The US Supreme Court has voted by a margin of 7-2 to overturn the prohibition of sports betting in the US under the Professional and Amateur Sports Protection Act (PASPA) in a ruling issued on 14 May 2018.
The Supreme Court’s ruling can be read here:
In summary the judges decided:
The legalization of sports gambling is a controversial subject. Supporters argue that legalization will produce revenue for the States and critically weaken illegal sports betting operations, which are often run by organized crime. Opponents contend that legalizing sports gambling will hook the young on gambling, encourage people of modest means to squander their savings and earnings, and corrupt professional and college sports. The legalization of sports gambling requires an important policy choice, but the choice is not ours to make.
Congress can regulate sports gambling directly, but if it elects not to do so, each State is free to act on its own. Our job is to interpret the law Congress has enacted and decide whether it is consistent with the Constitution. PASPA is not. PASPA “regulate[s] state governments’ regulation” of their citizens, New York, 505 U. S., at 166. The Constitution gives Congress no such power. The judgment of the Third Circuit is reversed. It is so ordered.
