subject-matter jurisdiction, but because district courts must observe the clear limits of the Rules of Criminal Procedure when they are properly invoked. This does not mean that limits like those in Rule 33 are not forfeitable when they are not properly invoked. Despite its narrow and unremarkable holding, Robinson has created some confusion because of its observation that "courts have uniformly held that the taking of an appeal within the prescribed time is mandatory and jurisdictional." Id., at 229 (emphasis added). Indeed, we used the phrase "mandatory and jurisdictional" four times in the opinion. And subsequent opinions have repeated this phrase, attributing it directly or indirectly to Robinson. See, e.g., Hohn v. United States, 524 U. S. 236, 247 (1998); Budinich v. Becton Dickinson & Co., 486 U. S. 196, 203 (1988); Griggs v. Provident Consumer Discount Co., 459 U. S. 56, 61 (1982) (per curiam); Browder v. Director, Dept. of Corrections of Ill., 434 U. S. 257, 264, 271–272 (1978). But see Houston v. Lack, 487 U. S. 266, 269 (1988) (reversing an order dismissing an appeal as jurisdictionally out of time when " "[n]either the District Court nor respondent suggested that the notice of appeal might be untimely"); Thompson v. INS, 375 U. S. 384, 386 (1964) (per curiam) (permitting appeal, when petitioner conceded that post-trial motions were served late, in part because petitioner "relied on the Government's failure to raise a claim of untimeliness when the motions were filed").
As we recognized in Kontrick, courts "have more than occasionally used the term 'jurisdictional' to describe emphatic time prescriptions in rules of court." 540 U. S., at 454. See also ibid. (citing Robinson as an example of when we have been "less than meticulous" in our use of the word "jurisdictional"). The resulting imprecision has obscured the central point of the Robinson case—that when the Government objected to a filing untimely under Rule 37, the court's duty to dismiss the appeal was mandatory.
