Opinion for the Court filed by Senior Circuit Judge WILLIAMS.
A prisoner convicted in D.C. Superior Court may raise a collateral challenge to his sentence by motion in that court, D.C.Code § 23-110(a), but may not apply for a writ of habeas corpus “unless it ... appears that the remedy by motion is inadequate or ineffective to test the legality of his detention,”
id.
§ 23 — 110(g). Because the Supreme Court has found that the District of Columbia judges’ lack of life tenure and constitutional salary protection do not render the § 23-110 remedy “inadequate or ineffective,” see
Swain v. Pressley,
In
Williams v. Martinez,
As a result of multiple convictions, appellant Jibril L. Ibrahim (a.k.a. Grant Anderson) is serving an aggregate life sentence imposed by the D.C. Superior Court and affirmed by the DCCA. He has often challenged these convictions in D.C. and federal courts. On October 23, 2008 he filed a petition for writ of habeas corpus in the district court for the District of Columbia, “based on actual innocence coupled with a constitutional violation and miscarriage of justice claims ... and other due process and equal protection of law claims.” Appendix for Amicus/Appellant (“App.”) 6. The district court dismissed the petition for want of jurisdiction, reasoning that Ibrahim was required to pursue his challenge in D.C. Superior Court rather than federal court because his § 23-110 remedy was not inadequate or ineffective.
Ibrahim v. United States,
No. 08-cv-2130,
Under 28 U.S.C. § 2253(c)(1), an appeal can be taken from a habeas corpus or § 2255 рroceeding before a district court only if a certificate of appealability (“COA”) is issued by a circuit justice, or a circuit or district judge. See
United States v. Mitchell,
The district court denied Ibrahim’s initial request for a COA. See Notice to Court of Appeals (July 7, 2009), App. 23. Ibrahim applied to this court for a COA on July 29, 2009, and we held the application in abeyance pending our decision in
Williams.
We then appointed amicus curiae to address whether our holding in
Williams
had any bearing on Ibrahim’s effort to pursue his claims in federal court. Through able amicus, Ibrahim now argues that the district court had jurisdiction to hear his petition under 28 U.S.C. § 2254 on the theory that, as with the appellаnt in
Williams,
a prior DCCA decision — in Ibrahim’s case
Diamen v. United States,
As we explain below, we conclude that jurists of reason would not find his claim that the district court had jurisdiction “debatable.” In essence this is because Diamen cannot reasonably be read to bar Ibrahim from bringing his federal constitutional claims in D.C. Superior Court under § 23-110. Aсcordingly we deny the COA.

Section 23 — 110(a)(1) allows a D.C. prisoner to challenge his sentence “upon the ground that ... the sentence was imposed in violation of the Constitution of the United States.” Although the exact nature of Ibrahim’s constitutional claims is not clear, they involve “actual innocence coupled with a constitutional violation and miscarriage of justice” and “other due process and equal protection of law claims.” Amicus’s Br. 7; App. 6. The reason Ibrahim provides for not being able to bring these constitutional claims under § 23-110(a) is that “his actual innocence allegations are tethered to alleged constitutional violations,” Amicus’s Br. 13, and accordingly, in light of Diamen, the IPA “provides the exclusive judicial remedy for District of Columbia offenders who ... obtain new evidence of actual innocence more than three years after they are convicted,” see id. at 19-20. This is, quite simply, a misreading of Diamen.
There are theoretically two recognized types of constitutional claims for which newly discovered evidence of actual innocence has been found relevant: “standalone” innocence claims associated with
Herrera v. Collins,
In Diamen, as here, the appellants sought to vacate their convictions based on newly discovered evidence demonstrating actual innocence and constitutional errors committed at trial. See Diamen, 12S> A.2d at 503-04. Their claims were brought by motion under § 23-110. See id. The DCCA divided its discussion into two segments: “II: Newly Discovered Evidence and the Claim of Actual Innocence,” largely revolving around the Supreme Court’s decision in Herrera, and “HI: The Alleged Cоnstitutional Violation,” largely revolving around Schlup. We follow Diamen in using those two categories to analyze the decision’s meaning.

