On May 14, 2018, the Supreme Court ended the federal ban on sports betting by vacating the Professional and Amateur Sports Protection Act (PASPA). The 26-year-old bookmaking prohibition ended after six of the nine justices in Murphy v. NCAA held that the law violated the “anti-commandeering” principle against Congress legislating through the states. The majority reasoned that in prohibiting states from authorizing sports betting, Congress overstepped its constitutional authority by forcing states to legislate against sports betting.
