New Jersey’s quest for legal sports betting has taken a hit after the White House’s top legal eagle urged the US Supreme Court not to hear the case.

On Wednesday, the office of Acting Solicitor General Jeffrey Wall filed a brief with the Supreme Court urging it not to hear New Jersey’s appeal of lower court rulings preventing the state from authorizing legal sports betting within its borders.

In January, the Court requested the Solicitor General’s opinion on New Jersey’s latest sports betting legislation, which sought to undo the federal PASPA sports betting prohibition by selectively authorizing the activity at state racetracks and Atlantic City casinos.

New Jersey’s legal argument was based on its view that PASPA is unconstitutional due to its violation of the US Constitution’s anti-commandeering clause, which prohibits the federal government from requiring states to enact or enforce federal regulations.
