If New Jersey successfully wins its sports betting case, numerous states across the country that are interested in legalizing such markets might want to extend their thanks to the Garden State.

Financial billing records provided by the New Jersey Division of Law to the Press of Atlantic City shows that law firms representing the state have charged nearly $8.6 million.

Gibson Dunn & Crutcher and Gibbons PC have respectively billed $7 million and $1,577,000 between 2012 through 2017 for making New Jersey’s argument against the Professional and Amateur Sports Protection Act (PASPA) of 1992. The two law firms are associated with Ted Olson, the former US solicitor general who argued against PASPA before the Supreme Court in December.

The $8.57 million total is being footed by the New Jersey Division of Gaming Enforcement and Racing Commission. Those agencies are predominantly funded through taxes and fees generated by Atlantic City casinos.

Jersey lawmakers are betting on sports gambling to provide an economic boost to Atlantic City.

Should the Supreme Court rule that PASPA indeed violates anti-commandeering interpretations of the Tenth Amendment, as Olson and the state contend, a study by Oxford Economics estimates that New Jersey horse racetracks and Atlantic City casinos could generate over $173 million in annual tax revenue.

But lawsuits brought by the NCAA and Big Four (NFL, MLB, NBA, NHL) against New Jersey have halted sports betting in the state, and over the last several years, there’s seemed to be an easing of public opposition to the activity. League commissioners, most specifically the NBA’s Adam Silver, have additionally called for regulation.

The American Gaming Association estimates that $150 billion is bet illegally in the US each year. The lobbying firm believes a regulated industry would better protect both consumers and the sports leagues, and would only increase engagement and interest in the NCAA and Big Four.
