Frederick Pitchford appeals the district court’s 1 preservice dismissal of his civil rights action. We conclude that dismissal was proper. See Mireles v. Waco, 502 U.S. 9, 11-12, 112 S.Ct. 286, 116 L.Ed.2d 9 (1991) (per curiam) (judicial immunity); Kurtz v. City of Shrewsbury, 245 F.3d 753, 758 (8th Cir. 2001) (requirements for conspiracy claim under 42 U.S.C. § 1985); Jensen v. Henderson, 315 F.3d 854, 863 (8th Cir. 2002) (42 U.S.C. § 1986 claim depends on existence of valid § 1985 claim). Accordingly, we affirm. See 8th Cir. R. 47B.
