The news was somewhat expected, though still disappointing for New Jersey and sports bettors everywhere. New Jersey state Senator Ray Lesniak said this development "does not impact our legal strategy in any way".
The DOJ, along with the NCAA and the four biggest pro North American sports leagues, will be defending the constitutionality of the 1992 Professional and Amateur Sports Protection Act, which is standing in New Jersey's way of legalizing sports betting.
The DOJ was initially given a deadline of Jan. 20, but since that was a Sunday and Monday was a holiday, the deadline became Tuesday according to Griffin Finan, a lawyer in Washington, D.C. who specializes in iGaming and sports law. He gives a brief history of the case here, which will quickly bring you up to speed if you haven't been following to this point.
