I listened to Levin last night on the Sirius. He had a 15 minute segment on Judge Sullivan.
Now, I am not a Philadelphia lawyer but Levin is and he is sharp as a tack. He said that it is not legal to file Amicus briefs in a criminal case. He said this is widely accepted case law. He called Judge Sullivan incompetent and stupid.

Levin didn't say it but I will, this guy is an Affirmative Action judge. Probably got in to law school due to affirmative action, in the first place. His law school grades were probably not too good but the professors gave him a pass.
