The principal question presented by this collateral attack upon a criminal conviction is the degree of retroactivity to be attached to our constitutional interpretation in
Arnold v. United States,
*501 On May 11,1979, appellant was convicted of grand larceny while armed, D.C.Code §§ 22-3202, -3812 (1981 & 1985 Supp.), and unauthorized use of a vehicle, D.C.Code § 22-3815 (1985 Supp.). 2 On direct appeal, appellant asked us to consider “[w]hether, as a matter of law or under the facts of the case, [his] consecutive sentence for unauthorized use of a motor vehicle merge[d] with his conviction for grand larceny of the same motor vehicle which arose from the same transaction.” On May 21, 1981, a division of this court rejected appellant’s contention and affirmed his convictions in an unpublished opinion. 3
On October 5, 1983, reaching the opposite conclusion on indistinguishable facts, another division held that the Double Jeopardy Clause of the Fifth Amendment prohibits separate convictions for grand larceny and unauthorized use of a vehicle arising out of the same transaction.
Arnold, supra,
I
On the afternoon of July 9, 1979, Eric Mann was driving through the District of Columbia on his way from Atlantic City, New Jersey, to his home in North Carolina. He stopped on Kenilworth Avenue, N.E., to examine his tires and a loose stereo speaker. As Mann did so, he noticed two strangers standing by a nearby fence. Suddenly these men, appellant and codefendant Melvin Thomas, approached Mann from behind, placed a sawed-off shotgun in his back, and ordered their captive back into the car. Mann was forced to drive for a while and then, at gunpoint, to hand over his watch and his wallet. At some point, appellant took over the wheel and the victim was moved into the back seat. About 30 to 45 minutes after the ride began, Mann was abandoned in Marlow Heights, Maryland, and appellant and Thomas drove off in his car.
Mann succeeded in stopping a passing motorist for help and went to a local police station to report the incident. The. police took him back to the neighborhood where the kidnapping began. After a ten-minute search, Mann spotted the stolen car in an alley, with Thomas leaning inside and appellant standing next to it. Both men fled. Thomas was apprehended after a brief chase and identified at the scene by Mann. Appellant was later arrested On a warrant and identified by Mann in a line-up and at trial.
Appellant received three concurrent sentences of fifteen to forty-five years imprisonment, including the term for his grand larceny while armed. 4 It is the consecutive sentence of eighteen to fifty-four months *502 for unauthorized use of a motor vehicle that appellant now challenges under the double jeopardy rule in Arnold. 5
II
In
Arnold,
we held that dual convictions for grand larceny and unauthorized use of a motor vehicle were improper. We reasoned that because the grand larceny contained within it the unauthorized use of the vehicle, and the unauthorized use conviction required proof of no fact which the grand larceny did not, the defendant had been subjected to multiple punishments for the “same” offense.
See Brown v. Ohio,
Our conclusion in
Arnold
was arrived at by looking at the facts of the case rather than by limiting our analysis to “abstract consideration of the statutes involved.”
In this regard, the record is crystal clear. Both offenses arose out of the same fact pattern; there was nothing in appellant’s unlawful use of a vehicle conviction that was not also used as proof of the grand larceny while armed. Under our holding in Arnold, we have no choice but to conclude that appellant’s unlawful use of a vehicle conviction violated his Fifth Amendment guarantee against double jeopardy, and that the resulting eighteen to fifty-four months sentence of consecutive imprisonment meted out by the trial court was unconstitutional.
Ill
The government concedes the unconstitutionality of the consecutive sentence of imprisonment, acknowledging, with admirable candor, “that the facts of this case cannot meaningfully be distinguished from Arnold. But even so,” it continues less generously, “appellant’s claim must fail.” The sole justification urged for keeping appellant incarcerated pursuant to an unconstitutional sentence is that this precise issue has been decided adversely to appellant on his direct appeal. The decision in Arnold, the government admits, would otherwise control.
In support of this position, the government cites
M.A.P. v. Ryan,
Decisions designated as not for publication shall not be cited to the court in any material prepared for the court except when the opinion is relevant under the doctrines of the law of the case, res judicata or collateral estoppel, or in a criminal action or proceeding involving the same defendant....
