    Jeffrey Scott DURHAM, Petitioner-Appellant, v. Robert A. HOOD, Respondent-Appellee.
    No. 05-1074.
    United States Court of Appeals, Tenth Circuit.
    July 21, 2005.
    
      Jeffrey Scott Durham, United States Penitentiary, ADX, Florence, CO, for Petitioner-Appellant.
    Before KELLY, O’BRIEN, and TYMKOVICH, Circuit Judges.
    
    
      
       After examining the briefs and the appellate record, this three-judge panel has determined unanimously that oral argument would not be of material assistance in the determination of this appeal. See Fed. R.App, P. 34(a); 10th Cir. R. 34.1(G). The cause is therefore ordered submitted without oral argument.
    
   ORDER AND JUDGMENT

TYMKOVICH, Circuit Judge.

Appellant Jeffrey Scott Durham, a federal prisoner appearing pro se, appeals the district court’s denial of his petition for a writ of habeas corpus under 28 U.S.C. § 2241. For the reasons set forth below, we affirm the district court’s order.

Durham is currently in the custody of the United States Bureau of Prisons (BOP) at the United States Penitentiary, Administrative Maximum, at Florence, Colorado. In his § 2241 petition, filed in the United States District for the District of Colorado, Durham challenges the BOP’s use of the Inmate Financial Responsibility Program (IFRP), which requires him to pay court-ordered restitution pursuant to the sentencing judgment of the United States District Court for the Northern District of Florida — the district in which Durham was tried and convicted. Because Durham is proceeding pro se, we construe his petition liberally. See Haines v. Kerner, 404 U.S. 519, 520, 92 S.Ct. 594, 30 L.Ed.2d 652 (1972).

Durham’s petition can be read to make out two distinct claims. First, Durham apparently challenges the delegation of judicial authority by the sentencing court to the BOP. He cites extensively to our decision in United States v. Overholt, 307 F.3d 1231 (10th Cir.2002), which holds that 18 U.S.C. § 3664 prohibits a sentencing court from delegating to the BOP the task of establishing a payment schedule for the payment of court-ordered restitution. Id. at 1255-56. However, as noted by the district court, we lack jurisdiction to entertain a claim of judicial delegation. This is because such a claim implicates the validity of Durham’s sentence, and Durham can only attack the validity of his sentence through a 28 U.S.C. § 2255 petition filed in the district court that sentenced him. See Bradshaw v. Story, 86 F.3d 164, 166-67 (10th Cir.1996) (holding that a petition under § 2241 attacks the execution of a sentence, while a § 2255 petition attacks the validity of a judgment and sentence); see also Matheny v. Morrison, 307 F.3d 709, 711 (8th Cir.2002) (dismissing delegation claim brought under § 2241). Thus, if Durham is to make an improper delegation claim, he must do so through a § 2255 petition filed in the Northern District of Florida.

Second, Durham’s petition can also be read to challenge the IFRP’s constitutionality; namely, that the BOP lacks the constitutional authority to establish payment amounts that Durham must follow in connection with the court-ordered restitution. The essence of this claim is that decisions such as the amount and timing of IFRP payments constitute core judicial functions under Article III, and therefore a district court cannot delegate those functions without violating separation of powers.

The IFRP, set forth in 28 C.F.R. §§ 545.10 and 545.11, requires participating inmates to commit a percentage of their prison employment earnings toward the payment of court-ordered restitution. Its constitutionality has been considered and upheld by other circuits. See McGhee v. Clark, 166 F.3d 884, 886 (7th Cir.1999) (noting that the IFRP “has been uniformly upheld against constitutional attack”); Dorman v. Thornburgh, 955 F.2d 57, 58-59 (D.C.Cir.1992) (holding IFRP does not deprive inmates of constitutional rights to due process); Johnpoll v. Thornburgh, 898 F.2d 849, 851 (2d Cir.1990) (per curiam) (holding BOP did not exceed its authority in establishing IFRP and that the program does not violate due process); see also United States v. Williams, 996 F.2d 231, 234 (10th Cir.1993) (acknowledging constitutionality of the IFRP).

We agree with the other courts that have considered these issues. The BOP does not exceed its authority by setting a payment schedule for inmates such as Durham. As noted by the Second Circuit, the IFRP “serves a valid penological objective of rehabilitation by facilitating repayment of debts,” and “is fully consistent with the Bureau of Prisons’ authorization, under the direction of the Attorney General, to provide for rehabilitation and reformation.” Johnpoll, 898 F.2d at 851. Nor do we believe, on this record, that the district court violated separation of powers principles by improperly delegating Article III functions to the BOP. Durham has simply not shown any indication that the district court delegated any core judicial functions. Accord Montano-Figueroa v. Crabtree, 162 F.3d 548, 550 (9th Cir.1998) (holding IFRP is neither a usurpation of sentencing court’s Article III power nor violation of separation of powers doctrine); Mujahid v. Crabtree, 999 F.Supp. 1398, 1402-04 (D.Or.1998) (to the same effect).

Of course, Durham is free to not participate in the IFRP if he so chooses. Although his refusal to participate is not without consequences, see 28 C.F.R. § 545.11(d), the benefits that can be denied are not constitutionally guaranteed. See, e.g., James v. Quinlan, 866 F.2d 627, 629-30 (3d Cir.1989) (inmates do not possess a liberty or property interest in prison job assignments).

Accordingly, the district court’s order dismissing Durham’s § 2241 petition is AFFIRMED. Durham’s motion to proceed in forma pauperis is GRANTED. 
      
       This order is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. The court generally disfavors the citation of orders; nevertheless, an order may be cited under the terms and conditions of 10th Cir. R. 36.3.
     
      
      . Because this claim attacks the execution of Durham’s sentence, it is properly raised in a § 2241 petition. See Matheny, 307 F.3d at 711-12; Phillips v. Booker, 76 F.Supp.2d 1183, 1192 (D.Kan.1999).
