The full 10th U.S. Circuit Court of Appeals will hear arguments Thursday as judges review a decision overturning Joe Nacchio's April 2007 conviction.

Prosecutors argued he sold $52 million worth of stock when he knew Denver-based Qwest Communications International Inc. was at risk while other investors did not.

In March, a three-judge panel of the appeals court ruled that the trial judge improperly barred testimony from a defense witness. Prosecutors sought a review by the full appeals court, which granted the request.

Still pending is a civil lawsuit the Securities and Exchange Commission filed against former Qwest executives, including Nacchio.
