Notice of Appeal. Rule 4(b) of the Federal Rules of Appellate Procedure requires a defendant to file a notice of appeal within fourteen days after “(i) the entry of either the judgment or the order being appealed; or (ii) the filing of the government's notice of appeal.” Rule 4(b) is not jurisdictional and thus gives courts discretion to waive filing deadlines for criminal defendants. The government must file a notice of appeal within thirty days “after the later of: (i) the entry of the judgment or order being appealed; or (ii) the filing of a notice of appeal by any defendant.” A district court may extend a party's filing period for up to thirty days upon a showing of “excusable neglect or good cause.”
