                         October 20, 1999

Before JONES, WIENER, and STEWART, Circuit Judges.

PER CURIAM:*

     Samuel Fiacro Pena, federal prisoner #50360-098, appeals the

dismissal of his application filed pursuant to 28 U.S.C. § 2241,

in which he argues that his counsel was ineffective for failing

to argue: (1) that he was not brought to trial within the time

limits imposed by the Speedy Trial Act, 18 U.S.C. §§ 3161-3174;

and (2) that the district court erroneously applied the

sentencing guidelines in imposing his sentence.

     *
        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that this opinion should not be published and is not precedent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.
                           No. 99-50607
                                -2-

     Each of these claims addresses alleged errors that occurred

prior to or during Pena’s conviction and sentence.    Therefore, he

may raise them in a § 2241 petition only if he can demonstrate

that a motion filed under § 2255 would not provide an adequate

and effective means of challenging the legitimacy of his

detention.   See Cox v. Warden, Fed. Detention Ctr., 911 F.2d

1111, 1113 (5th Cir. 1990).   Pena has failed make such a showing;

the mere fact that his prior § 2255 motion raising these claims

was denied is itself insufficient.   See Lane v. Hanberry, 601

F.2d 805, 807 (5th Cir. 1979).

     In this action, Pena has merely refiled his prior § 2241

motion in the hope of obtaining a different result.   This appeal

is therefore frivolous, and will be dismissed as such.   We thus

warn Pena that the filing of further frivolous or repetitious

motions for authorization may invite the imposition of sanctions.

     APPEAL DISMISSED; SANCTIONS WARNING ISSUED.
