On Monday, in Murphy v. National Collegiate Athletic Association, the United States Supreme Court struck down a federal law that effectively banned sports betting in most states. The Professional and Amateur Sports Protection Act, passed in 1992, prohibited states from authorizing sports gambling. Senator Bill Bradley (D) of New Jersey, a former college and professional basketball star, was one of the sponsors of the bill. The rationale for the law was the purported need to safeguard the integrity of sports. In a 6-3 decision (Justice Alito wrote the majority opinion; Justice Breyer agreed with much of it; Justices Ginsburg and Sotomayor dissented), the Court ruled that the law violated the Tenth Amendment of the U.S. Constitution, which states that the powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. In other words, the Court found that the law violated state sovereignty and opened the door for individual states to pass statutes that would legalize gambling within their borders.
