2 POWER DENSITY SOLUTIONS LLC v. US

To be timely, a party must file an appeal within 60 days of the final judgment or order being appealed from the Court of Federal Claims. See 28 U.S.C. §§ 2107, 2522; Fed. R. App. P. 4(a)(1)(B); Fed Cir. R. 1(a)(1)(C). This time limit is “a jurisdictional requirement” and “not subject to equita- ble tolling.” Marandola v. United States, 518 F.3d 913, 914 (Fed. Cir. 2008) (citation omitted). Here, the notice of ap- peal was due no later than May 22, 2023. Fed. R. App. P. 26(a)(1)(C). Because the notice of appeal was not received within that time, we lack jurisdiction and must dismiss. Accordingly, IT IS ORDERED THAT: (1) The motion is granted. The appeal is dismissed. (2) The parties shall bear their own costs. FOR THE COURT
