NEWARK - A federal appeals court has dealt another blow to New Jersey's efforts to get legalized sports gambling in the state.

In a decision released Tuesday, the 3rd Circuit Court of Appeals in Philadelphia upheld a judge's ruling that New Jersey's law allowing sports betting conflicts with federal law and shouldn't be implemented.

Last spring, a federal judge in Trenton rejected New Jersey's constitutional challenge to the 1992 Professional and Amateur Sports Protection Act. The law prohibits legal sports gambling in all but Nevada and three other states.

Gov. Chris Christie and lawmakers pushed for the legalization of sports gambling as a way to revive New Jersey's lagging casino industry. The NFL, NBA, NHL, Major League Baseball and the NCAA sued the state last year.
