Phillip Van Zant appeals the district court’s denial of his pro se habeas petition challenging a parole revocation proceeding. We reverse and remand with instructions to dismiss the petition for lack of subject matter jurisdiction because Van Zant was not “in custody” under 28 U.S.C. § 2241 to challenge the parole revocation at the time of the filing of his petition.
I. BACKGROUND
In 1979, Van Zant entered a plea of nolo contendere to second degree murder and was sentenced to life imprisonment. On August 16, 1983, the Florida Parole Commission (the Commission) released Van Zant on parole. On December 18, 1985, his parole was revoked. On June 3, 1986, Van Zant was released on parole for a second time. His second parole was revoked on September 30, 1987. As a result of this second violation, the Commission enhanced Van Zant’s presumptive parole release date by five years for having two parole revocations and set the date at October 29, 2006. From 1989 to 1991, Van Zant unsuccessfully challenged the second parole revocation in state courts. After exhausting his state remedies, Van Zant filed a federal habeas corpus petition. On July 29, 1992, the district court dismissed the petition as moot because Van Zant had been released on parole for the third time on October 29, 1991. 1 Van Zant’s third parole *327 was revoked on August 19, 1992. On January 12, 1993, the Commission established Van Zant’s next parole date at July 23, 2005, having enhanced it by ten years for three parole revocations. Van Zant is currently incarcerated.
On September 22,1994, Van Zant filed the instant habeas petition reasserting his previous challenges to the second revocation. He alleged that at the preliminary hearing he was denied counsel, denied the right to confront witnesses, prejudiced by the admission of uncharged criminal conduct, and denied the opportunity to present witnesses. He also alleged that his parole revocation violated Florida statutes and that the Commission had abused its discretion. The Commission responded that Van Zant was no longer “in custody” under 28 U.S.C. § 2241 to challenge the second parole revocation because he had been released from the incarceration resulting from the second parole revocation.
The magistrate judge found that Van Zant was “in custody” because the second revocation had been used to enhance his current parole date. The magistrate judge then recommended denying relief, finding Van Zant’s claims meritless. The district court adopted the magistrate’s report, and denied Van Zant’s petition. On appeal, Van Zant repeats the merits of his claims.
II. DISCUSSION
Federal district courts have jurisdiction to entertain habeas petitions only from persons who are “in custody in violation of the Constitution or laws or treaties of the United States.” 28 U.S.C. § 2241(c)(3). A petitioner is not “in custody” to challenge a conviction when the sentence imposed for that conviction has completely expired.
Maleng v. Cook,
The issue is whether Van Zant is incarcerated under a current sentence that has been enhanced by the parole revocation he seeks to expunge. Van Zant asserts that the imposition of a parole date is equivalent to incarceration under a current sentence and his parole date has been enhanced by an extra five years on account of the parole revocation. 3 He seeks relief from this Court to *328 expunge the second parole revocation from his record so that it will not be used to enhance his current parole date.
Initially, we note that the grant of parole is entirely discretionary, and the parole release date is just a presumption, not an effective release date.
See Florida Parole and Probation Comm’n v. Paige,
We hold that the relationship between the challenged parole revocation and Van Zant’s current parole date is too “speculative and remote” for us to find that the parole revocation enhanced Van Zant’s parole date.
Sinclair v. Blackburn,
III. CONCLUSION
We reverse and remand for the district court to dismiss the petition for lack of subject matter jurisdiction.
REVERSED AND REMANDED.
Notes
. It appears that Van Zant did not pursue a timely appeal of his federal habeas petition. On *327 October 14, 1994, the district court entered an "Order Denying Motion for Belated Appeal.”
. This case does not concern the issue of mootness. The issue of jurisdiction under the habeas statute precedes and is separate from the issue of mootness.
Tyars v. Finner,
. We do not decide whether imposition of a parole date is equivalent to incarceration under a current sentence. We note that Van Zant was imprisoned for life and his habeas petition does not challenge that conviction. He challenges the revocation of his second parole in 1987 which resulted in a reinstatement of his life sentence. The sentence of reinstatement expired when he was subsequently paroled for the third time in 1991. The proper time to file a federal habeas petition in this case was after the second parole *328 revocation and before being subsequently paroled. Apparently, Van Zant filed such a petition, but he did not seek review of the district court's denial of the petition. See supra note 1.
