Ten current and former workers at Summerville-based biotechnology firm ArborGen Inc. won a $53.5 million judgment against their employer and some of the nation's top forest products companies after a judge ruled the companies tricked workers into accepting incentive plan changes that depleted most of their wealth. Judge Edgar Dickson also entered judgments against International Paper, MeadWestvaco - now WestRock - and New Zealand-based Rubicon Inc., as well as some of those forestry companies' board members, following a trial in Dorchester County that lasted nearly three weeks.
