CINCINNATI (AP) - A federal appeals court is set to hear an appeal from two attorneys imprisoned after being convicted of bilking their clients out of millions from a settlement involving the diet drug fen-phen.

The U.S. 6th Circuit Court of Appeals in Cincinnati is scheduled to take up the case of 60-year-old William Gallion and 57-year-old Shirley Cunningham Jr., on Tuesday at 1:30 p.m. EST.

Gallion and Cunningham, former owners of champion racehorse Curlin, were convicted in 2009 of illegally keeping $126 million, more than 63 percent of the settlement between their clients and the makers of fen-phen, American Home Products.

A state judge in 2007 awarded $42 million to 431 former clients of the now-disbarred attorneys. A related civil case against class-action guru Stanley Chesley of Cincinnati is pending.
