George E. Jones, the appellant, brings this interlocutory appeal from the Superior Court’s denial of his motion to dismiss an indictment. Jones argues that two counts of the indictment are vague, and that the government’s prosecution on those counts is barred by the principles of double jeopardy and collateral estoppel. We hold that because Jones has never been placed in jeopardy in a proceeding related to the charged offenses, there is no valid claim of double jeopardy presented to this court that is ap-pealable interlocutorily. Accordingly, we dismiss the appeal for want of jurisdiction.
I.
The grand jury indicted Jones on two counts of distribution of cocaine, and one count of unlawful possession of drug paraphernalia. The indictment named Mark Pride and Wanda Collins as Jones’s co-defendants, charging each with one count of possession of cocaine. At the time of his arrest, Jones was on release under the supervision of the United States District Court for the District of Columbia, completing a sentence for conspiracy to distribute narcotics. See 18 U.S.C. § 3583 (1994) (governing imposition, modification, and revocation of supervised release). The United States Attorney for the District of Columbia elected to request a revocation of the supervised release based on these new offenses before they were tried in the District of Columbia Superior Court.
The district court held a full evidentiary hearing before the Honorable John G. Penn. Relying solely upon the charge of distribution of cocaine to Collins, the government argued that Jones’s supervised release should be revoked and that Jones should be incarcerated for all or part of the remainder of his release time. 1 The government presented the testimony of the arresting officer, who stated that he witnessed three apparent drug transactions: two between Jones and Collins, and one between Jones and Pride. Judge Penn denied the petition for revocation, stating that the government had failed to prove a criminal violation by a preponderance of the evidence. 2 Jones then filed a motion to dismiss the indictment in Superior Court, claiming that prosecution of the indictment was unconstitutional. The trial court denied the motion.
Jones raises three issues on appeal. First, he argues that principles of double jeopardy bar prosecution in Superior Court of the two counts of distribution of a controlled substance presented to Judge Penn in the supervised release revocation proceeding. Second, he contends that the counts alleging the distribution of cocaine are so vague that they do not provide sufficient information to evaluate a Fifth Amendment double jeopardy claim or satisfy the Sixth Amendment right to notice. Third, Jones claims that even if the two distribution counts in the indictment were not entirely barred by double jeopardy principles, the government should be collaterally estopped from relitigating the facts determined in the district court hearing.
*727 II.
Jones argues that the government initially placed him in jeopardy when it sought revocation of supervised release. A term of supervised release “is part of the sentence and is designated at the time of sentence to occur after the prisoner finishes serving a specific term of incarceration.”
United States v. Marmolejo,
We disagree that trial in Superior Court would violate the constitutional protection against double jeopardy. We conclude that Jones was not placed in jeopardy for any of the present offenses at the district court hearing to revoke his supervised release, a hearing of a type which is closely analogous in form and purpose to a hearing to revoke probation or parole. The Supreme Court has stated that such hearings are not criminal prosecutions for purposes of due process,
Gagnon v. Scarpelli,
A supervised release revocation hearing is the functional equivalent of a probation or parole revocation hearing. The same evidentiary rules apply, decisions are made according to similar guidelines and standards of proof, and the consequences that may result from a revocation are known to the defendant at the time of sentencing.
See
18 U.S.C. § 3583(e)(3) (providing that determination of revocation of supervised release must be made “pursuant to the provisions of the Federal Rules of Criminal Procedure that are applicable to probation revocation”);
United States v. Paskow,
III.
Ordinarily, this court has jurisdiction only over final orders and judgments of the Superior Court. D.C.Code § ll-721(a)(l) (1995). Because Jones appeals the denial of his motion to dismiss before a verdict or judgment has been entered, we must evaluate the court’s jurisdiction in light of the collateral-order exception to the final-order rule, promulgated in
Cohen v. Beneficial Industrial
*728
Loan Corp.,
The collateral-order doctrine allows this court to review a small class of orders which satisfy the following criteria:
To come within this “narrow exception” [to the rule against interlocutory appeals] a trial court order must, at a minimum, meet three conditions. First, it “must conclusively determine the disputed question,” second, it must “resolve an important issue completely separate from the merits of the action,” third, it must “be effectively unreviewable on appeal from a final judgment.”
