In an amicus brief in Gamble v. United States, the State and Local Legal Center (SLLC) asks the Supreme Court not to overrule the “separate sovereigns” exception to the Double Jeopardy Clause. This exception allows states and the federal government to convict and sentence a person for the same conduct.
Gamble was prosecuted for and convicted of possession of a firearm by a convicted felon under both Alabama and United States law. His challenge to the “separate sovereigns” exception is unsurprising given that Justice Thomas joined Justice Ginsburg’s concurring opinion in Puerto Rico v. Sanchez-Valle (2016), which suggested the Court do a “fresh examination” of the “separate sovereigns” exception. These Justices are on opposite ends of the ideological spectrum and typically don’t vote together in close cases.
In Sanchez-Valle the Court held that the Double Jeopardy Clause bars both Puerto Rico and the United States from prosecuting a person for the same conduct under equivalent criminal laws. Puerto Rico isn’t a sovereign distinct from the United States because it derived its authority from the U.S. Congress.
