On January 15,1969, appellant was apprehended on a parole violator warrant and returned to a federal institution pending a parole revocation hearing. He filed a petition for a writ of habeas corpus claiming that he was entitled to pre-hearing release on bail. The district court denied the petition and an appeal was taken to this court.
The question before us is whether there is any right, statutory or constitutional, to be admitted to bail pending a parole revocation hearing. We must first deal, however, with the government’s contention that the appeal has been mooted by the expiration of appellant’s sentence on May 12, 1969.1
The doctrine of mootness is derived from Article III, § 2, of the Constitution, which makes federal jurisdiction turn in part on the existence of a case or controversy. Liner v. Jafco, Inc., 375 U.S. 301, 306 n. 3, 84 S.Ct. 391, 11 L.Ed.2d 347 (1964). The fundamental policies underlying the doctrine appear to be two and awareness of them is essential to dealing with this complex area of the law. The first is that the courts, for reasons of judicial economy, ought not to decide cases in which the controversy is hypothetical, a judgment cannot grant effective relief, or the parties do not have truly adverse interests. Second, it is a premise of the Anglo-American judicial system that the genuinely conflicting self-interests of parties are best suited to developing all relevant material before the court. See Sibron v. New York, 392 U.S. 40, 57, 88 S.Ct. 1889, 20 L.Ed.2d 917 (1968); Lord v. Veazie, 49 U.S. (8 How.), 251, 12 L.Ed. 1067 (1850); R. Robertson & F. Kirkham, Jurisdiction of the Supreme Court of the United States § 271 (Wolf-son & Kurland ed. 1951); Note, Cases Moot on Appeal, 103 U.Pa.L.Rev. 772, 773-75 (1955); Note, “Moot” Administrative Orders, 53 Harv.L.Rev. 628, 629-30 (1940). Hence, when the circumstances out of which a controversy arise change so as to raise doubt concerning the adversity of the parties’ interests, courts ordinarly dismiss cases as moot, regardless of the stage to which the litigation has progressed.
These considerations doubtless resulted in the Supreme Court’s holding that the expiration of a criminal sentence moots questions raised during the antecedent proceedings. St. Pierre v. United States, 319 U.S. 41, 63 S.Ct. 910, 87 L.Ed. 1199 (1943). The narrowing of this rule to permit review when the appellant *333may be subject to collateral consequences flowing from his conviction 2 is responsive to the same policies. Where an appellant may be deprived of rights or subpected to disabilities by virtue of the prior conviction, the court can be confident that there is a genuine conflict between the parties. However, appellant argues that several other limitations on the mootness doctrine — all responsive to the same policies — are applicable to him.
We come first to his contention that the substantive issue presented by this case is of public importance, and as such, warrants retention of jurisdiction. This position is not without some support. However, we are constrained to disagree.
The principal ease relied upon by appellant is Friend v. United States, 128 U.S.App.D.C. 323, 388 F.2d 579 (1967). There review was sought of the revocation of a conditional release of appellant from a mental institution. The court reached the merits, despite the fact that another conditional release had been granted while the appeal was pending, saying:
“[H]is circumstances are in many respects similar to those which have led to the ‘continuing controversy’ limitation on the mootness-doctrine — broadly, that cases are not made moot by the expiration of orders of brief duration capable of future repetition. Both doctors who testified at the hearing thought it improbable that appellant would consistently obey release conditions. His complete hospital detention is usually for a relatively brief time, not likely to persist long enough to finish appellate review. The issue as to the proper construction of § 301(e) [of tit. 24, D.C. Code] is continuing and of public importance, and review is not precluded by mootness. See Southern Pacific Terminal Co. v. ICC, 219 U.S. 498, 31 S.Ct. 279, 55 L.Ed. 310 (1911); Gay Union Corp. v. Wallace, 71 App.D.C, 382, 112 F.2d 192, cert. denied, 310 U.S. 647, 60 S.Ct. 1098, 84 L.Ed. 1414 (1940); Boise City Irr. & Land Co. v. Clark, 131 F. 415, 419 (9th Cir. 1904).” 388 F.2d at 581 (footnote omitted).
The foregoing quotation and the eases cited therein make it clear that the court relied upon the recurring controversy limitation, which for the reasons stated below we do not think is applicable here, rather than upon the notion that the public importance of the question alone is an adequate jurisdictional basis.3
Moreover, while we recognize the desirability of judicial determinations of important questions, we think that this interest, standing alone, does not prevent a case from being dismissed as moot. The case or controversy requirement and its corollary, the mootness doctrine, serve to assure that courts will decide such questions only after the vigorous development of the issues which is the goal of the adversary system. To proceed to decide questions without the assistance which the system provides entails the risk of ill-considered judgments which would ultimately be detrimental to the interests urged upon us as justifying such action. This is the fundamental constitutional policy and we therefore cannot retain jurisdiction on this ground.
Next, appellant claims that the substantive question he raises in this appeal is a recurring one and that he consequently comes within the rule of Southern Pacific Terminal Co. v. ICC, 219 U.S. 498, 31 S.Ct. 279, 55 L.Ed. 310 (1911), and its progeny. That case held that an *334appeal from an expired order of the Commission was not moot because the controversy involved was of a continuing nature. The Court said:
“The questions involved in the orders of the Interstate Commerce Commission are usually continuing (as are manifestly those in the case at bar) and their consideration ought not to be, as they might be, defeated, by short term orders, capable of repetition, yet evading review, and at one time the government, and at another time the carriers, have their rights determined by the Commission without a chance of redress.” 219 U.S. at 515, 31 S.Ct. at 283. See also, e. g., Hadge v. Second Federal Savings and Loan Association of Boston, 409 F.2d 1254, 1255 (1st Cir. 1969).
