The U.S. Supreme Court has refused to take up a challenge to an agreement that gave the Seminole Tribe exclusive rights to handle online sports betting in Florida, dealing a blow to the deal’s opponents. The nation’s highest court on Monday denied a petition from companies that oppose the compact, which promises to rake in hundreds of millions of dollars for the tribe and the state. It is the latest setback for West Flagler Associates and Bonita-Fort Myers Corporation, which operate racetracks and poker rooms in Florida. In March, the Florida Supreme Court also ruled against the companies' challenge.
