governed issuance of the pre-AEDPA version of the COA, the certifícate of probable cause (“CPC”), apply to requests for a COA. See id. at 756.
The post-AEDPA version of 28 U.S.C. § 2254(d) provides as follows:
(d) An application for a writ of habeas corpus on behalf of a person in custody pursuant to the judgment of a State court shall not be granted with respect to any claim that was adjudicated on the merits in State court proceedings unless the adjudication of the claim—
(1) resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States; or
(2) resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.
28 U.S.C. § 2254(d). We review pure questions of law under the “contrary to” standard of subsection (d)(1), mixed question of law and fact under the “unreasonable application” standard of subsection (d)(1), and pure questions of fact under the “unreasonable determination of facts” standard of subsection (d)(2). See Lamb v. Johnson, 179 F.Bd 352, 356 (5th Cir.1999) (citing Drinkard, 97 F.3d at 767-69), cert. denied, — U.S. -, 120 S.Ct. 522, 145 L.Ed.2d 401 (1999).
An application of law to facts will not be deemed unreasonable, unless reasonable jurists “would be of one view that the state court ruling was incorrect.” Drinkard, 97 F.3d at 769. And under this standard, we will grant habeas relief “only if a state court decision is so clearly incorrect that it would not be debatable among reasonable jurists.” Id. Additionally, under § 2254(e)(1), a state court’s determination of a factual issue must be presumed correct, and the habeas petitioner bears the burden of rebutting the presumption by clear and convincing evidence. The presumption is especially strong when the state habeas court and the trial court are one in the same. See Amos v. Scott, 61 F.3d 333, 347 (5th Cir.1995); James v. Collins, 987 F.2d 1116, 1122 (5th Cir.1993) (citing Buxton v. Lynaugh, 879 F.2d 140, 146 (5th Cir.1989)).
And while the nature of the penalty in a capital case is an appropriate consideration for determining whether to issue a COA, the severity of the penalty at issue does not, in and of itself, require the issuance of a COA. See Lamb, 179 F.3d at 356. However, in capital cases, doubts as to whether a COA should issue must be resolved in favor of the petitioner. See id.; see also Buxton v. Collins, 925 F.2d 816, 819 (5th Cir.1991). Bearing the foregoing principles in mind, we turn to consider those issues raised by Clark in his request for a COA.
A.
Clark first contends that he is entitled to a COA on the basis that summary judgment is not contemplated by 28 U.S.C. § 2254 or the Rules Governing § 2254 Cases. He contends that the Texas Attorney General cited no cases, statutes, or rules in the original motion for summary judgment which hold that summary judgment is appropriate in § 2254 cases. Yet in his own briefings, Clark cites no authority for the opposite proposition.
As a general principle, Rule 56 of the Federal Rules of Civil Procedure, relating to summary judgment, applies with equal force in the context of habeas corpus cases. See Rule 11 of the Rules Governing § 2254 Cases; Fed.R.Civ.P. 81(a)(2). We have previously recognized the appropriateness of summary judgment in habeas corpus proceedings. See e.g., Barnes v. Johnson, 160 F.3d 218, 222 (5th Cir.1998), cert. denied, — U.S.-, 119 S.Ct. 1768, 143 L.Ed.2d 798 (1999); Harris v. Johnson, 81 F.3d 535, 539 (5th Cir.1996) (both applying summary judgment standard in a § 2254 case). And nothing in Clark’s briefing convinces us that summary judg
