Respondent has filed a motion to vacate the stay of execution entered by the district court. The grounds on which the stay was granted include a threshold jurisdictional question under the Antiterrorism
*1303
and Effective Death Penalty Act (“AED-PA”), the resolution of which may require an evidentiary hearing.
See
Dist. Ct. Order at 15 (“[T]here may be ... claims that carry the potential to invoke equitable tolling. Without proper briefing, perhaps a hearing, and sufficient opportunity to contemplate the various claims and their implications vis-a-vis the limitations period, the court cannot permit the execution to go forward.”). Under these circumstances, we do not find that the district court has abused its discretion.
See Hauser v. Moore,
Notes
. While neither party has raised the issue of whether we have subject matter jurisdiction over this case, we are obliged to address the issue
sua sponte. See Rembert v. Apfel,
The question thus presented is whether the state is required to obtain a COA before appealing, and if so, whether a COA is required on interlocutory appeal. Prior to the passage of AEDPA, § 2253 required that a petitioner for habeas relief obtain a certificate of probable cause (“CPC”). Under that provision, this circuit held "that it is not necessary for a state or its representative to obtain a [CPC] in order to take an appeal to the Court of Appeals from a final order granting a writ.”
