The four major U.S. pro sports leagues and the NCAA have made another court filing in their efforts to stop New Jersey from allowing legalized sports betting.
The order to show cause was filed Tuesday in federal court in Trenton. The NFL, the NBA, the NHL, Major League Baseball and the NCAA want a judge to temporarily prevent New Jersey's casinos and racetracks from taking sports wagers.
Republican Gov. Chris Christie on Friday signed a law that effectively repeals the state's ban on sports wagering. Monmouth Park racetrack says it plans to accept bets starting Sunday.
A federal judge is expected to rule this week.
The two sides have been fighting in court since 2012, when Christie signed a law authorizing sports betting. Only Nevada offers single-game betting, and three other states are allowed to sell sports parlay pools.
