The government appeals from the District Court’s order reducing Taylor’s sentence pursuant to Fed.R.Crim.P. 35. 1 On February 23, 1982, Taylor entered a plea of guilty to a violation of 18 U.S.C. § 113(b), *116 assault with intent to commit a felony, and was sentenced by the District Court to a term of 7V2 years. On June 4, 1982, Taylor filed a Rule 35 motion to reduce sentence. On December 16, 1983, approximately 18 months after the motion was filed, the court entered its order, reducing Taylor’s sentence to time served. 2 The government concedes that the defendant did nothing to prolong the court’s decision and, in fact, requested on two occasions that the court rule on his motion.
The government filed a motion for reconsideration, contending that the lapse of time had deprived the court of jurisdiction under Rule 35. The court held a hearing on January 13, 1984, at which time the District Judge stated,
for the record before ruling on the case that I acted deliberately in this case, that the offense was a serious offense. Of course, the sentence was a fairly harsh sentence, and I had no intention of granting a Rule 35 motion at the time that it was filed, that I fully intended for Mr. Taylor to stay in the institution for some time before I did rule on his Rule 35 motion, so I would have an opportunity to see how he handled his incarceration, so it was not — the delay on my part was a very intentional delay in action upon the motion. I would not have granted the motion within the 120 days. On the other hand, if I had felt that I could not grant a Rule 35 motion with this kind of delay, I would not have imposed a seven-and-a-half year sentence in the first place____ [emphasis added]
The District Court thereupon took the motion to reconsider under advisement. After the government on July 13, 1984, called the court’s attention to the fact that its motion for reconsideration had been under advisement for more than 30 days, the court denied the motion on August 21, 1984. This appeal followed.
I.
The government does not contend that the District Court did not retain jurisdiction to act on appellant’s motion for a reasonable time after the 120-day time limit specified in Rule 35(b) had elapsed. 3 Rather, it *117 argues that even if a district judge may extend consideration of a timely Rule 35(b) motion for a reasonable period beyond the 120-day limit, “the district court’s delay in this case was unreasonable because of a delay of 18 months in and of itself was unreasonable.” Moreover, it contends that, in holding appellee’s Rule 35 motion in abeyance “so I would have an opportunity to see how he handled his incarceration,” the District Judge usurped the role of the Parole Commission and committed an abuse of discretion.
Appellee responds that in considering the reasonableness of the additional time taken before an order reducing sentence was entered, the courts have declined to adopt a
per se
limit such as the government proposes.
See United States v. Smith,
Those circuits adhering to the rule that the district courts retain jurisdiction over timely filed Rule 35 motions for a reasonable period, see note 3 supra, have recognized as an important corollary thereto
that one purpose of the Rule’s time limitation is to ‘assure that the district court’s power to reduce sentence will not be misused as a substitute for the consideration for parole by the Parole Board,’ Stollings,516 F.2d at 1289 , by ‘hold[ing] a timely motion for reduction of sentence in abeyance for months or years and then seeking] to grant it on the basis of *118 defendant’s conduct in prison,’ [United States v.] Mendoza, 565 F.2d [1285] at 1290 [5th Cir.1978].
United States v. Krohn,
Even if, once a timely Rule 35(b) motion has been filed, a district court retains jurisdiction for a reasonable time to reduce sentence after the 120-day time limit specified in the rule has expired, no period of extension of whatever length is reasonable if it has been allowed by the court for a purpose in contravention of the rule. In the instant case, the District Judge clearly delayed acting on appellee’s motion in order to take developments subsequent to sentencing into account, rather than to reconsider his original decision. Contrary to appellee’s argument, it is not necessary that a district judge deliberately override a decision of the Parole Commission to impermissibly usurp the Commission’s role. The facts of the instant case are precisely those that Judge Haynsworth suggested in
United States v. Stollings,
The time limitation appears to have as its dual purpose the protection of the district court from continuing and successive importunities and to assure that the district court’s power to reduce a sentence will not be misused as a substitute for the consideration of parole by the Parole Board. We need not speculate, however, that a judge would hold a timely motion for reduction of sentence in abeyance and unacted upon for months or years and then seek to grant it on the basis of the defendant’s conduct in prison.
