MEMORANDUM **

Jason Barnard appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action alleging a Thirteenth Amendment claim. We have jurisdiction under 28 U.S.C, § 1291. We review de novo a sua sponte dismissal for failure to state a claim. Barrett v. Belleque, 544 F.3d 1060, 1061 (9th Cir. 2008). We affirm.

The district court properly dismissed Barnard’s action as frivolous because Barnard’s claims lacked any arguable basis in law or fact. See Neitzke v. Williams, 490 U.S. 319, 325, 109 S.Ct. 1827, 104 L.Ed.2d 338 (1989) (a “frivolous” claim lacks an arguable basis either in law or in fact; the “term ‘frivolous’ ... embraces not only the inarguable legal conclusion, but also the fanciful factual allegation”); .see also Spew-ling v. Hoffman Constr. Co., 864 F.2d 635, 638 (9th Cir. 1988) (court may sua sponte dismiss for failure to state a claim without notice or an opportunity to respond where plaintiff cannot possibly win relief). Moreover, Barnard failed to show that the United States has waived its sovereign immunity from suit. See United States v. Mitchell, 463 U.S. 206, 212, 103 S.Ct. 2961, 77 L.Ed.2d 580 (1983) (“It is axiomatic that the United States may not be sued without its.consent and that the existence *388 of consent is a prerequisite for jurisdiction.”); Jachetta v. United States, 653 F.3d 898, 904 (9th Cir. 2011) (§ 1983 does not waive sovereign immunity).

Barnard’s motion to file a substitute brief, filed on October 23, 2014, is granted. The Clerk shall file the opening brief received October 6,2014.

AFFIRMED.
