This case asks the Supreme Court to determine whether the Mandatory Victims Restitution Act is a criminal punishment, which would implicate the Ex Post Facto Clause of the Constitution upon retroactive application, or a civil remedy. Petitioner Holsey Ellingburg, Jr. was convicted of bank robbery and firearm use during a violent crime in August 1996 and sentenced under the Victim and Witness Protection Act, which capped restitution enforcement at twenty years after entry of judgment. However, Congress enacted the Mandatory Victims Restitution Act in April 1996 to extend the restitution enforcement period to twenty years after a defendant’s release from prison. Ellingburg argues that, in designing the Mandatory Victims Restitution Act, Congress made a criminal punishment, so retroactively applying it to increase his penalty would violate the Constitution’s Ex Post Facto Clause. Court-appointed attorney John F. Bash, invited to support the judgment below, argues that Congress did not clearly design the Mandatory Victims Restitution Act as a criminal punishment, so it is a civil remedy that does not implicate the Ex Post Facto Clause. The outcome of this case will have a major impact on the fairness of the restitution process for both criminal defendants and victims of crimes.