Appellant argues that an order denying bail pending a parole revocation hearing is just the sort of short-term order to which the Court spoke in Southern Pacific. If bail is not granted, parole will either be revoked or continued long before an appellate court can review the decision of the district court. Moreover, it is argued that the issue involved here is raised by virtually every arrest on a parole violator warrant. Hence, appellant contends that our decision is controlled by Southern Pacific. We do not agree.
The recurring controversy doctrine does, as appellant argues, result in courts retaining jurisdiction after the expiration of administrative orders. However, an element which is present in the recurring controversy cases is absent here. When an order of a regulatory body such as an I.C.C. order is challenged, the party seeking review remains subject to regulation by the agency. Hence, despite expiration of the order sub judice, there is a substantial likelihood of a repetition of the order, which would give rise to the same controversy. Thus, it is not only the legal issue which recurs in those eases, as is true in the case at bar, but the effect on the person challenging the order. This circumstance serves to warrant the continued vitality of the litigation. See Diamond, Federal Jurisdiction to Decide Moot Cases. 94 U.Pa.L.Rev. 125, 136 (1946); cf. Gay Union Corp. v. Wallace, 71 App.D.C. 382, 112 F.2d 192, 195 (1940), cert. denied, 310 U.S. 647, 60 S.Ct. 1098, 84 L.Ed. 1414 (1941).
In this case appellant has been unconditionally released from custody. The likelihood of his again being placed in the situation of which he complains is speculative. While appellant may be genuinely concerned with,the outcome of this litigation, the courts traditionally have not undertaken an examination of the bona fides of litigants in these circumstances. Where there has been no appreciable likelihood of the repetition of the order complained of with respect to the appellant, the recurring question doctrine has not been applied. See Spreckels Sugar Co. v. Wickard, 75 U.S. App.D.C. 44, 131 F.2d 12 (1941); Diamond, supra, at 136; cf. United States v. W. T. Grant Co., 345 U.S. 629, 633, 73 S.Ct. 894, 97 L.Ed. 1303 (1953); United States v. Hamburg-Amerikanische, etc., 239 U.S. 466, 475, 36 S.Ct. 212, 60 L.Ed. 387 (1916); United States v. Aluminum Company of America, 148 F.2d 416, 448 (2d Cir. 1945) (sitting as court of last resort); Note, Cases Moot on Appeal, 103 U.Pa.L.Rev. 772, 784 (1955).4
*335This brings us to the most difficult aspect of this issue. Although appellant has acted diligently in seeking judicial review of the denial of bail, the parole revocation process moved too quickly for such a claim to reach the appellate stage before the hearing was held.5 Since Sibron v. New York raises questions concerning any application of the mootness doctrine which would bar review of this claim, we must carefully consider its implications.
In Sibron the appellant had been convicted of possession of heroin and sentenced to six months’ imprisonment. He claimed that evidence introduced at his trial was seized in violation of the Fourth Amendment and appealed from his conviction. Since state law precluded release on bail pending appeal, Sibron had served the entire sentence prior to oral argument in the Supreme Court. The Court nevertheless held that the case was not moot, reasoning that Sibron might suffer collateral consequences from his conviction and emphasizing the importance of “keeping open avenues of judicial review of deprivations of constitutional right” at levels of “low visibility in the criminal process.” 6 392 U.S. at 50-58, 88 S.Ct. at 1897.
The Court’s sweeping language and its manifest concern that the doctrine of mootness might consign “low-visibility” criminal cases to a constitutional limbo has led some courts to read Sibron *336as abandoning traditional notions of mootness, particularly the requirement of a continuing personal stake in the litigation, when constitutional claims are raised on appeal. See, e. g., Esteban v. Central Missouri State College, 415 F.2d 1077, 1079 n. 1 (8th Cir. 1969). While this may well be the Court’s intention, at least in some cases, we cannot read Sibron broadly enough to cover the case at bar.
To begin with, Sibron was challenging a criminal conviction and therefore had a substantial interest in a victory in order to clear his record.7 While this may not be sufficient, in and of itself, to satisfy the case or controversy requirement, the Court makes it clear that, together with a possibility of collateral consequences, it will suffice. The Court’s comments concerning “low visibility” cases must, therefore, be read in the light of the fact that Sibron did have a personal interest of the conventional sort.
Moreover, even assuming that the Court in Sibron meant to articulate an exception to the mootness doctrine rather than merely to advance a persuasive reason for broadening the concept of personal interest, but see Hall v. Beals, 396 U.S. 45, 90 S.Ct. 200, 24 L.Ed.2d 214 (U.S. Nov. 24, 1969), Marchand’s case would not fall within the exception. The particular problem dealt with in Sibron was that traditional notions of mootness, combined with the New York statute prohibiting bail pending appeal, insulated an entire class of cases from review by the Supreme Court. In the instant case, however, it is the peculiarities of petitioner’s circumstances rather than the characteristics of a class which preclude review.8 Mar-chand has no further interest in the administration of the parole system. On the other hand, one whose parole has been revoked but who is still serving sentence would be subject to the continuing jurisdiction of the parole board, has a personal stake in the litigation, and therefore come within the recurring controversy doctrine discussed above. Review, therefore, is not cut off in all similar cases. Hence, the case is moot.
Although we do not reach the merits in this case, much may be said for Congressional consideration of the desirability of release on bail pending a hearing on revocation of parole. Such consideration should include the fact that the granting of bail pending appeal postpones the commencement of service, although not the total length of sentence, but if a defendant were bailed pending a hearing on revocation of his parole, under the present statutory scheme, the date of the termination of sentence would not be extended. Hence, the defendant would receive free time pending his revocation hearing.
The judgment of the District Court is vacated and the case remanded with instructions to dismiss the petition as moot.
