"We have developed two separate, but equally effective, pathways toward the same goal of bringing sports gaming and the economic benefits it yields to the State of New Jersey. The New Jersey Betting and Equal Treatment Act of 2012 (NJ BET Act), H.R. 3081, provides New Jersey with an exemption to the federal prohibition [in PASPA]. It allows state law in New Jersey to determine how sports betting will be regulated within the state. The Sports Gaming Opportunity Act of 2012, H.R. 3797, opens a window in which states can enact alaw providing for sports gambling within their state until January 1, 2016,after which the federal prohibition [in PASPA] against states allowing sportsgambling would go back into place."
