NBC News reports:
The U.S. Supreme Court acted Monday to bust Nevada’s monopoly on legal sports betting, allowing more states to get in on the action and reap the tax benefits.
The court struck down a federal law that required states to ban gambling on the outcome of sporting events. The Professional and Amateur Sports Protection Act was highly unusual: it did not ban sports gambling nationwide as a matter of federal law, but it said the states were not allowed to permit it. Nevada was grandfathered in when the law was passed in 1992.
New Jersey and then-Gov. 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. The gambling law, Christie said, commandeered the states by forcing them to prohibit sports wagering.
