This case concerns the First Step Act of 2018, in which Congress made major reductions to the mandatory minimum sentences for certain federal drug and firearm offenses. These changes result in sentences many decades shorter than were required under the previous laws. The question in this case was whether people who were initially sentenced prior to enactment of the First Step Act, but whose sentences were vacated and remanded for resentencing after enactment of the law, can benefit from its major reductions in applicable mandatory minimums. For defendants like Mr. Carpenter, who was originally sentenced to a draconian 116 years in prison as a result of the pre-First Step Act mandatory minimums, applying the First Step Act can mean the difference between dying in prison and having the opportunity to eventually go free. Unfortunately, although there is a split among federal courts of appeals on this question, the Supreme Court denied cert in this case in February 2024.
