ORDER

This is Sylvester Thomas’s fourth lawsuit brought under 42 U.S.C. § 1983 challenging some aspect of his civil commitment as a sexually violent person. See Wis. Stat. § 980; Thomas v. Van Hollen, No. 10-C-50 (E.D.Wisc. Jan. 28, 2010) (dismissing suit challenging constitutionality of Wisconsin’s system of involuntary commitment of sexually violent persons), aff'd, 371 Fed.Appx. 680 (7th Cir. 2010); Thomas v. Van Hollen, No. 10-C-46 (E.D.Wisc. Jan. 28, 2010) (same); Thomas v. McMahon, 09-C-1009, 2009 WL 3711556 (E.D.Wisc. Nov. 2, 2009) (dismissing suit challenging rulings on motions filed in Chapter 980 proceeding and evidence used to have him committed). In his latest challenge, Thomas sued the psychologist who evaluated him in anticipation of the Chapter 980 hearing. Thomas sought damages, alleging that in his evaluation the psychologist falsified data and relied on outdated criteria to assess his dangerousness. The district court dismissed the suit before service, see 28 U.S.C. § 1915(e)(2)(h), reasoning that Thomas’s claims are barred by Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994).

On appeal, Thomas renews his contentions that the psychologist lied in his report. But if this is true, the falsified report calls into question the validity of Thomas’s commitment, which is based on that report. Thomas may not sue for damages under § 1983 unless and until his commitment has been invalidated. Heck, 512 U.S. at 486-87, 114 S.Ct. 2364; see Huftile v. Miccio-Fonseca, 410 F.3d 1136, 1139-40 (9th Cir. 2005). At this point, Thomas’s remedy for errors in the Chapter 980 proceeding lies in his habeas corpus proceeding.

AFFIRMED.
