Opinion of the Court
the relief he seeks, then the right course on appeal is to take jurisdiction over the case, explain why that is so, and affirm the BIA's decision not to reopen. The jurisdictional question (whether the court has power to decide if tolling is proper) is of course distinct from the merits question (whether tolling is proper). See Steel Co. v. Citizens for Better Environment, 523 U. S. 83, 89 (1998) (“[T]he absence of a valid . . . cause of action does not implicate subject-matter jurisdiction”). The Fifth Circuit thus retains jurisdiction even if Mata's appeal lacks merit. And when a federal court has jurisdiction, it also has a “virtually unflagging obligation . . . to exercise” that authority. Colorado River Water Conservation Dist. v. United States, 424 U. S. 800, 817 (1976). Accordingly, the Court of Appeals should have asserted jurisdiction over Mata's appeal and addressed the equitable tolling question.
Contrary to amicus's view, the practice of recharacterizing pleadings so as to offer the possibility of relief cannot justify the Court of Appeals' alternative approach. True enough (and a good thing too) that courts sometimes construe one kind of filing as another: If a litigant misbrands a motion, but could get relief under a different label, a court will often make the requisite change. See, e. g., 12 J. Moore, Moore's Federal Practice § 59.11[4] (3d ed. 2015) (explaining how courts treat untimely Rule 59 motions as Rule 60 motions
precludes equitable tolling: It is hard to come up with any other reason why the court construes every argument for tolling as one for sua sponte relief. See Brief for Amicus Curiae by Invitation of the Court 2, 10, 14, n. 2. But the Fifth Circuit has stated that position in only a single sentence in a single unpublished opinion, which (according to the Circuit) has no precedential force. See Lin v. Mukasey, 286 Fed. Appx. 148, 150 (2008) (per curiam); Rule 47.5.4 (2015). And another unpublished decision cuts in the opposite direction, “hold[ing] that the doctrine of equitable tolling applies” when exceptional circumstances excuse an alien's failure to meet the 90-day reopening deadline. Torabi v. Gonzales, 165 Fed. Appx. 326, 331 (CA5 2006) (per curiam). So, in the end, it is hard to say.
