Peugh v. United States, 569 U.S. 530 (2013)
In Peugh v. United States, the Supreme Court addressed the critical issue of whether the application of sentencing guidelines promulgated after a defendant's criminal conduct violates the Ex Post Facto Clause of the United States Constitution.
Does the application of sentencing guidelines that provide a harsher sentencing range than those in place at the time of a defendant's offense violate the Ex Post Facto Clause?
The Ex Post Facto Clause prohibits the retroactive application of laws that increase punishment for criminal acts after they have been committed.
The Supreme Court held that applying sentencing guidelines in place at the time of sentencing, rather than those in effect at the time of the offense, violates the Ex Post Facto Clause if the new guidelines result in a harsher penalty.
The Peugh decision is significant as it clarifies the scope of the Ex Post Facto Clause concerning sentencing guidelines. It affirms the importance of adherence to legal standards in effect at the time of the offense, thus protecting defendants from ex post facto legislative changes that could result in increased punishment. For law students, this case offers a critical view into how constitutional protections apply to sentencing practices.
