Maybe I wasnt clear enough. Sullivan filed the papers thru his attorney. I was musing that he appointed this former judge, John Gleason, to challenge the Flynn motions and Gleason apparently did not have the balls to file a petition for hearing en banc himself. So that meant Sullivan had to do it if he wanted a review by the entire court.
See post 20.
As a former judge himself, Gleason, unlike Wilkerson, would know that this was not permitted.
