A group of 39 state attorneys general and the Native American tribe whose litigation helped create the framework for tribal gaming are among those urging the Supreme Court to hear New Jersey’s appeal of its lawsuit against Kalshi…

The briefs were filed after New Jersey submitted a petition for certiorari last month, asking the Supreme Court to hear the case. That petition followed the Third Circuit Court of Appeals’ decision to grant Kalshi an injunction that prevents New Jersey from enforcing its sports betting laws against the business.

On Wednesday, a group of attorneys general from 39 states plus the District of Columbia, led by Ohio Attorney General Andrew Wilson, submitted an amicus brief to the Supreme Court, asking it to take on the case and overturn the Third Circuit’s decision.
