Mario S. Sibug, Appellant Pro Se. Edward John Kelley, OFFICE OF
THE ATTORNEY GENERAL OF MARYLAND, Baltimore, Maryland, for
Appellees.

PER CURIAM:

            Mario S. Sibug seeks to appeal the district court’s

order     dismissing       as   untimely       his    28   U.S.C.       § 2254     (2006)

petition.     The order is not appealable unless a circuit justice

or judge issues a certificate of appealability.                         See 28 U.S.C.

§ 2253(c)(1)(A) (2006).           A certificate of appealability will not

issue     absent     “a     substantial    showing         of    the    denial     of    a

constitutional right.”           28 U.S.C. § 2253(c)(2) (2006).                  When the

district court denies relief on the merits, a prisoner satisfies

this    standard     by    demonstrating       that   reasonable        jurists     would

find that the district court’s assessment of the constitutional

claims is debatable or wrong.              Slack v. McDaniel, 

,

484    (2000);     see    Miller-El   v.   Cockrell,       

,     336-38

(2003).     When the district court denies relief on procedural

grounds, the prisoner must demonstrate both that the dispositive

procedural ruling is debatable, and that the petition states a

debatable claim of the denial of a constitutional right.                           Slack,

529 U.S. at 484-85.

            We have independently reviewed the record and conclude

that Sibug has not made the requisite showing.                         Accordingly, we

deny a certificate of appealability and dismiss the appeal.                             We

dispense     with        oral   argument   because         the    facts    and      legal




                                           2
contentions are adequately presented in the materials before the

court and argument would not aid the decisional process.



                                                           DISMISSED
