ORDER DENYING CERTIFICATE OF APPEALABILITY *

Petitioner, a state prisoner proceeding pro se, seeks a certifícate of appealability to appeal the district court’s denial of his § 2254 habeas petition. In the state court proceedings, Petitioner was convicted of manslaughter and sentenced to twenty-nine years’ imprisonment. He filed an appeal with the Oklahoma Court of Criminal Appeals in which he argued, inter alia, that he received ineffective assistance of counsel at sentencing and that “the trial court’s erroneous decisions [at sentencing] were an abuse of discretion which denied Mr. Terrill’s right to due process and a fair [ ]sentencing hearing under the Fifth and Fourteenth Amendments to the United States Constitution.” (R. at 56.) The Oklahoma Court of Criminal Appeals rejected these arguments and affirmed the conviction and twenty-nine-year sentence. 1

Petitioner then filed the instant habeas petition, in which he again raised claims of ineffective assistance and trial court errors in the sentencing proceeding. The district court denied the petition, holding that the Oklahoma Court of Criminal Appeals’ rejection of Petitioner’s ineffective assistance claim was not contrary to or an unreasonable application of clearly established federal law and that Petitioner’s claims of error in the sentencing proceeding did not state a valid federal claim for relief. See Dennis v. Poppel, 222 F.3d 1245, 1258 (10th Cir. 2000) (“[C]hallenges to [the state trial court’s sentencing] decision are not generally constitutionally cognizable, unless it is shown the sentence imposed is outside the statutory limits or unauthorized by law.”).

In his request for a certificate of appeal-ability, Petitioner argues the district court erroneously treated Petitioner’s sentencing claim as a matter of state law and failed to consider his constitutional due process arguments. We have thoroughly considered Petitioner’s due process arguments and conclude that reasonable jurists would not debate the district court’s determination that there was no constitutionally cognizable error in the sentencing proceeding. See Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000). We likewise conclude that reasonable jurists would not debate the district court’s resolution of Petitioner’s ineffective assistance claim. Therefore, for substantially the same reasons given by the district court, we DENY Petitioner’s request for a certificate of appealability and DISMISS the appeal. Petitioner’s motion to proceed in forma pauperis on appeal is GRANTED.
