This appeal challenges only the sentence imposed after a plea of guilty to drug distribution charges. After evidentiary hearing, the court concluded that defendant was at “least a supervisor or a manager” and imposed a corresponding enhancement factor pursuant to United States Sentencing Commission, Guidelines Manual, § 3Bl.l(c) (Nov.1989) (“Guide lines”). Record, vol. 3, at 27. Defendant makes a three-fold attack on the application of section 3Bl.l(c) in determining his sentence.
Defendant first challenges the sufficiency of the evidence. Because that issue is primarily factual, we apply a clearly erroneous standard.
See
18 U.S.C. § 3742(e) (1988);
United States v. Roberts,
Defendant’s second challenge is to the conclusion that his activities legally qualify him as a supervisor as defined in the
Guidelines.
Because this issue is primarily legal, we review the district court under a
de novo
standard.
See Roberts,
Finally, defendant argues that the language of section 3Bl.l(c) is unconstitutionally vague. A standard is only unconstitutionally vague if it is not “sufficiently explicit to inform those who are subject to it what conduct on their part will render them liable to its penalties.”
Connally v. General Const. Co.,
We reject all of defendant’s challenges to his sentence, and we AFFIRM the judgment and sentence of the trial court.
