The sports betting legal market dramatically shifted when the U.S. Supreme Court struck down the Professional and Amateur Sports Protection Act (PASPA) as unconstitutional commandeering under the 10th amendment. PASPA prohibited state and local legislatures from enacting laws that would favor sports betting. But the U.S. Supreme Court ruled that PASPA was unconstitutional because it “dictates what a state legislature may and may not do.” As a result, PASPA is no longer the primary impediment to legalized sports gambling.
