After years of bouncing back and forth in appeals courts, the ExxonValdez litigation may finally have reached the end of the line in the9th U.S. Circuit Court of Appeals — and a potential resolution.

In December 2006, a three-judge 9th Circuit panel reduced an Alaskajury’s award to the fishermen and residents affected by the 1989 oilspill in Prince William Sound from $5 billion to $2.5 billion.Last week, the court reaffirmed the $2.5 billion award and deniedExxon’s petition for a panel rehearing.
