Betting on sports is an activity that has unarguably increased in popularity over the last several decades. Seeking to address instances of illegal sports wagering within its borders and to improve its economy, the State of New Jersey has sought to license gambling on certain professional and amateur sporting events. A conglomerate of sports leagues, displeased at the prospect of State-licensed gambling on their athletic contests, has sued to halt these efforts. They contend, alongside the United States as intervening plaintiff, that New Jersey’s proposed law violates a federal law that prohibits most states from licensing sports gambling, the Professional and Amateur Sports Protection Act of 1992 (PASPA), 28 U.S.C. § 3701 et seq.
