The Associated Press is reporting that Exxon Mobil Corp. has decided not to seek certiorari from the portion of the Ninth Circuit’s recent opinion ordering Exxon to pay an additional $470 million in interest on the punitive damages award in the Exxon Valdez case. The story indicates, however, that Exxon may yet want to file a cert. petition challenging the part of the opinion that orders Exxon to bear its own costs on appeal ($70 million, consisting mostly of bond premiums). This 20 year litigation saga isn’t over quite yet.
