ORDER

District judge James Zagel presided over a Title VII case brought by Martha Collier against her then-employer Bankers Life & Casualty Co., which has already been the subject of an appeal before this court. See Collier v. Bankers Life & Cas. Co., et al., 79 Fed.Appx. 213 (7th Cir. 2003) (unpublished order). In January 2004, Collier filed a separate lawsuit against Judge Zagel and unspecified “Judges in the Seventh Circuit Court of Appeals,” complaining about various decisions made in connection with her Title VII case.1 *576Judge Charles Norgle dismissed the lawsuit, citing the principle of absolute judicial immunity. See Mireles v. Waco, 502 U.S. 9, 11-12, 112 S.Ct. 286, 116 L.Ed.2d 9 (1991); Doyle v. Camelot Care Ctrs., Inc., 305 F.3d 603, 622 (7th Cir. 2002). Collier appeals that dismissal, but Judge Norgle was correct: judges are absolutely immune from lawsuits alleging improper or inadequate performance of their judicial functions. See Twisdale v. Snow, 325 F.3d 950, 952 (7th Cir. 2003). The lawsuit and the appeal are both frivolous. We warn Collier that frivolous lawsuits and appeals can result in the imposition of sanctions. See Fed.R.Civ.P. 11; Fed. R.App. P. 38.

AFFIRMED.
