Background
Erica Mack pleaded guilty to one count of conspiracy to possess with intent to distribute and to distribute a mixture and substance containing detectable amounts of methamphetamine and fentanyl. The U.S. District Court for the Southern District of Texas imposed a below-guidelines sentence of 108 months in prison.
Mack appealed, arguing that the district court should have granted a mitigating-role adjustment under U.S.S.G. § 3B1.2 and additional offense-level reductions under U.S.S.G. §§ 2D1.1(b)(17) and 2D1.1(a)(5) because she was a minor or minimal participant in the conspiracy. The government responded that the appeal waiver in Mack’s plea agreement barred those sentencing challenges.
The Court’s Holding
The Fifth Circuit dismissed the appeal. Applying de novo review, the court explained that an appeal waiver is enforceable when it was knowing and voluntary and, under the agreement’s plain language, applies to the circumstances presented. The record established both requirements in Mack’s case.
Mack did not challenge or address the waiver’s validity in her opening brief and filed no reply responding to the government’s waiver argument. Because the valid waiver covered her sentencing claims, the panel did not reach the merits of her requested guidelines reductions.
Key Takeaways
- A knowing and voluntary appeal waiver is enforceable according to the plea agreement’s plain language.
- Mack’s waiver foreclosed appellate review of her mitigating-role and related offense-level arguments.
- The court warned defense counsel that pursuing an appeal contrary to a valid waiver without answering the government’s waiver argument wastes judicial resources and could result in sanctions.
Why It Matters
The decision underscores that defendants and counsel must evaluate the scope and enforceability of an appeal waiver before litigating sentencing issues. When the government invokes a facially applicable waiver, failing to contest it can end the appeal without any consideration of the underlying guidelines arguments.
The panel’s express sanctions warning also signals that the Fifth Circuit may treat unsupported appeals barred by valid waivers as more than merely unsuccessful.
