Background
In 2002, Billy Cooper was convicted by jury of conspiracy, carjacking resulting in death, use of a firearm during a crime of violence, and interstate transportation of a stolen vehicle in the Southern District of Mississippi. Although the government sought the death penalty, the jury unanimously recommended—and the district court imposed—life without the possibility of release on the carjacking count. Cooper received concurrent 57-month sentences on the conspiracy and stolen-vehicle counts, running concurrently with the life sentence, and a consecutive 120-month sentence on the firearm charge.
In 2024, the district court on its own motion reduced Cooper’s sentences on the conspiracy and stolen-vehicle counts to 46 months each, relying on a retroactive change to the Sentencing Guidelines. Cooper moved for reconsideration, contending the district court had miscalculated the reduction. The district court denied the motion, and Cooper appealed, arguing that his carjacking conviction should have been grouped with his other counts and his life sentence reduced accordingly.
The Court’s Holding
The Fifth Circuit affirmed the district court’s decision. The court held that Cooper’s life sentence on the carjacking count was mandated by statute under 18 U.S.C. § 3594, which requires the court to impose life without possibility of release when a jury unanimously recommends that sentence. Because Cooper’s sentence rested on this statutory command rather than on a Sentencing Guidelines range, a retroactive Guidelines amendment could not reach it.
The court rejected Cooper’s argument that offense grouping rules required treating carjacking, conspiracy, and the stolen-vehicle count as a single unit for sentencing purposes. The court also disposed of Cooper’s Double Jeopardy claim, citing United States v. Felix for the proposition that conspiracy and the underlying offense are separate crimes for double jeopardy purposes. Cooper’s challenge to counsel’s conduct also failed because no attorney had filed the motion for reduction—the district court acted on its own motion.
Key Takeaways
- Sentences imposed pursuant to statutory mandate are not subject to reduction under retroactive Sentencing Guidelines amendments, even when such amendments would otherwise lower a defendant’s range.
- Conspiracy and the underlying substantive offense constitute separate crimes for double jeopardy purposes, permitting concurrent sentencing on both counts without constitutional violation.
- District courts may reduce sentences on their own motion under retroactive Guidelines amendments, and their exercise of discretion in denying reconsideration is subject only to abuse-of-discretion review.
Why It Matters
This decision clarifies a critical boundary in federal sentencing law: when Congress prescribes a specific sentence through statute, that sentence is insulated from retroactive Guidelines amendments that would otherwise permit reduction. This preserves Congressional intent in mandatory-sentencing statutes and prevents the Guidelines regime from undermining statutory sentencing frameworks. For carjacking resulting in death—a serious federal crime carrying death-penalty eligibility—this holding ensures that when a jury imposes a life sentence, that sentence stands absent direct appellate review or other extraordinary remedies.
The opinion also provides important guidance on the relationship between conspiracy charges and substantive offenses in federal practice. Defendants convicted of both conspiracy and the predicate crime cannot invoke the Double Jeopardy Clause to bar cumulative sentences, a principle essential to federal prosecutors’ ability to charge conspiracy alongside substantive offenses. This reinforces established doctrine and provides districts with clarity that sentencing on both counts does not violate the Constitution.
