David Thomas Rhodes appeals the district court’s order dismissing his 28 U.S.C. § 2241 petition as moot. Rhodes’ petition challenges only the length of his prison sentence. But he concedes he is no longer in prison. Although he remains subject to a long term of supervised release, this court cannot issue a judgment on his § 2241 petition that will shorten his supervised release term. Exercising jurisdiction under 28 U.S.C. § 1291, and reviewing de novo,
see Faustin v. City & County of Denver,
I
Rhodes was convicted on drug-related charges in 1993, and sentenced to twenty years’ imprisonment and ten years’ supervised release. He filed this § 2241 peti *933 tion in 2010, challenging the Federal Bureau of Prisons’ calculation of his sentence. After discovering that Rhodes was no longer in prison, the district court ordered him to show cause why his § 2241 petition should not be dismissed as moot. Rhodes conceded that he was no longer incarcerated, but claimed he could still challenge his sentence. He argued that, had his sentence been shorter, he would have started his term of supervised release earlier, and was consequently “suffering from collateral consequences from conviction adequate to meet Article Ill’s injury in fact requirement.” The district court dismissed the petition as moot, concluding that even if Rhodes’ argument were correct, the court had no authority to shorten the length of his supervised release.
II
Federal judicial power is limited by the Constitution to “Cases” and “Controversies,” U.S. Const, art. Ill, § 2, and the case-or-controversy limitation underpins both standing and mootness jurisprudence.
Friends of the Earth v. Laidlaw Envtl. Servs.,
Rhodes has completed his prison sentence. To the extent that he seeks a shorter term of imprisonment, it is obviously no longer possible to provide such relief. But release from prison does not necessarily moot a habeas petition.
See, e.g., Carafas v. LaVallee,
We agree that Rhodes may continue to assert an actual injury so long as he remains subject to supervised release. This is not the problem with his § 2241 petition. The question is not whether the petition, which challenges only the calculation of Rhodes’ prison sentence, asserts a collateral consequence, but whether it asserts a redressable collateral consequence.
A
Whether to grant a motion to terminate a term of supervised release under 18 U.S.C. § 3583(e)(1) is a matter of sentencing court discretion.
See United States v. Lowe,
But Rhodes advances a different argument for relief: Although we cannot directly shorten Rhodes’ term of supervised release, he asks that we declare that the sentence he served was excessive as a matter of law. Such a declaration might bolster his eventual § 3583(e)(1) petition asking the sentencing court to shorten his term of supervised release. As it turns out, our sister circuits are split on whether such an argument defeats mootness.
B
In
Johnson v. Pettiford,
which involved a § 2241 petitioner in the same situation as Rhodes, the Fifth Circuit explained (without further analysis) that “the possibility that the district court may alter [the petitioner’s] period of supervised release pursuant to [§ 3583(e)(1) ], if it determines that he has served excess prison time, prevents [the] petition from being moot.”
An opposite conclusion was reached by the Third Circuit in
Burkey v. Marberry,
In an unpublished decision, the District of Columbia Circuit recently followed
Bur-key. See United States v. Bundy,
C
We agree with the result suggested by the Third and District of Columbia Circuits. “A case is moot if events have so transpired that the decision will neither presently affect the parties’ rights nor have a more-than-speculative chance of affecting them in the future.”
Transwestern Pipeline v. FERC,
Rhodes’ ability to obtain modification under the supervised release statute remains wholly within the discretion of the sentencing court. In making this discretionary determination, a sentencing court considers a variety of factors under § 3553(a).
See
§ 3583(e). If Rhodes did in fact serve too much time in prison, a sentencing court might also place weight on that equitable consideration. But the court could nevertheless conclude, for example, that Rhodes would benefit from additional substance abuse treatment and therefore refuse to terminate his supervised release—even in light of an over-long sentence. In other words, at this point it is entirely speculative whether a declaration from this court stating that Rhodes’ sentence was excessive will aid him in the future.
See United States v. Juvenile Male,
— U.S.-,
Ill
Rhodes can ask for a shorter term of supervised release. But to do so he must file a § 3583(e)(1) petition. This habeas petition, challenging only his sentence, is moot. The district court’s order dismissing Rhodes’ § 2241 petition for that reason is AFFIRMED.
