LAS VEGAS (KTLA) -- A Nevada judge agreed Friday to reopen the armed robbery and kidnapping case against O.J. Simpson to determine if the former football star should get a new trial.

Clark County District Court Judge Linda Marie Bell agreed to hear evidence and to consider 18 of 22 questions cited in an appeal by Simpson lawyer Patricia Palm.

Simpson, 65, is seeking release from state prison, where he is serving nine to 33 years.

He was convicted in 2008 after authorities said he led five men, including two with guns, in a September 2007 confrontation with two sports memorabilia dealers and a middleman in a cramped room at a Las Vegas casino-hotel.

Simpson trial prosecutor Chris Owens protested that Palm was rehashing issues long settled by Simpson's conviction, which was upheld by the Nevada Supreme Court.

But Palm said Simpson wants a chance to show that his former attorney Yale Galanter had previous knowledge of the plan to retrieve items from the memorabilia dealers that Simpson said were stolen from him after his 1995 acquittal in the Los Angeles slayings of his ex-wife, Nicole Brown Simpson, and her friend, Ronald Goldman.

Galanter, a Miami lawyer who represented Simpson in other cases before the arrest in Las Vegas, denied during trial that he had anything to do with the ill-fated Las Vegas caper.

"Judge, I tell you ... I wasn't there," Galanter said at the time. "I had nothing to do with it."

Simpson says Galanter advised him that the plan to confront the two memorabilia dealers was legally permissible as long as no one trespassed on private property and no physical force was used.

Simpson wanted to testify at trial, but "Galanter advised Simpson that he should not testify because the state could not prove its case," Palm's appeal says.

Simpson also says he never was advised that the Clark County district attorney offered a pretrial deal that could have gotten Simpson two to five years in prison for pleading guilty to robbery.

Palm says Simpson would have taken the offer.
