Deposed Los Angeles Clippers owner Donald Sterling has asked an appellate court to block the $2 billion sale of the team to former Microsoft CEO Steve Ballmer.
Lawyers for Sterling asked the Second District Court of Appeals on Friday to stay a probate judge's ruling that cleared the way for the sale.
They say the judge prematurely finalized his ruling so the sale can be completed without a chance to appeal.
It was unclear if the appeal would have any effect since the judge barred any delays pending appeal. The sale could conceivably go forward while the appeal makes its way through the courts.
Sterling's estranged wife, Shelly Sterling, negotiated the record sale after the NBA banned the 80-year-old billionaire for making offensive remarks about blacks.
