Opinion for the Court filed by Circuit Judge EDWARDS.
This case requires us to examine the question of whether a federal criminal defendant can obtain postconviction relief pursuant to the common law writ of audita querela. Appellant, Wilfredo Ayala, a Peruvian national, was sentenced in 1987 to two years in prison for conspiracy to distribute cocaine and is currently on parole. During Ayala’s imprisonment, the Immigration and Naturalization Service (“INS”) initiated deportation proceedings against him based on his drug conviction. Arguing that the prospect of deportation made the continuing effect of his conviction inequitable, Ayala subsequently moved to vacate the conviction by a writ of audita querela. The District Court denied the motion on the ground that Ayala could collaterally attack his conviction only through a motion under 28 U.S.C. § 2255 (1982). See United States v. Ayala, Crim. No. 87-11 (D.D.C. Oct. 27, 1988), reprinted in Appendix (“A.”) 46.
We agree that a defendant in Ayala’s position may not rely on the writ of audita querela to challenge his conviction, and consequently we affirm. The only circumstance, if any, in which the writ could furnish a basis for vacating a criminal conviction would be if the defendant raised a legal objection not cognizable under the existing scheme of federal postconviction remedies. Ayala, by his own admission, does not present such an objection on appeal. We remand the case, however, so that Ayala may pursue whatever relief might be available to him under section 2255.
I. Background
In January of 1987, Ayala was charged with distributing 500 grams of cocaine and with conspiracy to distribute the same quantity of that drug. See Record Documents Nos. 2, 3. Pursuant to a plea bargain, Ayala pleaded guilty to the conspiracy charge in exchange for the recommended dismissal of the substantive charge. The District Court sentenced Ayala to two years’ imprisonment and a four-year term of special parole. See Record Document No. 14. Ayala served approximately 16 months in prison before being released on the basis of statutory good-time deductions.
During Ayala’s imprisonment, the INS initiated deportation proceedings against Ayala, who entered the United States in 1982 on a business and tourism visa. See Points and Authorities in Support of Motion for Writ of Audita Querela (“Motion”) *427 11 3, reprinted in A. 38-39. 1 Although the record contains no information on these proceedings beyond what Ayala alleges in his pleadings below, it appears that the INS’ “show cause” order was based on 8 U.S.C. § 1251(a)(ll) (1988), which provides for deportation “upon the order of the Attorney General” of any alien who “has been convicted of a violation of, or a conspiracy to violate, any law or regulation of ... the United States ... relating to a controlled substance.” See Motion ¶ 4, reprinted in A. 39.
Ayala subsequently filed a motion with Judge Johnson, the same judge who initially sentenced him, to vacate his conviction pursuant to the writ of audita querela. The theory of the motion was that the prospect of deportation made the continuing effect of the conviction unfair. See Motion HU 7-8, reprinted in A. 41-43. In support of this contention, Ayala alleged in his motion that he had furnished and was continuing to furnish assistance to the Government in its efforts to prosecute other drug defendants, that deportation would cause undue suffering to him and to an American woman with whom he was engaged in a loving relationship, and that outside his one-time involvement with drugs he had lived and planned to live within the confines of the law. See id. 111Í 5, 7-9, reprinted in A. 40-44.
The District Court denied Ayala’s motion.

United States v. Kimberlin,
II. Analysis
The common law writ of
audita querela
permitted a defendant to obtain “relief against a judgment or execution because of some defense or discharge arising subsequent to the rendition of the judgment.” 11 C. Wright & A. Miller, Federal Practice and Procedure § 2867, at 235 (1973). Although historically
audita querela
existed as a remedy primarily for judgment debtors,
see id.,
it apparently has been recognized as a remedy for criminal defendants in at least some state jurisdictions.
See, e.g., Balsley v. Commonwealth,
The authority of federal courts to recognize common law postconviction remedies is governed by the Supreme Court’s decision in
United States v. Morgan,
The one circuit court of appeals to address the question expressed skepticism on whether a niche exists for
audita querela
within the scheme of federal postconviction remedies.
See United States v. Kimberlin,
Several district courts, however, have purported to find "gaps" in the federal postconviction remedial structure susceptible of being filled by the writ of audita querela. See United States v. Acholonu,
*429
Although Ayala clearly framed his motion with this theory in mind, we believe that the District Court properly declined to afford Ayala relief on this ground. The
Salgado
and
Ghebreziabker
courts appear mistaken, as a historical matter, in their conclusion that
audita querela
furnishes a purely “equitable” basis for relief independent of any legal defect in the underlying judgment. Commentators and jurists since the time of Blackstone have emphasized the need to show a postjudgment contingency supplying a “matter of discharge” or “defense.” 3 W. Blackstone, Commentaries *405-06.