Herrera.
As to claims along the lines of
Herrera,
the
Diamen
court held that such claims were barred by Rule 33 of the Superior Court’s Rules of Criminal Procedure, which required them to be brought within two years of the verdict. See
Diamen,
The
Diamen
court additionally concluded that applying Rule 33’s two-year limit to the claims did not hinder the appellants’ federal constitutional rights under
Herrera.
In that case, the Supreme Court “assume[d],” without deciding, “that in a capital case a truly persuasive demonstration of ‘actual innocence’ made after trial would render the execution of a defendant unconstitutional, and warrant federal habeas relief if there were no state avenue open to process such a claim.”
Although Ibrahim’s position on whether he is even bringing a Herrera-type claim is rather muddled, and the record is not developed enough to be sure of the exact dimensions of any such claim, Diamen cannot reasonably be read to bar a Hemra type claim from being brought under § 23-110.
To counter Diamen’s careful effort to conform to Herrera itself, Ibrahim points to the following language from Diamen’s conclusion:
One who reads Super. Ct. Crim. R. 33 in conjunction with the Supreme Court’s decision in Herrera is led to the uncomfortable sense that an innocent defendant may be executed or left to rot in jail because conclusive exculpatory evi *1145 dence, through no fault of his own, came to his attention too late. Such a defendant is, of course, free to apply for executive clemency, but pardons are discretionary, and often politically unpopular as well. Moreover, a defendant cannot fairly be blаmed if he regards executive clemency as an insufficient remedy when he did not in fact commit the crime for which he is being pardoned. An innocent man asks for justice, not for mercy.... Under Rule 33 as written, however, passage of a relatively short time — two years — acts as an absolutе bar, no matter how compelling the showing of innocence may be.
Amicus’s Reply Br. 11-12 n.6 (quoting
Di-amen,
Schlup.
The
Diamen
court found that
Schlup
was not “contrary to [its] analysis.”
The district court’s decision in
Eastridge v. United States,
Ibrahim argues that § 23-110 is inadequate and ineffеctive as to his “gateway” claims for an additional reason. He contends that
Diamen
interpreted
Schlup
more narrowly than have some federal district courts that have regarded the “fundamental miscarriage of justice” exception to procedurally barred constitutional claims as applicable even when there is no direct
*1146
nexus between newly discovered evidence and the claims. See Amicus’s Br. 28 n.21 (citing
United States v. Roman,
First, the entire discussion of a necessary relation between the new evidence and the constitutional error was dictum, because, as we’ve already noted, the Dia
men
court’s decision ultimately rested on the failure of the newly disсovered evidence in question to meet “the substantive standard articulated in
Schlup
and in the authorities on which
Schlup
relies.”
Id.
at 512. In other words, the appellants had a poor
Schlup
claim, not one that could not be brought at all.
Second,
even if
Diamen
had interpreted an unresolved aspect of
Schlup
somewhat more narrowly than one or more district courts, any such divergence of opinion would not take the constitutional claim “outside [§ 23-110’s] scope,”
Williams,
Finаlly, Ibrahim argues that a D.C. prisoner can pursue a Schlup-based habeas claim in federal district court
regardless
of whether the claim can be pursued under § 23-110. Under this theory, § 23-110(g)
itself
constitutes a “procedural bar” as envisioned in
Schlup,
see
But § 23-110(g) is not a procedural bar to otherwise available federal habeas claims; it is Congress’s deliberate channeling of constitutional collateral attacks on Superior Court sentences to courts within the District’s judicial system (subject to Supreme Court review), with federal habeas available only as a safety valve. If Bonilla’s interpretation were correct, it would read § 23-110(g) out of the statute as applied to Schlup claims. That is not a reasonably debatable construction.
We thus conclude that the § 23-110 remedy is neither inadequate nor ineffective to test the legality of Ibrahim’s claims. Accordingly § 23-110(g) presented the sort of “plain procedural bar” that justifies dismissal of the case.
