    James Joseph OWENS-EL, Petitioner-Appellant, v. Warden WILEY; U.S. Parole and Probation Conglomerate, Respondent-Appellee.
    No. 05-1423.
    United States Court of Appeals, Tenth Circuit.
    May 30, 2006.
    James Joseph Owens-El, Florence, CO, pro se.
    William J. Leone, John M. Hutchins, Office of the United States Attorney, Denver, CO, for Respondent-Appellee.
    Before HARTZ, EBEL, and TYMKOVICH, Circuit Judges.
   ORDER AND JUDGMENT

HARRIS L. HARTZ, Circuit Judge.

James Joseph Owens-El, a federal prisoner at the United States Penitentiary in Florence, Colorado, appeals the dismissal by the United States District Court for the District of Colorado of his application for a writ of habeas corpus under 28 U.S.C. § 2241. We review the dismissal of an application under § 2241 de novo. See Bradshaw v. Story, 86 F.3d 164, 166 (10th Cir.1996). We have jurisdiction under 28 U.S.C. § 1291 and afSrm the judgment of the district court.

In his expansive, nearly incomprehensible, briefs to this court, Mr. Owens-El appears to challenge his federal sentence because it was imposed, at least in part, in consideration of a Maryland state-court conviction he received in 1968 as a juvenile tried as an adult. Mr. Owens-El claims that the 1968 conviction was expunged from his record in 1997 as unconstitutional under Woodall v. Pettibone, 465 F.2d 49 (4th Cir.1972). This claim constitutes an attack on the validity of his federal sentence, cognizable under 28 U.S.C. § 2255, rather than an attack on the execution of his sentence, which would fall within the scope of applications under § 2241.

Because § 2255 requires that a motion thereunder be filed in the sentencing court, and Mr. Owens-El was sentenced by the Central District of California rather than the District of Colorado, the district court lacked jurisdiction to consider his application when properly construed as a motion under § 2255. Therefore, we AFFIRM the district court’s dismissal of his application. See Owens-El v. Hood, 117 Fed.Appx. 35, 36 (10th Cir.2004); cf. Owens-El v. Surgure, 66 Fed.Appx. 181 (10th Cir.2003).

Also before us are Mr. Owens-El’s motion seeking a writ of mandamus from this court, filed May 4, 2006, and several other filings related to “Newly Developed Evidence” and “New Facts.” Because we fail to discern what, if any, action he seeks from this court, the motion is DENIED. To the extent that the other filings seek relief, they relate to the claims in the § 2241 petition and are similarly DISMISSED as not cognizable under that statute. 
      
       After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. The court generally disfavors the citation of orders and judgments; nevertheless, an order and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
