Does the latest appeal by former Enron CEO Jeffrey Skilling to overturn his May 2006 conviction stand a chance? It depends on who you ask, but the proceedings scheduled for today in New Orleans before a three-judge panel in the 5th U.S. Circuit Court of Appeals are sure to be lively. The big question to be argued: Did prosecutors mishandle key evidence before Skilling’s trial?

Last month Skilling’s legal team, led by O’Melveny & Myers’ Daniel Petrocelli, filed a supplemental appeal accusing prosecutors of failing to disclose more than 400 pages of FBI interview notes. The notes allegedly contain contradictory statements from former Enron CFO — and government witness — Andrew Fastow.
