The NCAA and MLB, NBA, NFL and NHL have filed a federal lawsuit against New Jersey state officials in an effort to stop sports gambling.
According to the NCAA website, a complaint was filed against the state officials in federal court that aims to stop the state from implementing sports betting on professional and collegiate contests.
"The leagues and the NCAA assert that the state’s recently announced decision to offer sports betting violates long-standing federal law. The Professional and Amateur Sports Protection Act (“PASPA”) became law in 1992 and prohibits states from operating a lottery or betting scheme based on pro or college games."
Apparently, back in 1993 a one year window of opportunity was provided for New Jersey to authorize sports betting, but the state declined that opportunity and has since been barred by federal law from participating in sports betting.
