Mr. Vauda Virgle Shipp, Jr., appeals the district court’s denial of his 28 U.S.C. § 2255 habeas petition. We granted a certificate of appealability (“COA”) on one issue: whether
“Chambers v. United States,
— U.S. -,
I.
On September 14, 2005, Mr. Shipp was convicted of possessing a firearm after a felony conviction. At sentencing, he was categorized as an “armed career criminal” pursuant to the Armed Career Criminal Act, 18 U.S.C. § 924(e)(2) (2009) (the ACCA), based upon three predicate state convictions: (1) a 1984 conviction for assault with a dangerous weapon, (2) a 1984 conviction for possession of marijuana with intent to distribute, and (3) a 1987 conviction for escape for failure to report to a penal institution after he was permitted to be away on an official pass. Under § 924(e)(2), armed career criminals are subject to a statutory minimum of fifteen years’ imprisonment.
See Chambers,
On direct appeal, Mr. Shipp submitted challenges to his conviction and sentence, arguing
inter alia
that (1) the district court erred by classifying his escape charge as a violent felony and by failing to submit to the jury the question of whether his escape crime was a “violent” offense, and (2) his escape crime did not involve actual or potential violence.
See United States v. Shipp,
Mr. Shipp filed a
pro se
petition for habeas relief under § 2255 on May 8, 2008, arguing ineffective assistance of counsel
*1087
that resulted in a sentence “imposed in excess of the maximum authorized by law.” Rec., vol. I at 25. As relevant here, he contended that “the sentencing judge erred in applying Tenth Circuit law and sentencing him as an armed career criminal for a walkaway escape conviction, when the Ninth Circuit does not treat this type of crime as a violent felony under the ACCA.”
United States v. Shipp,
The district court denied relief.
Id.
at 1320-21. Mr. Shipp filed a timely
pro se
petition for a COA, contending the ACCA enhancement gave rise to a “constitutional issue eoncern[ing] greater loss of liberty when he did not commit a prior crime of violence.” Jan. 1, 2009 Mot. for a COA, at 2. On January 13, 2009, the Supreme Court decided
Chambers,
holding that Illinois’s crime of failure to report for penal confinement fell outside the scope of the ACCA’s “violent felony” definition because the offense did not have “as an element the use, attempted use, or threatened use of physical force against the person of another.”
II.
We must first determine whether we have authority to review the issues raised by petitioner. Title 28 U.S.C. § 2253 governs our review of a district court’s denial of a habeas petition. Under § 2253, we must grant a COA to a habeas petitioner before he may proceed in our court. A COA may issue “only if the applicant has made a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2);
see Miller-El v. Cockrell,
The COA we previously issued is confined to the statutory issue of the retro-activity of
Chambers.
Nevertheless, circuit courts, including our own, have recognized that they possess the authority to expand the COA to cover uncertified, underlying constitutional claims asserted by an appellant.
See e.g., Adams,
Construing Mr. Shipp’s
pro se
pleadings liberally,
see Boag v. MacDougall,
Mr. Shipp’s offense of conviction, possession of a firearm after a felony conviction, carries a maximum statutory penalty of ten years.
See
18 U.S.C. § 924(a)(2). Under the ACCA, defendants qualifying as “armed career criminals” are subject to a mandatory minimum prison term of fifteen years.
See
§ 924(e)(1);
Chambers,
III.
With respect to Mr. Shipp’s statutory retroactivity claim, both parties re
*1089
fer us to
Teague v. Lane,
In contrast to Teague’s general bar on retroactivity of constitutional procedural rules to convictions that are already final, “[n]ew
substantive
rules generally apply retroactively. This includes decisions that narrow the scope of a criminal statute by interpreting its terms.”
Schriro v. Summerlin,
[i]n each of these cases, the courts determined that a new Supreme Court interpretation of a criminal statute, which narrowed the scope of the relevant crime, should be applied retroactively on collateral review. The courts relied on the new decisions to vacate the convictions, holding that the petitioners had been convicted for conduct Congress had never made criminal.
Id. at 994.
Whether
Teague
or
Davis
supplies the governing standard applicable to a particular case is not always clear. In fact the Court noted in
Schriro
that it has “sometimes referred to [substantive rules] ... as falling under an exception to
Teague’s
bar on retroactive application of procedural
*1090
rules; [even though] they are more accurately characterized as substantive rules not subject to the bar.”
The Teague doctrine is founded on the notion that one of the principal functions of habeas corpus is to assure that no man has been incarcerated under a procedure which creates an impermissibly large risk that the innocent will be convicted. Consequently, unless a new rule of criminal procedure is of such a nature that without it the likelihood of an accurate conviction is seriously diminished, there is no reason to apply the rule retroactively on habeas review. By contrast, decisions of this Court holding that a substantive federal criminal statute does not reach certain conduct, like decisions placing conduct beyond the power of the criminal law-making authority to proscribe, necessarily carry a significant risk that a defendant stands convicted of an act that the law does not make criminal.
Bousley,
As the government agrees,
Chambers
falls within the category of substantive decisions that “prohibit[] a certain category of punishment for a class of defendants because of their status or offense.”
Id.
Pursuant to the ACCA, Mr. Shipp was sentenced as an armed career criminal to a term of incarceration that exceeds the statutory maximum for the underlying offense of conviction.
Chambers’
construction of the ACCA overrules our prior jurisprudence attributing violence to escape offenses that did not involve the use, attempted use, or threat of the use of physical force against another.
See, e.g., Shipp I,
Given
Davis
and its progeny, we hold that the Supreme Court’s construction of the ACCA in
Chambers
applies retroactively to Mr. Shipp on collateral review. Accordingly, we REVERSE the district court’s denial of Mr. Shipp’s § 2255 petition. We REMAND the case to the district court with directions to correct Mr. Shipp’s sentence in light of
Chambers,
Notes
. In the district court, to the contrary, Mr. Shipp was entitled to habeas relief if he could show 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....” 28 U.S.C. § 2255 (emphasis added).
See Davis v. United States,
. As we have noted, the guideline range for Mr. Shipp’s underlying conviction for possession of a firearm after a former felony was twenty-seven to thirty-three months. Mr. Shipp was sentenced on Feb. 15, 2006, see rec., vol. II at 19; as of the date of this Order, he has served in excess of forty-four months in prison.
. As we said in
Weitz v. Lovelace Health System, Inc.,