Id. § IX C (emphasis added). The combined effect of M.A.P. v. Ryan and IOP §§ VIII H and IX C, argues the government, precludes this division — though, strangely, not the Superior Court — from considering the acknowledged unconstitutionality of appellant’s sentence of imprisonment. Having unsuccessfully raised the merger issue on direct appeal, the argument goes, appellant must live with his defeat unless he can point to intervening authority from the Supreme Court or else persuade us to revisit the matter en banc. 7
The government, in making this argument, ignores the purpose behind our rule that one division cannot overrule another. The rule is designed to preserve uniformity in the decisions of this court. Arnold did not undermine that policy because its double jeopardy interpretation ran counter to no published opinion on the same point. Yet the government contends that a division such as this should disregard our otherwise binding decision in that case and thus rule differently from every other division that has confronted the issue since publication of Arnold 8 Instead, the government contends, we are bound to follow a prior unpublished decision which cannot be cited in any case other than the present. In our view the ideal of uniformity in the decisions of this court, as expressed in M.A.P. v. Ryan and our IOPs, is defied by the government’s position. 9
The government also fails to comprehend the true nature of a collateral attack. One primary purpose of § 23-110 is to enable convicted prisoners to escape the shackles of res judicata when constitutional rights have been violated or other illegalities have occurred in their sentencing. By its very definition, a collateral attack on a tainted sentence involves a challenge to the decision of the court that has previously adjudicated the issue. Despite this fact, § 23-110 requires the courts of the District of
*504
Columbia to be eternally vigilant in ensuring that prisoners are not subject to unlawful incarceration. For this reason we have necessarily held that strict principles of res judicata — and the government invokes them here in their harshest form — do not apply in these proceedings.
Pettaway v. United States,
Aside from its incompatibility with both our ideal of uniform decisions and the humane purpose of § 23-110, the government’s argument leads to an absurd result: it would penalize appellant for having correctly argued his appeal in the first place. A defendant who had failed to raise the merger contention on direct appeal, in contrast to appellant, would now be at liberty to reap the benefits of
Arnold
by way of a § 23-110 motion,
c.f. Garris v. United States,
IV
The question remaining, one not addressed by the government, is whether
Arnold
applies retroactively so as to benefit a defendant challenging a final conviction by way of collateral attack. “As a rule, judicial decisions apply ‘retroactively.’”
Solem v. Stumes,
After
Linkletter,
the Supreme Court was frequently called upon to determine the extent to which its new interpretations
*505
affecting the constitutional rights of criminal defendants should be retroactively applied. Relying upon a three-part test, the Court normally inquired into: “(a) the purpose to be served by the new standards, (b) the extent of the reliance of law enforcement authorities on the old standards, and (c) the effect on the administration of justice of a retroactive application of the new standards.”
Stovall v. Denno,
The outcome of the balancing test varied considerably. On one side of the scales some new rules received full retroactive effect in all subsequent cases.
E.g., Brown v. Louisiana,
This extensive array of chosen options drew charges, both from within
11
and without
12
the Court, that its application of the
Linkletter
doctrine rested on no principled basis. Perhaps the most influential of the critics was Justice Harlan. In two opinions,
Mackey v. United States,
In recent years, the Supreme Court has agreed with Justice Harlan’s belief that “[r]etroaetivity must be rethought.”
Johnson, supra
note 11,
The doubtful retroactivity attaching to new constitutional interpretations not falling within the bounds of
Johnson
was partially resolved two years later in
Stumes, supra,
More recently, the Supreme Court further refined the rethinking of retroactivity doctrine begun in
Johnson.
The setting of
Shea, supra,
*507
In the wake of
Johnson, Stumes
and
Shea,
it appears that the Supreme Court’s nonretroactivity doctrine has undergone a comprehensive revision since first launched in
Linkletter,
at least with respect to Fourth and Fifth Amendment violations. A modified version of the Harlan approach has prevailed with respect to cases coming before the Court on direct review, so that most cases not yet final can henceforth be expected to receive the benefit of the new rule.
Shea, supra,
470 U.S. at ---,
The broad principles emerging from the Supreme Court’s recent retroactivity decisions must be read subject to certain limitations. In particular, the Court has not given unqualified approval to Justice Harlan’s absolutist view that a new rule should be applied retroactively to
every
case not yet decided on direct appeal; in
Shea,
the Court specifically declined to consider “situations clearly controlled by existing re-troactivity precedents, such as where the new rule of law is so clear a break with the past that it has been considered nonretroac-tive almost automatically.” 470 U.S. at - n. 5,
Appellant claims on this collateral attack that our constitutional interpretation in
Arnold
should be applied retroactively so as to invalidate his sentence of eighteen to fifty-four months imprisonment for unauthorized use of a vehicle.
14
We need not concern ourselves here with the Supreme Court’s apparent rejection of the three
Sto-vall
factors when a conviction comes before it on direct review. A collateral attack, such as the present, remains generally subject to the
Stovall
balancing test. We are not required to weigh the
Stovall
factors in the present case, however, because
Arnold
is the classic example of “a ruling that a trial court lacked authority to convict or punish a criminal defendant in the first place.”
Johnson, supra
note 11,
Our previous rejection of appellant’s contention does not preclude his raising the same claim, citing intervening authority, by way of a § 23-110 collateral attack. On the merits, we hold that Arnold is fully retroactive, and that appellant is entitled to the benefit of it. We reverse and remand for vacation of the conviction and sentence for unauthorized use of a vehicle, both having been imposed in violation of appellant’s Fifth Amendment right not to be twice put in jeopardy for the same offense.
