O.J. Simpson's convicted co-defendant got a fair trial and wasn't a victim of "spillover prejudice" as he alleges in his appeal, a prosecutor told the Nevada Supreme Court on Friday.

"A defendant 'is not entitled to a perfect trial, but only a fair trial,'" wrote Clark County District Attorney David Roger, citing state and federal case law supporting his position that Clarence "C.J." Stewart should remain in prison for his role in a September 2007 armed hotel room heist.

Stewart's lawyer, Brent Bryson, did not immediately respond to a message seeking comment.

Bryson still has a chance to answer the district attorney's 46-page response to Stewart's initial request for the court to overturn Stewart's conviction.

The former Simpson golfing buddy claims he should have been tried separately from the former NFL football star, whose acquittal in the 1994 slayings of his ex-wife, Nicole Brown Simpson, and her friend, Ron Goldman, in Los Angeles was dubbed the "trial of the century."

Stewart also maintains that evidence was improperly used against him, and that the jury foreman hid a bias toward Simpson until after the pair were convicted and sentenced.
