Major Case Update: Fifth Circuit Declines to Transform How Courts Apply Sentencing Guidelines
The Fifth Circuit Court of Appeals has issued its much-anticipated en banc decision United States v. Vargas, which tasked the Court with deciding how much deference courts should give commentary to the U.S. Sentencing Guidelines following the Supreme Court’s decision in Kisor v. Wilkie. In a fractured decision, the Fifth Circuit held that Kisor does not extend to the Guidelines; rather, Stinson v. United States continues to control without any alteration from Kisor. Thus, the current paradigm remains in the Fifth Circuit absent Supreme Court intervention: the Guidelines commentary is “authoritative unless it violates the Constitution or a federal statute, or is inconsistent with, or a plainly erroneous reading of, that guideline.”
