Is Rule 50(b)’s deadline jurisdictional?

“Repeatedly emphasizing that the classification turns on whether the deadline is in a statute, the Supreme Court has held that the time limits in Civil Rule 23(f), Appellate Rule 4(a)(5)(C), Criminal Rules 33 and 45, and Bankruptcy Rules 4004 and 9006 are not jurisdictional. The Court has not addressed the rule we confront, Civil Rule 50(b). But its reasoning in these cases—that “[i]t is axiomatic that the Federal Rules of Civil Procedure do not create or withdraw federal jurisdiction,”—compels the conclusion that Rule 50(b) is also a claim-processing requirement. We therefore hold that Rule 50 does not impose a jurisdictional deadline.” Escribiano v. Travis County, No. 19-50236 (Jan. 10, 2020).
