ing class-action certification.” Federal Rule of Appellate Procedure 5(a)(2) likewise says that a petition for permission to appeal “must be filed within the time specified.” To be sure, the simple fact that a deadline is phrased in an unqualified manner does not necessarily establish that tolling is unavailable. See Fed. Rule App. Proc. 2 (allowing suspension of other Rules for “good cause”); Fed. Rule App. Proc. 26(b) (similar); Fed. Rule Crim. Proc. 45(b) (similar); Fed. Rule Civ. Proc. 6(b) (similar). Here, however, the Federal Rules of Appellate Procedure single out Civil Rule 23(f) for inflexible treatment. While Appellate Rule 2 authorizes a court of appeals for good cause to “suspend any provision of these rules in a particular case,” it does so with a conspicuous caveat: “except as otherwise provided in Rule 26(b).” Appellate Rule 26(b), which generally authorizes extensions of time, in turn includes this express carveout: A court of appeals “may not extend the time to file… a petition for permission to appeal.” Fed. Rule App. Proc. 26(b)(1). In other words, Appellate Rule 26(b) says that the deadline for the precise type of filing at issue here may not be extended. The Rules thus express a clear intent to compel rigorous enforcement of Rule 23(f)’s deadline, even where good cause for equitable tolling might otherwise exist.
Precedent confirms this understanding. Carlisle, 517 U. S. 416, and Robinson, 361 U. S. 220, both centered on Federal Rule of Criminal Procedure 45(b), an extension-of-time provision that parallels Appellate Rule 26(b). Carlisle addressed Rule 45(b)’s interaction with the time limit in Criminal Rule 29 for filing a postverdict motion for judgment of acquittal. See 517 U. S., at 419–423. Rule 45(b), as it was then written, made clear that “ ‘the court may not extend the time for taking any action’ ” under Rule 29, “ ‘except to the extent and under the conditions’ ” stated therein. Id., at 421. Because the Court found the text’s purpose to foreclose acceptance of untimely motions