6
Usage in state criminal practice, too, suggests that the distinction between
audita querela
and other forms of postconviction relief lies not in the
character
of the grounds for voiding the judgment, but rather in the
timing
of the occurrence of these grounds.
See, e.g., Balsley v. Commonwealth,
We recognize that the “pure equity” variant of audita querela, endorsed in Salga-do and Ghebreziabher, purports to add a new remedy in the federal postconviction remedial scheme. However, we do not believe that the “gap filling” allowed by Morgan permits a court to redefine a common law writ in order to create relief not otherwise available in the federal postconviction remedial scheme. See note 8 supra. In short, because the so-called “pure equity” variant of audita querela finds no support in the historical definition of the writ, the authority of federal courts to use it as a “gap filler” under the All Writs Act is open to serious doubt.
Given the posture of this case, however, we need not definitively resolve the issue of whether the writ of audita querela ever supplies a basis for vacating a federal criminal conviction. At oral argument before this court — perhaps sensing the infirmities of the “pure equity” conception of audita querela —the appellant abandoned the equitable claims that had been presented to the District Court. He now puts sole reliance on the contention, raised for the first time on appeal, that the Government assured him that he would not be deported if he pleaded guilty and testified against other drug defendants. Ayala maintains that the Government’s failure to deliver on this promise, renders his plea involuntary under the due process clause, *430 and makes his deportation additional criminal punishment under the double jeopardy clause. Both of these claims are clearly cognizable in a section 2255 proceeding. 9 Consequently, like the Seventh Circuit in Kimberlin, we are constrained to affirm the District Court’s ruling that Ayala’s only proper remedy is a motion under section 2255. 10
Moreover, because Ayala did not present his constitutional arguments below, we are not now in a position to address these claims as if they had been properly raised by a section 2255 motion. At oral argument, Ayala indicated that he would be satisfied with a remand so that he could pursue his due process and double jeopardy claims under section 2255. Because the Government indicated that it had no objection to such a disposition, and because we see no point in obliging Ayala simply to refile his motion with a different caption, we will remand with instructions to the District Court to treat Ayala’s original motion, subject to appropriate amendments, as having been filed under section 2255. We express no view, of course, on the merits of Ayala’s constitutional claims. 11
III. ConclusioN
The Supreme Court’s decision in
United States v. Morgan,
It is so ordered.
Notes
. Ayala alleged in his motion that a detainer was lodged against him and that he posted a $10,000 bond so that he could remain free pending the outcome of the deportation proceedings. See id.
. Writs of coram nobis, coram vobis, audita querela, and bills of review and bills in the nature of a bill of review, are abolished, and the procedure for obtaining any relief from a judgment shall be by motion as prescribed in these rules or by an independent action.
Ff.d.R.Civ.P. 60(b).
.The Supreme Court and all courts established by Act of Congress may issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law.
Id.
. The Court also rejected the suggestion that
coram nobis
relief was foreclosed by Rule 60(b). This provision’s express abolition of the writ of
coram nobis,
the Court held, is limited to civil proceedings.
See id.
. The court in
Acholonu
recognized the availability of
audita querela
in federal criminal proceedings generally but held that it furnished no ground for vacating the defendants conviction in that case. See
.
See also Humphreys v. Leggett,
. Coram nobis is recognized as providing relief parallel in scope to that provided by section 2255. See 3 W. LaFave & J. Israel, Criminal Procedure § 27.10(c), at 404 (1984).
. To be sure, not
all
postjudgment changes in law may be raised in a section 2255 proceeding.
See Teague v. Lane,
— U.S. -,
. Because he is currently on parole, Ayala remains in federal "custody” for purposes of section 2255.
See Jones v. Cunningham,
. Such a disposition is consistent with the procedures governing section 2255 proceedings because Ayala filed his motion for
audita querela
with the same District Court judge, Judge Johnson, who initially sentenced him, and because Ayala has not previously sought relief from Judge Johnson pursuant to section 2255.
See
28 U.S.C. § 2255; Rules Governing Section 2255 Pro-cef.dings 4(a). Ayala is differently situated in both respects from the defendant in
Kimberlin. See
.We also express no view on whether the District Court may entertain any double jeopardy challenge by Ayala before the INS issues a final deportation order.
