    UNITED STATES of America, Plaintiff-Appellee, v. Michael Earl HILL, Defendant-Appellant.
    No. 05-11129
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Oct. 13, 2006.
    Michael Earl Hill, Seagoville, TX, pro se.
    Before REAVLEY, GARZA and BENAVIDES, Circuit Judges.
   PER CURIAM:

Michael Earl Hill, federal prisoner #27877-177, appeals the district court’s denial of his Fed.R.Civ.P. 60(b)(4) motion for relief from judgment. Following his guilty plea to one count of securities fraud and one count of mail fraud, Hill was sentenced to a term of imprisonment of 60 months on each count, to be served consecutively and to be followed by a three-year term of supervised release.

Hill argues that, in light of Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), and United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), his sentence was unconstitutionally enhanced, that the enhancement of his sentence caused a structural error in his sentencing hearing, and that the district court lacked jurisdiction to enhance Hill’s sentence. Because Hill is challenging the validity of his underlying sentence, his Fed.R.CivP. 60(b)(4) motion should have been construed as a successive 28 U.S.C. § 2255 motion. See Fierro v. Johnson, 197 F.3d 147, 151 (5th Cir.1999); cf. Gonzalez v. Crosby, 545 U.S. 524, 125 S.Ct. 2641, 2651, 162 L.Ed.2d 480 (2005). Prior to filing the successive motion, Hill was required to obtain authorization to file the successive motion. See 28 U.S.C. §§ 2244(b)(3)(A), 2255. Because Hill failed to obtain such authorization, the district court did not err in denying the motion. See Scott v. Johnson, 227 F.3d 260, 262 (5th Cir.2000).

AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
