Notice and appeal deadlines

1. Whether due process permits a federal court of appeals to enforce a twenty-one-day deadline for reconsideration of a certificate-of-appealability denial when the Clerk received and file-stamped a pro se litigant’s change-of-address notice before the denial issued, but the court mailed the dispositive order to the superseded address and the litigant therefore received no timely notice of the order or the deadline. 2. Whether a federal court of appeals may refuse all corrective relief, without addressing the documented notice failure, where the court’s own rules authorize extensions of court-rule deadlines for good cause, subject to Federal Rule of Appellate Procedure 26(b), and authorize recall of a mandate to prevent injustice.
