As to Petitioner’s first two requests—to compel the immediate grant of the Government’s motion, and to vacate the District Court’s appointment of amicus—Petitioner has not established that he has “no other adequate means to attain the relief he desires.” Cheney v. U.S. Dist. Court for D.C., 542 U.S. 367, 380 (2004) (quoting Kerr v. U.S. Dist. Court for N. Dist. of Cal., 426 U.S. 394, 403 (1976)). We also decline to mandate that the case be reassigned to a different district judge, because Petitioner has not established a clear and indisputable right to reassignment. See id. at 381. We therefore deny the Petition.
Under governing law, the writ of mandamus should issue only if: (1) “the party seeking issuance of the writ [has] no other adequate means to attain the relief he desires”; (2) “the petitioner [satisfies] the burden of showing that his right to issuance of the writ is clear and indisputable”; and (3) “the issuing court, in the exercise of its discretion, [is] satisfied that the writ is appropriate under the circumstances.” Cheney, 542 U.S. at 380–81 (citations, alterations, and internal quotation marks omitted). All three requirements must be satisfied, and the absence of any one compels denial of the writ. “As this case implicates the separation of powers, the Court of Appeals must also ask, as part of this inquiry, whether the District Court’s actions constituted an unwarranted impairment of another branch in the performance of its constitutional duties.” Cheney, 542 U.S. at 390.
Here, Petitioner and the Government have an adequate alternate means of relief with respect to both the Rule 48(a) motion and the appointment of amicus: the District Court could grant the motion, reject amicus’s arguments, and dismiss the case. At oral argument, the District Judge’s Attorney effectively represented that all these things may happen. See Oral Arg. Transcript at 122:24–25, 123:1–9. Even if the District Court were to deny the motion, there would still be an adequate alternate means of review perhaps via the collateral- order doctrine or a fresh petition for mandamus challenging the denial, see United States v. Fokker Servs. B.V., 818 F.3d 733, 748–49 (D.C. Cir. 2016); United States v. Dupris, 664 F.2d 169, 173–74 (8th Cir. 1981), and certainly on direct appeal by Petitioner following sentencing (at which point he could raise amicus’s appointment as error), see 28 U.Sgrant of the Government’s motion, and to vacate the District Court’s appointment of amicus—Petitioner has not established that he has “no other adequate means to attain the relief he desires.” .C. § 1291. Petitioner has not cited any case in which our Court, or any court, issued the writ to compel a district court to decide an undecided motion in a particular way—i.e., when the district court might yet decide the motion in that way on its own.
