The United States Supreme Court has ruled 7-2 to overturn the federal ban on sports gambling.

"Congress can regulate sports gambling directly, but if it elects not to do so, each State is free to act on its own."

The Professional and Amateur Sports Protection Act did not ban sports gambling nationwide as a matter of federal law, but it said the states were not allowed to permit it. The law had passed in 1992 but Nevada was grandfathered in.

Chris Christie challenged the law, arguing that it violated the Tenth Amendment, which the Supreme Court has said prohibits federal laws that compel states to carry out federal dictates.
