A Portland, Maine jury ordered a Seattle law firm to pay $10.8 million for dumping one set of clients for a more lucrative class-action case. Jurors will return to federal court next week to settle the issue of punitive damages. The award in U.S. District Court is thought to be one of the largest ever granted in a Maine court and could get larger. Judge George Singal told jurors to return next Thursday for a two-day trial on punitive damages.
