                 Appeal from the United States District Court
                    for the Southern District of Alabama
                       _________________________

                              (July 7, 2005)

Before CARNES, BARKETT and MARCUS, Circuit Judges.

PER CURIAM:

     Adrian LeMoyne Lacey, a federal prisoner serving a 63-month sentence for
possession with intent to distribute cocaine, in violation of 21 U.S.C. § 841(a)(1),

appeals pro se the denial of his post-judgment motion to compel the government to

file a Rule 35(b) motion for reduction of his sentence. On appeal, Lacey argues

that the government breached his plea agreement by refusing to file a motion

pursuant to Rule 35 of the Federal Rules of Criminal Procedure to reduce his

sentence after he allegedly offered the government substantial assistance in the

apprehension of a fugitive. Lacey claims that the government refused to file the

motion because of his race.1 We find no error, and affirm his sentence.

       Although the government argues that Lacey waived the right to collaterally

attack his sentence when he entered into the plea agreement, we have previously

considered appeals alleging government breach of a plea agreement despite appeal

waivers. See United States v. Copeland, 381 F.3d 1101, 1105 (11th Cir. 2004).

Thus, we conclude that we may consider this appeal.

       We review de novo whether the district court can compel the government to

make a substantial assistance motion. See United States v. Forney, 9 F.3d 1492,

1498 (11th Cir. 1993). The question whether the government has breached a plea

agreement is also subject to de novo review. United States v. Mahique, 150 F.3d



       1
          Nine days after the government filed its brief in this appeal, Lacey filed a motion for
leave to supplement his brief. Because this motion was filed within the 14-day time limit for
filing a reply brief, we have construed his motion as a reply brief. See Fed.R.App.P. 31(a)(1).

                                                 2
1330, 1332 (11th Cir. 1998). After a defendant has been sentenced, Rule 35(b)

permits the district court, upon motion of the government, to reduce the sentence

for substantial assistance. Fed.R.Crim.P. 35(b). The government has “‘a power,

not a duty, to file a motion when a defendant has substantially assisted.’” Forney, 9

F.3d at 1500 (quoting Wade v. United States, 504 U.S. 181, 185 (1992)). In Wade,

the Supreme Court held that “federal district courts have authority to review a

prosecutor’s refusal to file a substantial-assistance motion and to grant a remedy if

they find that the refusal was based on an unconstitutional motive,” such as in a

case where the refusal was “because of the defendant’s race or religion.” Wade,

504 U.S. at 185-86. A defendant must make not only an allegation, but also a

“substantial showing” that the refusal was based on such constitutionally

impermissible grounds. Forney, 9 F.3d at 1502.

      We find that Lacey failed to make a substantial showing of unconstitutional

motive. Lacey alleges that he provided the government with substantial assistance

and the government refused to file a Rule 35 motion because he is African-

American. In support of this argument, he claims that the prosecutor who handled

his case had discriminated against three other African-American defendants, and

that a similarly situated white defendant had received a downward departure based

on substantial assistance. The allegations of discrimination were conclusory and



                                          3
unsubstantiated. Furthermore, unlike the white defendant, Lacey had failed a

polygraph test.2 Thus, Lacey and the white defendant were not similarly situated.

       We also find no breach of the plea agreement, which gave the government

the discretion to decide whether or not to file a substantial assistance motion. In

this case, the district court found that the government had refused to file the motion

because Lacey failed the polygraph examination. The government was not

required to file a substantial assistance motion, and acted within its discretion in

refusing to file the motion on these grounds.

       Because we find no reversible error, we affirm Lacey’s sentence.



       AFFIRMED.




       2
        The terms of Lacey’s plea agreement required Lacey to submit to the polygraph
examination, which sought to determine whether Lacey had information regarding the shooting
death of his pregnant girlfriend.
