*705 Yesenia Leal, federal prisoner # 92524-079, appeals the district court’s denial of her motion to compel the Government to file a motion for reduction of sentence pursuant to Fed.R.CeimP. 35(b).

Rule 35(b) does not provide a jurisdictional basis upon which to entertain Leal’s motion. See United States v. Early, 27 F.3d 140, 141-42 (5th Cir. 1994). The Government’s refusal to file a Rule 35 motion is reviewable only if it is based on an unconstitutional motive, which Leal does not allege. See United States v. Sneed, 63 F.3d 381, 389 n. 6 (5th Cir. 1995). Leal’s motion is thus unauthorized and the district court and this court both lack jurisdiction to consider it. Accordingly, the appeal is DISMISSED for lack of jurisdiction.
