Introduction

In Mar v. Peugh, 133 S.Ct. 2072 (2013), the United States Supreme Court addressed a significant constitutional issue concerning the Ex Post Facto Clause in the context of federal sentencing guidelines. The case involved Marvin Peugh, who was convicted of multiple counts of bank fraud for actions committed in 1999 and 2000. At the time of his sentencing in 2010, the Federal Sentencing Guidelines had been updated, resulting in a substantially higher sentencing range than what was applicable when Peugh committed his offenses. Peugh argued that applying the newer, more severe guidelines retroactively violated the Ex Post Facto Clause of the U.S. Constitution. The Supreme Court’s decision in this case established a pivotal precedent regarding the application of updated sentencing guidelines and their constitutional implications.

Summary of the Judgment

The Supreme Court reversed the Seventh Circuit’s decision, ruling in favor of Peugh. Justice Sonia Sotomayor, delivering the majority opinion, held that sentencing a defendant under the Federal Sentencing Guidelines promulgated after the defendant committed the offense—which result in a higher sentencing range—violates the Ex Post Facto Clause. Specifically, the Court determined that applying the 2009 Guidelines to conduct committed in 1999-2000, which significantly increased Peugh’s potential imprisonment from 30-37 months to 70-87 months, constituted an unconstitutional retrospective enhancement of punishment.

Analysis

Precedents Cited

The Court extensively referenced previous landmark cases to build its legal framework:

• Booker v. United States, 543 U.S. 220 (2005): Held that the Federal Sentencing Guidelines are advisory rather than mandatory, allowing judges discretion in sentencing.
• MILLER v. FLORIDA, 482 U.S. 423 (1987): Determined that applying amended sentencing guidelines that increase a defendant’s sentence violates the Ex Post Facto Clause.
• Gall v. United States, 552 U.S. 38 (2007): Established that district courts must begin sentencing by correctly calculating the applicable Guidelines range.
• GARNER v. JONES, 529 U.S. 244 (2000): Defined the Ex Post Facto Clause’s focus on the risk of increased punishment.
• DOBBERT v. FLORIDA, 432 U.S. 282 (1977): Emphasized that the Ex Post Facto Clause’s scope is shaped by an accumulation of case law.

Legal Reasoning

The Court’s reasoning centered on the nature of the Ex Post Facto Clause, which prohibits laws that retroactively increase the punishment for criminal conduct. Despite the Sentencing Guidelines being advisory post-Booker, the Court concluded that updating the Guidelines to impose harsher sentences retrospectively still posed a significant risk of increased punishment, thereby violating the Constitution. The majority emphasized that the guidelines effectively influence sentencing outcomes, even if not legally binding, because they serve as a major factor in sentencing decisions and appellate reviews. Thus, the retrospective application of more severe guidelines undermined the fundamental fairness protections intended by the Ex Post Facto Clause.

Impact

This judgment has profound implications for federal sentencing practices:

• Guidelines Applicability: Courts must adhere to the Guidelines in effect at the time the offense was committed, not at the time of sentencing.
• Legislative Stability: Ensures that defendants are not subjected to harsher penalties due to later amendments in sentencing guidelines.
• Judicial Discretion: While still maintaining judicial discretion post-Booker, this decision limits the extent to which guidelines can retroactively influence sentencing.
• Future Legislation: Legislators must consider the constitutional constraints when amending Sentencing Guidelines to prevent ex post facto violations.

Conclusion

The Supreme Court’s decision in Mar v. Peugh underscores the constitutional safeguards against retroactive enhancements of punishment. By affirming that applying more severe sentencing guidelines post-offense violates the Ex Post Facto Clause, the Court ensures that defendants are not subjected to unforeseen and harsher penalties based on legislative changes after their criminal conduct. This ruling reinforces the principle of legal stability and fairness, maintaining the integrity of the criminal justice system by protecting individuals from arbitrary increases in punishment. Future cases involving the retrospective application of sentencing guidelines will now have a clear precedent to reference, shaping the balance between legislative updates and constitutional protections.
