This case asks the Supreme Court to determine whether federal judges may reduce a prisoner’s sentence under the compassionate release statute for reasons that may also fall under a post-conviction motion challenging the legality of a sentence. Joe Fernandez, convicted and sentenced to life on October 7, 2014, for participating in a double murder-for-hire conspiracy, sought a sentence reduction after the trial judge expressed doubts regarding the credibility of the government’s witness and the fairness of the verdict based on extraordinary and compelling reasons. The U.S. Court of Appeals for the Second Circuit reversed and held that prisoners must bring arguments regarding innocence or sentencing errors through the habeas process, not via compassionate release. Fernandez argues that Congress designed the compassionate release statute to afford courts broad discretion to reduce sentences in exceptional circumstances. The United States government, meanwhile, argues that the compassionate release statute is limited to four specific categories of circumstances: age, illness, family hardship, or other circumstances the Bureau of Prisons finds compelling. The outcome of this case will have a major impact on how much discretion federal judges have in revisiting sentences they believe are unjust, thereby clarifying the balance between mercy and finality for criminal defendants.
