Gov. Christie's office said he would pursue an appeal of the 2-1 decision.
"Gov. Christie has said all along this issue will likely be decided by the U.S. Supreme Court, and that's what he believes should happen next," said Colin Reed, his deputy communications director.
"There's no reason [sports betting] should be limited to only a handful of states. It's a fundamental issue of fairness, and Gov. Christie will not give up this fight," Reed said.
Christie signed New Jersey's sports-betting law in January 2012, after a question on the issue passed in a referendum in November 2011. The state wrote regulations, but a federal judge in Trenton blocked the state from implementing them in February by ruling in favor of the NCAA and four major sports leagues.
The NCAA has said that the spread of legalized betting would undermine the integrity of athletic competition.
The case has national implications.
"This was being watched throughout the casino industry nationwide and by political leaders in many other states" where expanded gambling is under consideration, said Joseph S. Weinert, an executive vice president at Spectrum Gaming Group, a consulting firm in Linwood, N.J. "Sports betting would have been a potential avenue for them."
The key for Atlantic City would not be the sports betting itself, which is only marginally profitable.
"The real significance of this is to get people in the door so that they are staying there, eating there, so they are shopping there and going to shows there," said Lloyd D. Levenson, chief executive of Cooper Levenson, an Atlantic City law firm and chairman of its casino law group.
For years, Atlantic City has been losing gamblers to Pennsylvania, New York, and Maryland, as those states legalized or expanded gambling. Through August, Atlantic City casinos won $1.77 billion from gamblers, down 9 percent from the same period last year.
There's no guarantee that the U.S. Supreme Court will accept an appeal, but a lawyer said the case might make the cut.
"In a case of this magnitude, when you have a judge who disagrees with the panel's decision, it certainly may make the Supreme Court more interested in the case," said Christopher L. Soriano, an associate in the Cherry Hill office of Duane Morris L.L.P.
Another possible path to the legalization of sports gambling in New Jersey runs through Congress.
U.S. Reps. Frank LoBiondo (R., N.J.) and Frank Pallone Jr. (D., N.J.) are pushing two bills that would amend the Professional and Amateur Sports Protection Act. One bill would add New Jersey to the list of states allowed to have sports wagering, while the other would open a four-year window during which any state could enact sports-betting legislation.
