I. INTRODUCTION
David Meyers appeals the revocation of his supervised release and resulting imprisonment on numerous grounds. The government contends that Meyers’ completion of his term of imprisonment resulting from the revocation order renders this appeal moot. This court concludes that Meyers’ appeal is indeed moot, thus depriving us of jurisdiction to address the merits of his claims.
II. BACKGROUND
On October 5, 1995, in the district court for the District of Wyoming, Meyers was convicted of conspiracy to possess with intent to distribute and distribution of marijuana, as well as aiding and abetting possession with intent to distribute marijuana. He received a sentence of thirty-three months imprisonment followed by three years of supervised release. This court subsequently affirmed his conviction and sentence.
See United States v. Meyers,
Three months after Meyers’ release from prison, a counselor at Border Area Mental Health Service, Inc. of New Mexico (BAMH) collected from Meyers a urine sample, which tested positive for THC, the active ingredient in marijuana. Meyers later informed Probation Officer James Barela that he would no longer cooperate with BAMH. As a result of these occurrences, on July 29, 1998, Probation Officer John Olive petitioned the district court for the District of Wyoming for revocation of Meyers’ supervised release. The petition alleged violations of the following three conditions of Meyers’ supervised release: (1) refraining from the purchase, possession, use, distribution or administration of narcotics, controlled substances, or related paraphernalia except as prescribed by a physician; (2) refraining from the use or possession of controlled substances unless prescribed by a medical practitioner licensed in the United States; and (3) participating in drug and alcohol treatment as directed by the U.S. Probation Office.
Identity and detention hearings were then held in the district court for the District of New Mexico in early August of 1998. The district court detained Meyers for commitment to the District of Wyoming. After Meyers was transported to Wyoming, on September 25, 1998 the district court for the District of Wyoming held a joint preliminary and revocation hearing, at which Meyers represented himself, though appointed counsel was present. The district court found the petition true, revoked Meyers’ release, and sentenced him to nine months imprisonment.
Meyers then appealed the district court’s revocation order, asserting the following five grounds for reversal: 1 (1) the *718 district court erred by allowing Meyers to represent himself at the revocation hearing without determining whether his waiver of counsel was knowing and intelligent; (2) the district court erred by failing to provide a prompt preliminary hearing; (3) the district court erred by denying Meyers an opportunity to examine two adverse witnesses at the revocation hearing; (4) there was insufficient evidence presented at the revocation hearing to support the district court’s finding that Meyers violated terms of his release; and (5) the government waived its right to revoke Meyers’ release because it unreasonably delayed seeking revocation after the alleged violation. In May of 1999, however, while this appeal was pending, Meyers completed the term of imprisonment imposed as a result of the revocation. He is now out of prison, under no further terms of probation or supervised release.
III. DISCUSSION
Before a court addresses the merits of an appeal, it must first determine whether in fact it has jurisdiction over that appeal. Article III of the United States Constitution only extends federal judicial power to eases or controversies. U.S. Const. Art. Ill, § 2, cl. 1. “This case-or-controversy requirement subsists through all stages of federal judicial proceedings, trial and appellate.”
Lewis v. Continental Bank Corp.,
When an incarcerated criminal defendant appeals his conviction, the ongoing incarceration constitutes an injury from which the defendant seeks relief in satisfaction of Article III.
See Spencer v. Kemna,
In
Spencer,
however, the Court declined to extend this presumption of collateral consequences to challenges of parole termination.
See Spencer,
523 U.S. at-,
The
Spencer
court went on to determine that the consequences which the defendant attributed to his parole revocation were insufficient to satisfy Article III.