Since we conclude that, in substituting its judgment for that of the Parole Commission, the District Court abused its discretion when it reduced appellant’s sentence, we decline to consider whether any delay of a particular duration or longer in acting upon a Rule 35(b) motion is unreasonable per se. However, we do question whether an 18-month delay, such as that present in this case, could be considered reasonable under any set of circumstances that we have been able to imagine.
II.
The analysis above, however, does not fully resolve the case. There remains the question of whether the District Judge’s statement — that if he had not believed that he could act as he ultimately did, he would not have imposed such a lengthy sentence — warranted modification of defendant's sentence under Rule 35(a). He urges
*119
that the instant case is equivalent to
DeMier, supra,
and
United States v. Ruster,
In
United States v. Addonizio,
Although
Addonizio
involved a motion under § 2255, we regard it as equally relevant to Rule 35 motions. While Rule 35 and § 2255 are not coterminous,
United States v. Santora,
In the
DeMier
case, the district judge was advised by the Probation Office prior to sentencing that the defendants could be expected to serve 16-20 months of their three year sentences, based upon then current parole guidelines. In fact, the Parole Commission adopted a 40-52 month guideline. The defendants did not begin serving their sentences until disposition of their unsuccessful appeal, nearly one year after their sentences were first imposed. Consequently, the Probation Office made its report based upon the 1978 guidelines, while the Parole Commission applied the 1979 guidelines. The district court concluded that “[t]he important factual circumstance is that this Court was not furnished accurate information at the time it imposed sentence in regard to whether the 1978 or the 1979 guidelines would be applied by the Parole Commission when it decided how long it would keep defendants in custody.”
United States v. DeMier,
The appellate court in
DeMier
attempted to distinguish
Addonizio
on the basis that the district judge had not acted because his expectations had been frustrated by Parole Commission’s subsequent application of its guidelines, but because he was furnished with misinformation prior to sentencing about which guidelines would be applied.
Even if we were persuaded by the reasoning in
DeMier,
which we are not, that case is logically distinguishable from the instant case. The District Judge below did not rely on misinformation provided by a Probation Officer, or anyone else. Rather, if the sentencing judge’s subjective intent is being frustrated, it is as the result of his own misunderstanding of the law. In
Rusten,
in imposing a sentence of 15 years on the defendant, the trial court inquired of the Probation Officer whether the sentence “actually amounts to about 48 months,” to which the Probation Officer replied, “48 to 60 months, your honor.”
Moreover, the court in
Rusten
made no reference to
Addonizio.
Rather, it relied, as did the district court in
DeMier,
on the principle that “[w]hen a trial judge relies on materially false or unreliable information in sentencing a defendant, the defendant’s due process rights are violated.”
III.
In concluding as we have above, we are not insensitive to the fact that any misapprehensions on the part of the District Judge that may have affected the length of appellant’s sentence, although lawfully imposed and within statutory limits, were totally beyond his control. We were advised at oral argument that the government has undertaken to recommend to the Parole Commission, if the government prevailed in this case on appeal, that appellant be placed under parole supervision for the remainder of his original sentence rather than being returned to an institution, and that the Parole Commission has indicated its likely assent to that recommendation.
The order of the District Court is vacated and the case remanded for reinstatement of the original sentence.
Notes
. Rule 35. Correction or Reduction of Sentence
(a) Correction of Sentence. The Court may correct an illegal sentence at any time and may correct a sentence imposed in an illegal manner within the time provided herein for the reduction of sentence.
