Wai Leung Chu, federal prisoner # 20645-122, seeks to proceed in forma pauperis (IFP) on appeal from the denial of his motion to produce. In his motion, Chu contended that because he was “a person held in custody for violating probation or supervised release,” Fed.R.Crim.P. 32.1(a)(1) required that he be brought before a magistrate judge for an initial appearance hearing.

Chu’s IFP motion is construed as a challenge to the district court’s determination that the appeal is not taken in good faith. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir. 1997). Our inquiry into whether the appeal is taken in good faith “is limited to whether the appeal involves ‘legal points arguable on their merits (and therefore not frivolous).’ ” Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983) (citation omitted). If the appeal is frivolous, we may dismiss it sua sponte under 5th Cir. R. 42.2. See Baugh, 117 F.3d at 202 n. 24.

Rule 32.1(a)(1) provides that “[a] person held in custody for violating probation or supervised release must be taken without unnecessary delay before a magistrate judge.” Chu was not entitled to a Rule 32.1 initial appearance hearing because Chu is not in federal custody because he violated the terms of his supervised release. See Rule 32.1(a)(1). Rather, he is in federal custody pursuant to his federal convictions for smuggling and trafficking. The plain language of Rule 32.1(a)(1) requires that the person be “in custody for violating probation or supervised release.”

Chu has not demonstrated that he will raise a nonfrivolous issue on appeal. See Howard, 707 F.2d at 219-20. Accordingly, Chu’s motion to proceed IFP is denied. See Baugh, 117 F.3d at 202 n. 24. Because his appeal is frivolous, see Howard, 707 F.2d at 219-20, the appeal is dismissed. See 5th Cir. R. 42.2.

IFP DENIED; APPEAL DISMISSED.
