               ORDER DENYING CERTIFICATE OF APPEALABILITY *


Before O’BRIEN, McKAY, and TYMKOVICH, Circuit Judges.



      Petitioner, a state prisoner proceeding pro se, seeks a certificate of

appealability to appeal the district court’s denial of his § 2241 habeas petition.

Petitioner was convicted of burglary in the second degree and sentenced to a

twenty-year split sentence with ten years suspended. He began serving the

incarceration portion in March 2004 and completed this portion in June 2008 due

to good-time credits. The expiration date of Petitioner’s sentence remains as

December 1, 2023 (calculated from the sentencing date of December 2, 2003, plus



      *
        This order is not binding precedent except under the doctrines of law of
the case, res judicata, and collateral estoppel. It may be cited, however, for its
persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
the length of the twenty-year sentence minus one day). Petitioner filed this

habeas petition arguing that his overall sentence should be reduced according to

the credits applied to his period of incarceration. The magistrate judge

recommended dismissal of Petitioner’s claims, and, after conducting a de novo

review, the district court agreed with the magistrate judge that Petitioner was

asserting a state law claim and not a violation of a federal constitutional right.

The district court therefore dismissed Petitioner’s claims and denied a certificate

of appealability.

      To appeal the denial of his habeas petition, Petitioner must first obtain a

certificate of appealability. See 28 U.S.C. § 2253(c)(1); Montez v. McKenna, 

, 869 (10th Cir. 2000). We cannot issue a COA unless the applicant

makes “a substantial showing of the denial of a constitutional right.” 28 U.S.C. §

2253(c)(2). We agree with the district court that Petitioner has not identified a

violation of any federal constitutional right. Oklahoma courts have rejected

Petitioner’s argument that the Department of Corrections’ application of good-

time credits should reduce his overall sentence. See Hemphill v. State, 

, 151 (Okla. Crim. App. 1998) (“[Department of Corrections] sentence

calculations do not result in modification of the length of time a district court has

fixed for the expiration of a defendant’s suspended sentence.”). “A state court’s

interpretation of its own law is binding on a federal court conducting habeas

review.” House v. Hatch, 

, 1028 (10th Cir. 2008).

                                         -2-
      The district court appropriately applied this principle. After carefully

reviewing Petitioner’s brief and the record on appeal, we conclude that reasonable

jurists would not debate whether the district court erred in dismissing the petition.

See Slack v. McDaniel, 

, 484 (2000). We therefore DENY the

application for a certificate of appealability and DISMISS the appeal.

Petitioner’s motion to proceed in forma pauperis on appeal is DENIED.
