James L. and Ronald Gantt noted this appeal outside the thirty-day appeal period established by Fed. R. App. P. 4(a)(1), and failed to move for an extension of the appeal period within the additional thirty-day period provided by Fed. R. App. P. 4(a)(5). The time periods established by Fed. R. App. P. 4 are "mandatory and jurisdictional." Browder v. Director, Dep't of Corrections, 434 U.S. 257, 264 (1978) (quoting United States v. Robinson, 361 U.S. 220, 229 (1960)). Appellants' failure to note a timely appeal or obtain an extension of the appeal period deprives this Court of jurisdiction to consider this case. We therefore dismiss the appeal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the Court and argument would not aid the decisional process.
