What is the effect of a writ of habeas corpus being appealed?

While his petition was pending, on October 28, 2019, Sow moved the district court for a writ of habeas corpus under 28 U.S.C. 2241, arguing that his prolonged detention violated his statutory and constitutional rights and that he was entitled to a bond hearing before an immigration judge. The district court agreed and, on August 27, 2020, entered judgment, granting the petition and ordering an individualized bond hearing. See Sow v. Barr, No. 6:19-cv-6794, 2020 WL 5046263, at *8 (W.D.N.Y. Aug. 27, 2020). That hearing resulted in Sow's September 14, 2020 release from custody, when he posted the bond set by the Immigration Judge. The government's timely appeal of the district court's habeas judgment is now before this court. We assume the parties' familiarity with the underlying facts, procedural history, and issues in this appeal, as well as in Sow's related petition in No. 19-2464.

Insofar as the government here challenges the district court's writ requiring a bond hearing "where an individualized determination can be made as to whether [Sow] should remain confined for the duration of his immigration proceedings," Sow, 2020 WL 5046263, at *8, our denial of the petition for review in Sow v. Garland, No. 19-2464, filed today, concludes those proceedings. The government is thus no longer encumbered by the writ entered against it, so this court is unable to grant "any effectual relief whatever." Mills v. Green, 159 U.S. 651, 653 (1895). This moots the appeal. See id.
