MEMORANDUM ***
Thomas Dewey Easton appeals pro se from the district courts judgment dismissing his action alleging federal and state law claims arising from the suspension of his drivers license. We have jurisdiction under 28 U.S.C. § 1291. We affirm.
The district court dismissed Eastons action on the basis of res judicata. The only challenge to the district courts application of res judicata that Easton raises in his opening brief is that this court has not yet resolved his previous appeal, No. 19-35699, but on August 12, 2020, this court decided that appeal by affirming the district courts judgment. Because Easton raises no other challenge to the district courts application of res judicata, Easton has waived any such challenge. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009); Acosta-Huerta v. Estelle, 7 F.3d 139, 144 (9th Cir. 1993) (issues not supported by argument in pro se appellants opening brief are waived).
The district court properly substituted the United States as a party for defendant Howell. In order to challenge the Attorney Generals decision regarding the scope of the employment certification, Easton was required to “allege sufficient facts that, taken as true, would establish that [Howells] actions exceeded the scope of [her] employment,” but Easton failed to do so. Saleh v. Bush, 848 F.3d 880, 886, 889 (9th Cir. 2017) (citation and internal quotation marks omitted) (standard of review).
The district court properly denied Eastons motion to remand. The Attorney General certified that Howell was an employee of the Department of Veterans Affairs and was acting within the scope of her employment during the incidents described in Eastons complaint, and “certification is conclusive for purposes of removal, i.e., once certification and removal are effected, exclusive competence to adjudicate the case resides in the federal court, and that court may not remand the suit to the state court.” Osborn v. Haley, 549 U.S. 225, 231, 127 S.Ct. 881, 166 L.Ed.2d 819 (2007); D-Beam Ltd. Pship v. Roller Derby Skates, Inc., 366 F.3d 972, 974 n.2 (9th Cir. 2004) (standard of review).
The district court did not abuse its discretion by dismissing Eastons complaint without leave to amend because amendment would have been futile. See Cervantes v. Countrywide Home Loans, 656 F.3d 1034, 1040-41 (9th Cir. 2011) (setting forth standard of review and explaining that a district court may deny leave to amend if amendment would be futile).
We reject as without merit Eastons contentions that the district court was required to conduct hearings and grant discovery, and that the district court failed to rule on his request for judicial notice.
We do not consider arguments and allegations raised for the first time on appeal. See Padgett, 587 F.3d at 985 n.2.
AFFIRMED.
