John Stamos can rest easy.
According to the ruling obtained by E! News, federal appeals court in Cincinnati denied a challenge to the indictment brought by attorneys for Allison Coss and Scott Sippola.
"Because the indictment was sufficient, the extortion statute is constitutional, and their sentences were properly imposed, we AFFIRM the defendants' convictions and sentences," read the opinion.
Additionally, the three-judge panel also refused to reduce their time in the Big House after the pair alleged they deserved a more lenient sentence because they accepted responsibility for their actions.
After hearing testimony from Stamos himself, a jury found 25-year-old Coss and 32-year-old Sippola guilty in July 2010 of trying to extort $680,000 from the thespian by threatening to make public some supposedly compromising photos of the TV hunk cavorting with strippers and cocaine at a 2004 party. As it happened, the two never had any such photos, per the feds, and following the highly publicized trial they were handed four years in a federal pen.
A rep for Stamos was unavailable to comment on today's developments.
