The U.S. Supreme Court on Tuesday handed a loss to Tyson Foods Inc (TSN.N) over the company’s challenge to an almost $5.8 million class action judgment in a case won by workers at an Iowa pork-processing facility who contended they were underpaid. The court, in a 6-2 ruling written by conservative Justice Anthony Kennedy, upheld a 2014 appeals court decision in favor of the workers. It was one of three closely watched class action cases to come before the court during its current term, with business interests urging the justices to rein in such litigation.
