*521Respondent Edward Schad was convicted of first-degree murder and sentenced to death. After an extensive series of state- and federal-court proceedings concluded with this Court's denial of respondent's petitions for certiorari and for rehearing, the Ninth Circuit declined to issue its mandate as normally required by Federal Rule of Appellate Procedure 41(d)(2)(D). The Ninth Circuit instead, sua sponte, construed respondent's motion to stay the mandate pending the Ninth Circuit's decision in a separate en banc case as a motion to reconsider a motion that it had denied six months earlier. Based on its review of that previously rejected motion, the court issued a stay a few days before respondent's scheduled execution. Even assuming, as we did in Bell v. Thompson,

In 1985, an Arizona jury found respondent guilty of first-degree murder for the 1978 strangling of 74-year-old Lorimer Grove.
In August 1998, respondent sought federal habeas relief. He again raised a claim of ineffective assistance at sentencing for failure to present sufficient mitigating evidence. The District Court denied respondent's request for an evidentiary hearing to present new mitigating evidence, concluding that respondent was not diligent in developing the evidence during his state habeas proceedings. Schad v. Schriro,
On July 10, 2012, respondent filed in the Ninth Circuit the first motion directly at issue in this case. This motion asked the court to vacate its judgment and remand to the District Court for additional proceedings in light of this Court's decision in *2550Martinez v. Ryan,
Respondent returned to the Ninth Circuit that day and filed a motion requesting a stay of the mandate in light of a pending Ninth Circuit en banc case addressing the interaction between Pinholster and Martinez . The Ninth Circuit denied the motion on February 1, 2013, "declin[ing] to issue an indefinite stay of the mandate that would unduly interfere with Arizona's execution process." Order in No. 07-99005, Doc. 102, p. 1. But instead of issuing the mandate, the court decided sua sponte to construe respondent's motion "as a motion to reconsider our prior denial of his Motion to Vacate *524Judgment and Remand in light of Martinez, " which the court had denied on July 27, 2012. Id., at 2. The court ordered briefing and, in a divided opinion, remanded the case to the District Court to determine whether respondent could establish that he received ineffective assistance of postconviction counsel under Martinez, whether he could demonstrate prejudice as a result, and whether his underlying claim of ineffective assistance of trial counsel had merit. No. 07-99005 (Feb. 26, 2013), App. to Pet. for Cert. A-13 to A-15,
On March 4, 2013, Arizona filed a petition for rehearing and rehearing en banc with the Ninth Circuit. The court denied the petition the same day, with eight judges dissenting in two separate opinions.
On March 4, Arizona filed an application to vacate the stay of execution in this Court, along with a petition for certiorari. This Court denied the application, with Justices SCALIA and ALITO noting that they would grant it. 568 U.S. ----,

Federal Rule of Appellate Procedure 41(d)(2)(D) sets forth the default rule that "[t]he court of appeals must issue the mandate immediately when a copy of a Supreme Court order denying the petition for writ of certiorari is filed." (Emphasis added.) The reason for this Rule is straightforward: "[T]he stay of mandate is entered solely to allow this Court time to consider a petition for certiorari." Bell,
Bell recognized that when state-court judgments are reviewed in federal habeas proceedings, "finality and comity concerns," based in principles of federalism, demand that federal courts "accord the appropriate level of respect to" state judgments by allowing them to be enforced when federal proceedings conclude.
Applying this standard in Bell, we found no extraordinary circumstances that could constitute a miscarriage of justice.
*526There, a capital defendant unsuccessfully alleged in state postconviction proceedings that his trial counsel had been ineffective by failing to introduce sufficient mitigating evidence in the penalty phase of trial.
When this Court denied the petition for rehearing, the Sixth Circuit did not issue its mandate. Instead, the Sixth Circuit waited five months (and until two days before the scheduled execution) to issue an amended opinion that vacated the District Court's denial of habeas and remanded for an evidentiary hearing on the ineffective-assistance-of-counsel claim.
In this case, the Ninth Circuit similarly abused its discretion when it did not issue the mandate. As in Bell, the Ninth Circuit here declined to issue the mandate based on an argument it had considered and rejected months earlier. And, by the time of the Ninth Circuit's February 1, 2013, decision not to issue its mandate, it had been over 10 months since we decided Martinez and nearly 7 months since respondent *2552unsuccessfully asked the Ninth Circuit to reconsider its decision in light of Martinez .
Finally, this case presents an additional issue not present in Bell . In refusing to issue the mandate, the Ninth Circuit panel relied heavily upon Beardslee v. Brown,
In light of the foregoing, we hold that the Ninth Circuit abused its discretion when it neglected to issue its mandate. The petition for a writ of certiorari and respondent's motion to proceed in forma pauperis are granted. The Ninth Circuit's judgment is reversed, the stay of execution is vacated, and the case is remanded with instructions to issue the mandate immediately and without any further proceedings.
It is so ordered .
Notes
A state habeas court vacated an earlier guilty verdict and death sentence due to an error in jury instructions. See State v. Schad,
Martinez,
Respondent did not even present the motion that the Ninth Circuit ultimately reinstated until more than 4 months after the Ninth Circuit denied respondent's request for panel rehearing and rehearing en banc and more than 3 ½ months after Martinez was decided.
