Baseball's Latest Legal Tangle Is With Umpires Union
The commissioner of Major League Baseball is suing the umpires union over a dispute with the union president and the way games have been called this year. This action follows on the heals of a suit brought against the commissioner and his office by the union charging they violated the Federal racketeering act. The piling of litigation stems from a lawsuit filed to prevent the World Umpires Association from having an arbitrator hear a grievance over discipline the union president received. The union claims the grievance was based on baseball’s use of technology to evaluate members performance during games.
