money meant to punish a company for very bad conduct. They are separate from compensatory damages, which pay for your medical bills, lost wages, and pain. This guide explains how Missouri’s cap works, when courts set it aside, and what changed in 2020.
How Missouri’s Punitive Damage Cap Works
The cap is found in Missouri Revised Statutes Section 510.265. It says punitive damages against a defendant cannot exceed the greater of two amounts. The first is $500,000. The second is five times the net judgment awarded to the plaintiff against that defendant.
For example, say a jury awards you $200,000 in compensatory damages. Five times that amount is $1 million. Because $1 million is greater than $500,000, the punitive award could be capped at $1 million. Now say your compensatory award is only $50,000. Five times that is $250,000. In that case, the $500,000 floor applies instead.
The statute also has built-in exceptions. The cap does not apply when the State of Missouri is the plaintiff. It also does not apply when the defendant pleaded guilty to, or was convicted of, a felony for the same conduct. As a result, a company that faced criminal charges for its conduct may face uncapped punitive damages in civil court.
When Missouri Punitive Damage Caps Mass Tort Cases Do Not Apply
The biggest twist in missouri punitive damage caps mass tort cases is a 2014 ruling. In Lewellen v. Franklin, the Missouri Supreme Court struck down the cap as applied to a fraud claim. The court said the Missouri Constitution protects the right to a jury trial as it existed in 1820. That was the year Missouri adopted its first constitution. Claims that existed under common law back then are protected. A jury’s punitive award on those claims cannot be cut by a statute.
In that case, the jury awarded $1 million in punitive damages. The trial court reduced it under the cap. However, the Supreme Court reversed and restored the full $1 million. The court relied on its earlier 2012 ruling in Watts v. Lester E. Cox Medical Centers. That case struck down caps on non-economic damages in medical malpractice cases.
The cap still has some life, though. In a 2022 decision, the Missouri Supreme Court upheld applying the cap to a claim created by statute. Claims created by the legislature did not exist in 1820. Therefore, the legislature can limit the remedies for them. In most cases, the key question becomes this: is your claim rooted in common law, or was it created by a statute?
This matters a great deal for missouri punitive damage caps mass tort cases. Most mass tort claims rely on traditional common-law theories. These include negligence, product liability, failure to warn, and fraud. Typically, plaintiffs argue that these claims fall under the Lewellen rule. By contrast, claims under the Missouri Merchandising Practices Act or the Missouri Human Rights Act are statutory. Those claims are more likely to face the cap.
| Type of Claim | Origin | Is the Cap Likely to Apply? |
|---|---|---|
| Fraud / misrepresentation | Common law | No (Lewellen, 2014) |
| Negligence / product liability | Common law | Often argued no |
| Merchandising Practices Act | Statute | Likely yes |
| Human Rights Act (discrimination) | Statute | Yes (separate caps in Section 510.265.2) |
| Defendant convicted of a related felony | Any | No (statutory exception) |
The 2020 Law That Changed How Punitive Damages Are Sought
In 2020, Missouri passed Senate Bill 591. It did not raise or lower the dollar cap. Instead, it made punitive damages harder to request and prove. The law applies to cases filed on or after August 28, 2020. It is not retroactive.
First, plaintiffs can no longer ask for punitive damages in their first court filing. They must file a written motion asking the judge for permission. That motion is generally due at least 120 days before the final pretrial conference or trial. It must include evidence showing a reasonable basis for punitive damages. The judge typically has 45 days after a hearing to rule.
Second, the law raised the bar for proof. A plaintiff must show by clear and convincing evidence that the defendant either intended to cause harm without just cause, or acted with deliberate and flagrant disregard for safety. Clear and convincing evidence is a higher standard than “more likely than not.” Third, discovery into a company’s finances is allowed only after the judge approves a punitive damages claim. As a result, missouri punitive damage caps mass tort cases now involve a gatekeeping step before the cap question even arises.
Real Verdicts: What Happened in Missouri Mass Torts
The most famous example is the Johnson & Johnson talc case, Ingham v. Johnson & Johnson. In 2018, a St. Louis jury awarded 22 women about $4.69 billion. That included roughly $4.14 billion in punitive damages. The women claimed asbestos in talc powder caused their ovarian cancer.
In 2020, the Missouri Court of Appeals cut the award to about $2.1 billion. That included $500 million in compensatory damages and about $1.62 billion in punitive damages. However, the cut was not driven by the statutory cap. The court dismissed claims from some out-of-state plaintiffs against one J&J entity. Notably, $1.62 billion is less than five times the $500 million compensatory award. So the award fit within the cap’s formula anyway. The U.S. Supreme Court declined to hear J&J’s appeal in June 2021.
This example shows a key point about missouri punitive damage caps mass tort cases. When compensatory damages are large, the “five times” formula allows huge punitive awards. Federal law also plays a role. The U.S. Supreme Court ruled in State Farm v. Campbell (2003) that punitive awards above a single-digit ratio to compensatory damages may violate due process. In most cases, that federal limit is similar to Missouri’s five-times rule.
What You Should Do If You Have a Missouri Mass Tort Claim
First, keep detailed records. Save medical records, product packaging, receipts, and prescription histories. Compensatory damages drive the cap formula. As a result, strong proof of your actual losses can raise the ceiling on punitive damages.

Second, act quickly. Missouri’s statute of limitations for most personal injury claims is five years. However, wrongful death claims typically have a three-year limit. Also, the 120-day deadline for punitive damage motions means your lawyer needs evidence early.
Third, ask how your claim is framed. A lawyer handling missouri punitive damage caps mass tort cases should explain whether your claims are common-law or statutory. That choice can decide whether the cap applies at all. Fourth, ask about venue. Missouri changed its joinder and venue rules in 2019. Out-of-state plaintiffs now have a harder time filing in St. Louis City unless their claims have a real Missouri connection.
Finally, remember that many mass torts are consolidated in federal multidistrict litigation (MDL). If your case is sent to an MDL, state law on damages may still apply at trial. Typically, the law of the state where the injury happened controls. For example, a Missouri resident injured in Missouri will usually have Missouri damage rules apply.
Frequently Asked Questions
What is the punitive damage cap in Missouri?
Missouri caps punitive damages at the greater of $500,000 or five times the net judgment. However, the Missouri Supreme Court ruled in 2014 that the cap cannot reduce awards on common-law claims like fraud. As a result, missouri punitive damage caps mass tort cases often turn on the type of claim filed.
Does the cap apply to product liability and drug injury lawsuits?
It depends on how the claim is framed. Typically, negligence and failure-to-warn claims are rooted in common law, so plaintiffs argue the cap does not apply. By contrast, statutory consumer protection claims are more likely to be capped.
Can I ask for punitive damages when I first file my lawsuit?
No, not for cases filed after August 28, 2020. You must get the judge’s permission through a written motion. In most cases, that motion is due at least 120 days before trial or the final pretrial conference.
Why are Missouri verdicts sometimes so large?
Large compensatory awards raise the five-times ceiling. For example, the J&J talc case had $500 million in compensatory damages, which allowed up to $2.5 billion in punitive damages. That is why missouri punitive damage caps mass tort cases can still produce billion-dollar results.
