The U.S. Supreme Court on Tuesday handed a big win to whistleblowers, ruling that a violation of the federal False Claims Act’s secrecy requirement doesn’t automatically mean a complaint should be dismissed.

The unanimous ruling, delivered by Justice Anthony Kennedy, upheld a decision by the U.S. Court of Appeals for the Fifth Circuit. The appeals court in 2015 refused to dismiss a whistleblower complaint that alleged State Farm Fire & Casualty Co. bilked the U.S. government over how the company processed insurance claims after Hurricane Katrina.
