United States v. Mercado

Court of Appeals for the Second Circuit · August 25, 2025 · No. 25-206-cr

Summary

The Second Circuit reviewed a district court's denial of the government's motion to detain a defendant pending supervised release revocation proceedings. The appellate court held that it had jurisdiction over the appeal and determined that 18 U.S.C. § 3143(a)(1) provides statutory authority to detain a supervisee awaiting revocation proceedings, reasoning that supervised release is a component of the original sentence. The case was remanded for the district court to determine whether detention is warranted.

Questions Presented

  1. Whether this Court has appellate jurisdiction over the district court’s order denying the motion to detain under 28 U.S.C. §1291 and 18 U.S.C. §3145(c).
  2. Whether 18 U.S.C. §3143(a)(1) authorizes detention of a supervisee pending revocation proceedings.

Holdings

  1. We conclude that we have jurisdiction to hear this appeal because an order related to detention or release, under Section 3145(c), constitutes a final order under Section 1291 that may be appealed to this Court.
  2. Section 3143(a)(1) authorizes detention of a defendant charged with a supervised release violation pending revocation proceedings because the defendant has been "found guilty of an offense" under his original conviction and is "awaiting . . . execution" of the portion of his sentence that authorizes revocation.

Key quotations

We further hold that Section 3143(a)(1) authorizes such detention because a supervisee was found “guilty of an offense” when he was originally convicted and, with the initiation of revocation proceedings, is “awaiting . . . execution” of a portion of his sentence for that conviction. (at 1)

Factual background

Mercado was convicted in 2014 of two heroin conspiracy offenses and sentenced to 120 months imprisonment followed by five years supervised release. In November 2024 he was arrested on state drug charges, alleged to have violated his supervised‑release condition prohibiting further offenses. The government moved to detain him pending revocation; the district court denied the motion.

Procedural history

The district court denied the government’s motion to detain Mercado pending revocation of supervised release, holding that the Non‑Detention Act required statutory authority which it found lacking. The government appealed, asserting jurisdiction under 28 U.S.C. §1291 and statutory authority under 18 U.S.C. §3143(a)(1).

Remand instructions

The district court shall determine on remand whether detention is warranted pursuant to Section 3143(a)(1) and Federal Rule of Criminal Procedure 32.1(a)(6).
