The Supreme Court has handed down a historic ruling today, striking down a federal ban on sports gambling, paving the way for states to legalizing the practice. Writing the majority opinion in the 6-3 decision in Christie v. NCAA, Justice Samuel Alito wrote that the Professional and Amateur Sports Protection Act of 1992 (PASPA), the federal law that prohibited all states from legalizing sports gambling but Nevada, which was grandfathered in, was an “affront to state sovereignty” that violated the Tenth Amendment, which reserves rights to the states. The case was originally brought by former New Jersey Governor Chris Christie, who sought to legalize sports gambling for his state before he left office.