Stein v. United States,
In addition to claiming that a trial on the charged offenses would violate the Double Jeopardy Clause, Jones claims that the indictment is so vague that it fails to provide an adequate basis to evaluate his Fifth Amendment double jeopardy concerns. Both claims implicate Jones’s right not to be •tried twice for the same offense.
See Joseph v. United States,
Jones would also have this court consider whether the distribution charges in the indictment are so vague as to violate his Sixth Amendment right to be informed of the nature and cause of a criminal accusation. Denial of a motion to dismiss an indictment for vagueness on Sixth Amendment grounds is not a collateral order.
See Midland
As
phalt Corp. v. United States,
Jones finally claims that the government is estopped from relitigating in Superi- or Court the charges that it sought and failed to prove in the district court supervised release revocation hearing. This court has not clearly addressed whether collateral estoppel in a criminal case is grounds for interlocutory review under the
Cohen
doctrine. Jones argues that because under
Ashe v. Swenson,
We disagree. That collateral estoppel in a criminal case has a constitutional dimension arising from the Double Jeopardy Clause does not fully answer the question whether such a claim in this ease is appeal-able on an interlocutory basis. This court has used, and now explicitly endorses, the following rule to determine whether it has jurisdiction to decide interlocutory appeals of collateral estoppel claims: if a defendant claims that at a prior jeopardy-attaching proceeding, a fact was determined in such a manner that, if the determination were adopted in the instant proceeding, the double jeopardy clause would foreclose the prosecution, this court will have jurisdiction to review the question.
See Turner v. United States,
Collateral estoppel may preclude a second prosecution — and thus give rise to an
*730
interlocutory appeal — even where the second prosecution is not for the “same offense” as defined in
Dixon,
509 U.S. at -,
We therefore agree with Jones that if he were in actual danger of a double-jeopardy violation because jeopardy had previously attached, and a fact determined in the first proceeding would foreclose the subsequent prosecution, the collateral-order rule would provide us with jurisdiction to hear an interlocutory appeal on the collateral estoppel claim. As we conclude that jeopardy has never attached with respect to the present offenses, and Jones’s claim of collateral es-toppel therefore cannot derive from the constitutional prohibition on double jeopardy, we dismiss Jones’s collateral estoppel claim for lack of jurisdiction. 4
In conclusion, because this is an interlocutory appeal, this court only has jurisdiction if Jones is in danger of being placed in double jeopardy.
See Coleman v. United States,
So ordered.
Notes
. Although limiting its allegation of Jones’s violations of his conditions of release to the sale to Collins, the government also introduced testimony regarding the distribution to Pride.
. In denying the motion to revoke supervised release, Judge Penn stated:
Taking everything to conclusion, I find at this time that the government has failed to establish by a preponderance of the evidence that Mr. Jones may have committed the matter and offense [being prosecuted in Superior Court.] There’s some — several matters that I’m concerned about. One was ... I’m not sure the police officer could observe from his place, where he was hiding or observing from, exactly what was taking place ... he never did testify that he actually saw an item pass from Mr. Jones to Ms. Collins. He did testify at one point that he saw money or what appeared to him to be currency pass.
.... [W]ith respect to the alleged violation in this case, I will deny it, and as far as this alleged violation is concerned, [Mr. Jones] will continue to maintain his present status.
. This would occur, for example, where the government sought to relitigate facts developed at a suppression hearing it had already lost in a separate prosecution against the same individual. An order rejecting a collateral estoppel argument that seeks merely to exclude evidence at trial, rather than foreclose a second prosecution, is not an appealable collateral order.
See United States v. Mock,
. Although this court has previously expressed confidence that the government would appropriately move to dismiss interlocutory appeals that, under
Abney, supra,
claim double jeopardy where no prior jeopardy had attached,
Coleman v. United States,
Instead, the government argues that evidentia-ry collateral estoppel has no application in the criminal sphere unless it is compelled by the double jeopardy clause. This court has not yet resolved the question whether collateral estoppel applies where there is no claim of double jeopardy, but where the defendant still proposes to meet his burden of showing not only that the fact sought to be excluded was "resolved by final judgment in a prior legal action,”
Laughlin v. United States,
Because this is an interlocutory appeal, we are concerned at this juncture only with collateral estoppel claims that implicate double jeopardy. Thus, in this appeal, we do not reach the issue of the application in criminal proceedings of evi-dentiary collateral estoppel.