See id.
at ---,
Less than a year after
Spencer,
this court decided
United States v. Dominguez-Camona,
The only collateral consequence which Meyers advances to counter the government’s mootness claim is the possibility that the sentence he received for the supervised release violation could increase his criminal history score in future sentencing proceedings. Under the guidelines, two points are added to a defendant’s criminal history calculation if the defendant committed the federal crime at issue within two years of release from imprisonment on a sentence of at least sixty days. See U.S.S.G. § 4Al.l(e). In addition, revocation of supervised release may affect the date of release for purposes of section 4Al.l(e). See id. § 4A1.2(k)(2)(A). Therefore, due to the revocation and resulting sentence imposed *720 upon Meyers, his criminal history score will increase by two points should he commit a federal crime within two years of May of 1999 when he completed his revocation sentence; absent the revocation, however, his criminal history calculation would increase by two points only if he commits a federal crime within two years of July 29, 1997, the date of his release from the initial sentence. In short, the revocation of Meyers’ supervised release status and resulting sentence lengthened the amount of time in which he is subject to a potential additional penalty imposed by the guidelines.
Although
Spencer
squarely rejected as too speculative the precise argument for collateral consequences now made by Meyers, the two relevant cases from this court which postdated
Spencer
— •
Dominguez-Carmona
and
Soto-Holguin
— are premised on the very reasoning of Meyers’ argument.
See Spencer,
523 U.S. at---,
The government, however, suggests a means by which this panel can distinguish Dominguez-Carmona and Soto-Holguin from the instant case and thus still conclude, consistent with those cases, that Meyers’ appeal is moot. Specifically, the government asserts that the presumption of collateral consequences established by the Supreme Court attaches to appeals of sentences imposed following an initial conviction, the posture of both DominguezCarmona and Soto-Holguin, but not to challenges of a supervised release revocation and resulting sentence, as in the instant appeal. Thus, the government argues the applicability of this presumption to Dominguez-Carmona and Soto-Holguin but not to Meyers’ appeal moves this case out from under the control of those two cases and squarely within the precedent of Spencer.
Although
Dominguez-Carmona
and
Soto-Holguin
do differ factually and procedurally from Meyers’ appeal, the differences do not present a principled means of distinction. First, whether the presumption of collateral consequences does in fact still apply when a party challenges the sentence imposed following the initial conviction, but not the underlying conviction itself, remains an open question in light of
Spencer. See United States v. Mercurris,
One panel, however, may overrule a point of law established by a prior panel after obtaining authorization from all active judges on the court.
See, e.g., Murphy v. Klein Tools, Inc.,
Indeed, such a holding brings this circuit in line not only with Supreme Court precedent but with every other circuit but one that has considered the issue since

*723 IV. CONCLUSION
Meyers has completed the term of imprisonment resulting from the revocation of his supervised release status and has failed to demonstrate sufficient collateral consequences flowing from the revocation and resulting sentence to defeat the government’s mootness claim. This court therefore lacks jurisdiction to entertain the merits of his appeal, which is hereby DISMISSED.
Notes
. In addition to these errors alleged in Meyers' counsel’s brief, Meyers himself raised several more arguments in a pro se brief which he also filed. This court construed that brief *718 as a motion for permission to file a supplemental brief. In light of our conclusion that this appeal is moot, we deny Meyers' motion to file a supplemental brief.
. The only distinction between
Spencer
and the instant case is that
Spencer
involved a challenge to a revocation of parole, whereas Meyers appeals the revocation of supervised release. This court can discern no relevant differences between parole and supervised release which would militate against the applicability of
Spencer. See United States v. Probber,
. This opinion has been circulated to all active members of this court, and it is their unanimous decision to overturn the following point of law articulated in
Dominguez-Carmona
and
Soto-Holguin:
the potential impact of challenged sentences on future sentencing proceedings constitutes a sufficient collateral consequence to render a controversy live even though the defendant involved has completed the sentence imposed. Despite overruling this point of law, this panel nonetheless does not question the ultimate outcome reached in both
Dominguez-Carmona
and
Soto-Holguin
on the issue of whether the defendants' completion of their sentences mooted the government’s appeals. In other words, those two opinions properly concluded that the defendants’ completion of their sentences did not render moot the government's challenge to the length of the imposed sentences. When the government is the party appealing the length of an imposed sentence as improperly short, the defendant's completion of that sentence does not moot the appeal because the government still alleges a remediable injury: the trial court's failure to impose the appropriate sentence pursuant to statute or the sentencing guidelines. In such an appeal, the government's asserted need for a longer sentence than that imposed can be remedied only by appeal.
