This time, his shyster lawyers haven't been able to get him turned loose:

The Nevada Supreme Court isn't going to let O.J. Simpson out of prison while he appeals his conviction in a gunpoint hotel room heist.

A three-judge panel issued orders Friday concluding that Simpson and convicted co-defendant Clarence "C.J." Stewart didn't meet the "heavy burden" required to be allowed to post bail.

The justices noted that a jury found Simpson and Stewart guilty of "serious, nonprobationable, violent offenses" with firearms involved.

They also cited a Clark County District Court judge's finding that the men posed flight risks.

Simpson and Stewart were convicted of kidnapping and robbing two sports memorabilia dealers in September 2007 at a Las Vegas casino-hotel.

Simpson is serving nine to 33 years in prison. Stewart is serving 7 1/2 to 27 years.
