Southern District U.S. Attorney Preet Bharara has lost his bid to reinstate insider trading convictions that were vacated last year by the U.S. Court of Appeals for the Second Circuit.

The circuit on Friday issued an order denying rehearing en banc and by the original panel that tossed the convictions in December while restricting the scope of criminal insider trading liability in a way that Bharara said has handcuffed law enforcement.
