(b) If the district court denies a certificate of appealability, a party may seek a certificate of appealability from the court of appeals. In the event that a party does not file an application for such a certificate, the court of appeals will construe a party’s filing of a timely notice of appeal as an application to the court of appeals for a certificate of appealability.
(c) An application to the court of appeals for a certificate of appealability may be considered by a single circuit judge. The denial of a certificate of appealability, whether by a single circuit judge or by a panel, may be the subject of a motion for reconsideration but may not be the subject of a petition for panel rehearing or a petition for rehearing en banc.