So ordered.
Notes
. D.C.Code § 23-110 (1981) provides, in relevant part:
(a)A prisoner in custody under sentence of the Superior Court claiming the right to be released upon the ground that (1) the sentence was imposed in violation of the Constitution of the United States or the laws of the District of Columbia, (2) the court was without jurisdiction to impose the sentence, (3) the sentence was in excess of the maximum authorized by law, (4) the sentence is otherwise subject to collateral attack, may move the court to vacate, set aside, or correct the sentence.
(b) A motion for such relief may be made at any time.
(c) ... If the court finds that (1) the judgment was rendered without jurisdiction, (2) the sentence imposed was not authorized by law or is otherwise open to collateral attack, *501 (3) there has been such a denial or infringement of the constitutional rights of the prisoner as to render the judgment vulnerable to collateral attack, the court shall vacate and set the judgment aside and shall discharge the prisoner, resentence him [or her], grant a new trial, or correct the sentence, as may appear appropriate.
******
(f) An appeal may be taken to the District of Columbia Court of Appeals from the order entered on the motion as from a final judgment on application for a writ of habeas corpus.
. At the time of appellant’s convictions these offenses were differently numbered at D.C.Code §§ 22-2201, -3202 (1973) and id. §§ 22-2204, -3202 respectively.
. Kirk v. United States, No. 79-998 (D.C. May 21, 1981).
. Appellant was also convicted of kidnapping while armed, D.C.Code §§ 22-2101, -3202 (1981), and armed robbery, id. §§ 22-2901, -3202.
. Codefendant Melvin Thomas was also convicted and sentenced for the crimes at issue in this case. Like appellant, he raised the merger issue on direct appeal. We rejected his contention, also in an unpublished opinion, on the same day as we disagreed with that of appellant. Thomas v. United States, No. 79-728 (D.C. May 21, 1981). Thomas joined appellant in renewing the merger argument in light of our subsequent Arnold decision, but did not appeal from the trial court’s denial of their § 23-110 motion.
. "[N]or shall any person," the Fifth Amendment guarantees, ‘be subject for the same offense to be twice put in jeopardy of life and limb....’’
.D.C.App.R. 40 (1985) provides, in relevant part:
(d) Petition for initial hearing en banc. A party, upon filing a brief, may request a hearing en banc by filing ten copies of a petition with the clerk. The petition shall not exceed ten pages in length. The clerk shall transmit the petition to the judges of the court who are in regular active service. A vote will be taken to determine whether the case will be heard initially en banc only if a judge in regular active service requests that a vote be taken.
(e) When hearing or rehearing en banc will be ordered. A majority of the judges in regular active service may order that an appeal or other proceeding be heard or reheard by the court en banc. Such a hearing or rehearing is not favored and ordinarily will not be ordered except (1) when consideration by the full court is necessary to secure or maintain uniformity of its decisions, or (2) when the proceeding involves a question of exceptional importance.
IOP § XI J provides:
Initial en banc hearing may be ordered if there is a determination that the case is controlled by a prior decision of the court which should be reconsidered or that the case is of exceptional importance. Initial en banc consideration may be ordered by the majority of the active judges of the court.
. See cases collected infra note 14.
. Another response to the M.A.P. v. Ryan argument is simply to point out that we are faced with two directly conflicting authorities from divisions of this court and we cannot follow both. Try as we might, we cannot avoid choosing between our affirmance on appellant’s direct appeal and the factually indistinguishable Arnold decision.
. In
Garris II
we applied
Arnold,
having already affirmed the challenged convictions on a direct appeal in which the merger issue was not raised.
Garris v. United States,

See, e.g., Beytagh, Ten Years of Non-Retroactivity Doctrine; A Critique and a Proposal, 61 Va.L.Rev. 1557 (1975); Hasler, Retroactivity Rethought: The Hidden Costs, 24 U.Me.L.Rev. 1 (1972); Haddad, "Retroactivity Should be Rethought A Call for the End of the Linkletter Doctrine, 60 J. Crim.L., Criminology & Police Sci. 417 (1969).
. The
Shea
majority justified its distinction between direct and collateral challenges by saying that it "properly rests on considerations of finality in the judicial process. The one litigant already has taken his [or her] case through the primary system. The other has not. For the latter, the curtain of finality has not been drawn. Somewhere, the closing must come." 470 U.S. at -,
. Because we previously rejected appellant’s merger claim on direct appeal we assume, without deciding, that our later decision in
Arnold
set forth a "new rule,” rather than merely applying an old one, and that a "true retroactivity question” is actually before us.
Fields v. United States,
We note in passing that we have applied
Arnold
in every reported case in which the issue has been raised on direct appeal.
Holt v. United States,
We have also applied
Arnold
retroactively in a situation similar, in some respects, to a collateral attack.
