Ford Motor Company, having prevailed in a 15-year-long class-action suit by truck dealerships, may tax litigation costs jointly and severally against the plaintiffs, a federal judge says.

The May 29 ruling may mark the end of Bayshore Ford Truck Sales v. Ford Motor Co., a litigation saga that began in 1999 when 74 dealers claimed Ford violated a contract to supply them company products when it exited the heavy truck business two years earlier.
