Task: Wrong Candidate Generation
Input (English): has sixty days after the judgment to file a notice of appeal. Fed. R.App. P. 4(a)(1)(B). Although the parties no longer contest the timeliness of this appeal, the timely filing of an appeal is “mandatory and jurisdictional.” Acevedo-Villalobos v.

(noting that court “lack[s] jurisdiction over late appeals”). The United States, its officer, or agency is a “party” to a case not only where it is a named party to the appeal, see In re Lloyd, Carr, & Co., 617 F.2d 882, 884 n. 1 (1st Cir.1980), but also where it has actively participated in the proceedings, see id.; cf.

Output (English): holding that defendant did not waive special appearance
