Does a federal court have an obligation to resolve a jurisdictional issue that the parties have declined to address?

⁹ We raised this issue sua sponte and gave the parties a chance to submit briefing to address it. Because our inquiry is jurisdictional, we are obligated to resolve the issue regardless of the content of the parties submissions. See Henderson ex rel. Henderson v. Shinseki , 562 U.S. 428, 434, 131 S.Ct. 1197, 179 L.Ed.2d 159 (2011) ("[F]ederal courts have an independent obligation to ensure that they do not exceed the scope of their jurisdiction, and therefore they must raise and decide jurisdictional questions that the parties either overlook or elect not to press.").
