TENTH CIRCUIT

JAMES ROBINSON,

Petitioner - Appellant,

vs.

UNITED STATES OF AMERICA,

Respondent - Appellee.

No. 99-3172

(	D.C. No. 99-3169-RDR)

(D. Kan.)

ORDER AND JUDGMENT*

Before ANDERSON, KELLY, and BRISCOE, Circuit Judges.**

Mr. Robinson, an inmate appearing pro se, appeals from the district court's judgment dismissing his habeas petition, 28 U.S.C. § 2241, without prejudice. On appeal, he argues that his conviction was invalid for lack of jurisdiction and that the government withheld exculpatory evidence. Of course, the validity of his conviction must be challenged in a § 2255 motion; a § 2241 petition goes to the execution of the sentence. Only if the opportunity to challenge the validity of the conviction is "inadequate or ineffective" under § 2255 may relief be sought under § 2241. See Bradshaw v. Story, 86 F.3d 164, 166 (10th Cir. 1996). Mr. Robinson argues that his opportunity to challenge his conviction under § 2255 was ineffective because he was denied a certificate of appealability. Failure to obtain relief on a previous § 2255 motion does not make that remedy inadequate or ineffective. Id. Accordingly, Mr. Robinson's claims are not proper under § 2241, and the district court properly dismissed the petition.

AFFIRMED.
