Hopes for legal sports betting in the United States got a boost on Monday as New Jersey argued its case before the US Supreme Court.

Legal sports betting supporters are feeling good about the reactions of a majority of the Supreme Court justices after hearing arguments for and against overturning the federal Professional and Amateur Sports Protection Act (PASPA), which limits single-game sports betting to the state of Nevada.

In case you’ve been re-enacting the movie Castaway for the past few years, Monday’s hearing considered New Jersey’s multi-year quest to overturn PASPA and permit sports betting at Atlantic City casinos and state racetracks. The state lost numerous lower-court rulings before the Supremes agreed in October to hear their appeal.

Opposing New Jersey are the US Department of Justice, the White House, the four major pro sports leagues and the NCAA. However, some of these leagues – most notably, the National Basketball Association and Major League Baseball – have since softened their original anti-betting stance, but still oppose New Jersey’s appeal due to their desire to see Congress impose a nationwide betting regulatory environment.
