                  Defendant-Appellee.

                    Appeal from the United States District Court
                       for the Central District of California
                     George H. King, District Judge, Presiding

                             Submitted April 11, 2017**

Before:       GOULD, CLIFTON, and HURWITZ, Circuit Judges.

        Norman Douglas Diamond appeals pro se from the district court’s judgment

dismissing his damages action under 26 U.S.C. § 7433 arising from various

interactions with defendant involving his federal income taxes. We have

jurisdiction under 28 U.S.C. § 1291. We review de novo a dismissal for lack of

subject matter jurisdiction. Harger v. Dep’t of Labor, 569 F.3d 898, 903 (9th Cir.

2009). We affirm.

      The district court properly dismissed Diamond’s action without prejudice for

lack of subject matter jurisdiction because Diamond failed to show his claims fell

within a waiver of sovereign immunity. See Holloman v. Watt, 708 F.2d 1399,

1401 (9th Cir. 1983) (waiver of sovereign immunity “must be unequivocally

expressed,” and “[t]he party who sues the United States bears the burden of

pointing to such an unequivocal waiver of immunity” (citation and internal

quotation marks omitted)); Miller v. United States, 66 F.3d 220, 222-23 (9th Cir.

1995) (waiver of sovereign immunity under § 7433 permitting taxpayers to sue for

misconduct in collection of taxes does not extend to improper determination or

assessment of taxpayer’s liabilities); see also Shwarz v. United States, 234 F.3d

428, 433 (9th Cir. 2000) (“Section 7433 creates a private right of action only for

tax collection activity that violates some provision of the Revenue Code or the

regulations promulgated thereunder.”).

      We reject as meritless Diamond’s contentions that he was improperly denied

discovery and injunctive relief.

      We do not consider matters not specifically and distinctly raised and argued

                                          2                                   15-56100
in the opening brief, or arguments, allegations, or evidence raised for the first time

on appeal. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009); Kirshner

v. Uniden Corp. of Am., 842 F.2d 1074, 1077 (9th Cir. 1988).

      Diamond’s motions for leave to file supplemental briefs (Docket Entry Nos.

39, 41) are granted. The Clerk shall file the supplemental briefs (Docket Entry

Nos. 40, 42).

      All other pending motions and requests (Docket Entry Nos. 2, 6) are denied.

      AFFIRMED.
