Darrell J. Harper filed a civil complaint for damages against Jeff Beck, a previous employer, alleging that he was dismissed from his employment on account of his race. Harper alleged claims of “racial profiling,” civil rights violations, corruption, and conspiracy, among other claims. The district court dismissed Harper’s complaint because it violated an injunction entered by that court on December 23, 2002. Harper has filed a motion in this court seeking leave to proceed in forma pauperis (IFP) on appeal.

Because Harper does not address the reason for the district court’s dismissal of his complaint, he has failed to establish a nonfrivolous ground for appeal. See Carson v. Polley, 689 F.2d 562, 586 (5th Cir. 1982); 28 U.S.C. § 1915(a)(3). His IFP motion is DENIED. As the appeal contains no nonfrivolous issues, it is DISMISSED. Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983); 5th Cir. R. 42.2.

We previously cautioned Harper that the filing or prosecution of frivolous appeals would subject him to sanctions. Harper v. City of Houston, 134 Fed.Appx. 736, No. 04-20787 (5th Cir. 2005) (unpublished). That appeal, too, involved the district court’s dismissal for failure to comply with the December 23, 2002, injunction. Because this appeal was briefed prior to our warning, we decline to sanction Harper at this time. However, we reiterate our warning. Harper should review all pending appeals to ensure that they are not frivolous.

MOTION DENIED; APPEAL DISMISSED; SANCTION WARNING ISSUED.