(b) Reduction of Sentence. The Court may reduce a sentence within 120 days after the sentence is imposed or probation is revoked, or within 120 days after receipt by the court of a mandate issued upon affirmance of the judgment or dismissal of the appeal, or within 120 days after entry of any order or judgment of the Supreme Court denying review of, or having the effect of upholding, a judgment of conviction or probation revocation. Changing a sentence from a sentence of incarceration to a grant of probation shall constitute a permissible reduction of sentence under this subdivision.
. Although not specified in the motion or in the order reducing sentence, it is clear that the motion was made and granted pursuant to subsection (b) of Rule 35, for reduction of a lawful sentence, rather than subsection (a), providing for correction of an illegal sentence or a sentence illegally imposed.
. By its terms, the 120-day time limit set forth in Rule 35(b) applies to the court, not the defendant. Moreover, Rule 45(b) states that "the court may not extend the time for taking any action under Rules 29, 33, 34 and 35, except to the extent and under the conditions stated in them.” Nevertheless, prior to the Supreme Court's decision in
United States
v.
Addonizio,
In
Kajevic,
the Seventh Circuit undertook a detailed examination of the evolution of Rule 35(b). It found that the rule’s predecessors, the Notes of the Advisory Committee and the
Addonizio
dictum, as well as the literal language of the rule and Rule 45(b), all suggested that the 120-day limit was mandatory and jurisdictional. Were we writing on a clean slate, that analysis might be persuasive. However, those circuits that took the opposing view before
Addonizio,
did so "despite the acknowledgment that a liter
*117
al reading of Rules 35(b) and 45(b) would lead to a contrary conclusion.”
Krohn,
This Circuit has not yet ruled on the question of whether the time limit in Rule 35 is jurisdictional, although in
United States v. Blanton,
On April 29, 1985, the Supreme Court transmitted to Congress an amended version of Rule 35(b), which incorporates the predominent application of the rule:
(b) REDUCTION OF SENTENCE. A motion to reduce a sentence may be made, or the court may reduce sentence without motion, within 120 days after the sentence is imposed probation is revoked, or within 120 days after receipt by the court of a mandate issued upon affirmance of the judgment or dismissal of the appeal, or within 120 days after entry of any order or judgment of the Supreme Court denying review of, or having the effect of upholding, a judgment of conviction or probation revocation. The court shall determine the motion within a reasonable time. Changing a sentence from a sentence of incarceration to a grant of probation shall constitute a permissible reduction of sentence under this subdivision.
*118
. Taylor cites
United States v. Ochs,
. In the
Dean
case, in which the court rejected the argument that a sentence based upon erroneous information provided by a probation officer was subject to reduction under Rule 35(a), the court distinguished
DeMier
in part on the basis that the motion in
DeMier
was granted under Rule 35(b), rather than Rule 35(a).
. Title 28 U.S.C. § 2255 provides, in pertinent part:
A prisoner in custody under sentence of a court established by Act of Congress claiming the right to be released upon the ground that the sentence was imposed in violation of the Constitution or laws of the United States, or that the court was without jurisdiction to impose such sentence, or that the sentence was in excess of the maximum authorized by law, or is otherwise subject to collateral attack, may move the court which imposed the sentence to vacate, set aside or correct the sentence.
... If the court finds that the judgment was rendered without jurisdiction, or that the sentence imposed was not authorized by law or otherwise open to collateral attack, or that there has been such a denial or infringment 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 or resentence him or grant a new trial or correct the sentence as may appear appropriate.
. Thus, our disposition of plaintiff's contention, that reduction of his sentence under Rule 35 was not justified on the basis of the sentencing judge’s misapprehension of the scope of his discretion under that rule, necessarily forecloses him from raising the same contention in the future under § 2255, although he would not be foreclosed from making a § 2255 application on some other ground. See 3 C. Wright, supra, § 602.
. It is not clear that the court recognized the full import of
Addonizio,
since it appears to have regarded
United States v. Lacy,
. The court reasoned that "Congress has not attempted to deprive district judges of their traditional sentencing power. Nor has the Congress attempted to transfer the power to impose all sentences to the Parole Commission.”
