In a 6-3 opinion, the US Supreme Court struck down a 1992 federal statute that prohibited most states from allowing sports betting. Ruling in favor of the State of New Jersey and against sports leagues including the NCAA, the Court found that the Professional and Amateur Sports Protection Act (PASPA) contained provisions that violated a doctrine known as the anticommandeering rule under the 10th Amendment, meaning that the law represented an unconstitutional overreach into state sovereignty.
