Sports betting on football, basketball, baseball and other sports got the go ahead on Monday when the Supreme Court struck down a federal law that bars sports gambling in most states.

According to the AP in the Washington Post, the Supreme Court ruled 6-3 to strike down the Professional and Amateur Sports Protection Act. The law had barred state-authorized sports gambling with a few exceptions.  The challenge was brought by the state of New Jersey, with more than a dozen states supporting the challenge. New Jersey says it can be ready to offer sports betting at its racetracks and casinos within weeks.  More than 30 other states are expected to follow their lead.
