OJ Simpson attempts to overturn his 2008 armed robbery conviction.
O.J. Simpson will be back in a Las Vegas courtroom Monday to ask for a new trial.
Five years ago Simpson was found guilty of bursting into a room at a Las Vegas Casino Hotel with accomplices and robbing two sports memorabilia dealers.
That conviction was 13 years to the day after Simpson was acquitted of the murders of his former wife, Nicole Brown Simpson and Ronald Goldman.
Now the former football hero will be back before a different judge with claims that he had such bad representation that he deserves a new trial.
He also claims his trial attorney Yale Galanater never told him about a plea offer that he would have taken.
Former Clark County District Attorney David Roger, who prosecuted the case, says that's not true.
"We went back to Galanter and said if OJ is willing to do 30 months in prison we'd have something to talk about," Roger says. "There wasn't a formal offer, we just wanted to get the lay of the land from Yale Galanter. He came back the next day and said OJ will take no more than 12 months."
The judge has agreed to hear evidence and consider 18 of 22 questions cited in the appeal.
Simpson has served four years of his maximum 33 year sentence.
He must serve five more before he's eligible for parole.
By then he would be 70, so without a new trial, it's possible he could spend the rest of his life behind bars.
