Eric Creighton Sampson petitions for a writ of mandamus seeking an order clarifying the court’s opinion in his direct appeal and remanding his case to the district court. See United States v. Sampson, 140 F.3d 585 (4th Cir. 1998). We conclude that Sampson is not entitled to mandamus relief.

Mandamus relief is available only when the petitioner has a clear right to the relief sought. In re First Fed. Sav. & Loan Ass’n, 860 F.2d 135, 138 (4th Cir. 1988). Further, mandamus is a drastic remedy and should only be used in extraordinary circumstances. Kerr v. United States Dist. Court, 426 U.S. 394, 402, 96 S.Ct. 2119, 48 L.Ed.2d 725 (1976); In re Beard, 811 F.2d 818, 826 (4th Cir. 1987). Mandamus may not be used as a substitute for appeal. In re United Steelworkers, 595 F.2d 958, 960 (4th Cir. 1979).

The relief sought by Sampson is not available by way of mandamus. Accordingly, although we grant leave to proceed in forma pauperis, we deny the petition for writ of mandamus. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

PETITION DENIED.
