The court ruled that victims of the worst oil spill in U.S. history may collect punitive damages from Exxon Mobil Corp., but not as much as a federal appeals court determined.
Justice David Souter wrote for the court that punitive damages may not exceed what the company already paid to compensate victims for economic losses, about $500 million compensation.
Exxon asked the high court to reject the punitive damages judgment, saying it already has spent $3.4 billion in response to the accident that fouled 1,200 miles of Alaska coastline.
A jury decided Exxon should pay $5 billion in punitive damages. A federal appeals court cut that verdict in half.
