¶1 James Gregory Lynn, Texas prisoner # 636695, moves for leave to proceed in forma pauperis (IFP) to appeal the district court’s dismissal of his civil rights complaint, filed pursuant to 42 U.S.C. § 1983, as frivolous and for failure to state a claim pursuant to 28 U.S.C. § 1915(e)(2)(B)® and (ii). Lynn’s motion is a challenge to the district court’s certification that his appeal is not taken in good faith. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir.1997). As an initial matter, Lynn has abandoned his claim against Cockrell by failing to brief it adequately. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir.1993) (arguments not briefed on appeal are deemed abandoned).
¶2 Lynn avers that Hassel, Lawson, Boy-kin, and Alderman filed and prosecuted false disciplinary cases against him in retaliation for his having filed a prior lawsuit against them. Because an inmate is not required to demonstrate a favorable outcome of a disciplinary case if he is alleging a retaliatory motive, the district court abused its discretion in determining that the retaliation claims against Hassel, Lawson, Boykin, and Alderman were barred by Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994). See Woods v. Smith, 60 F.3d 1161, 1164-66 (5th Cir.1995). Thus, the district court erred in certifying that Lynn was not entitled to proceed IFP on appeal. Therefore, Lynn’s motion to proceed IFP on appeal is GRANTED.
¶3 However, the dismissal of the retaliation claims against Hassel, Lawson, Boykin, and Alderman is AFFIRMED on the basis that Lynn failed to allege facts to support an arguable claim of retaliation. See Hanchey v. Energas Co., 925 F.2d 96, 97 (5th Cir.1990); Woods, 60 F.3d at 1164-66.
¶4 IFP GRANTED; AFFIRMED.
