William HilLL, said Monday it expects to launch operations in New Jersey “as soon as responsibly possible” after a U.S. Supreme Court ruling opened the door for states to allow betting on sporting events.

The court sided with a challenge brought by the state of New Jersey, which has waged a six-year battle to allow sports betting within its borders. The Supreme Court agreed that a 1992 federal law which says states can’t “sponsor, operate, advertise, promote, license, or authorize” sports gambling” exceeded the powers of Congress.

“This is a landmark moment for sports betting and for William Hill. Now, all attention shifts to the states, where steps have already been taken to prepare for this day. Legalized sports betting means that consumers and sports leagues will have greater protection, states will benefit from the raising of taxes and there is the potential for over 100,000 jobs to be created,” said Philip Bowcock, chief executive of William Hill, in a statement.

Mr. Bowcock said William Hill is actively working on opportunities in a number of other states in addition to New Jersey.
