Did the Court of Appeals for the Third Circuit fail to award the Petitioner a new trial as the result of error in the District Court where the Court allowed the government to introduce evidence of Petitioner's prior conviction

QUESTION PRESENTED FOR REVIEW Did the Court of Appeals for the Third Circuit so far depart from the accepted and usual course of judicial proceedings, or sanctioned such a departure by a lower court when it failed to award the Petitioner a new trial as the result of error in the District Court where the Court allowed the government to introduce evidence of Petitioner’s prior conviction as to call for an exercise of this Court’s supervisory power?
