Nuclear verdict

A jury award far larger than the proven economic losses would suggest, most often defined as one over $10 million.

Also called: nuclear jury verdict, thermonuclear verdict

A nuclear verdict is a jury award so large it seems out of proportion to the losses proved at trial. There is no legal definition; insurers, defense lawyers and researchers most often use the term for verdicts over $10 million, and some call those over $100 million "thermonuclear." Many involve commercial trucks, but personal auto cases can produce them too.

Large awards usually come from noneconomic damages, such as pain and suffering, and sometimes punitive damages, rather than from medical bills or lost wages. Insurers attribute them to factors such as distrust of corporations, litigation funding, attorney advertising and lawyers who suggest very large numbers to juries. Plaintiff lawyers counter that large awards reflect serious harm. Appeals and settlements often reduce the amount actually paid.

For an individual driver, the lesson is about limits. A judgment above your liability limits can be collected from your personal assets and future wages, which is one reason drivers with assets add an umbrella policy. For everyone, rising verdicts feed social inflation, the growth in claim costs beyond general inflation that insurers cite in rate filings. Tort reform measures, such as limits on certain damages, are the main response states have used. See social inflation and nuclear verdicts: how lawsuits raise premiums.
