Facts
- Luis M. Sánchez Valle and Jaime Gómez Vázquez each sold a firearm to an undercover police officer in Puerto Rico.
- Puerto Rico charged each defendant under the Puerto Rico Arms Act of 2000 for illegal firearm sales.
- While the territorial cases were pending, federal grand juries indicted both defendants for the same transactions under analogous federal firearm statutes.
- Each defendant pleaded guilty in federal court.
- The defendants moved to dismiss the Puerto Rico prosecutions, arguing the Double Jeopardy Clause barred successive prosecutions because Puerto Rico and the United States are not separate sovereigns.
- Puerto Rico trial courts dismissed the territorial charges; the intermediate appellate court reversed; the Supreme Court of Puerto Rico reinstated dismissal; the U.S. Supreme Court granted review.
Issues
- Whether Puerto Rico and the United States are “separate sovereigns” under the dual-sovereignty doctrine, permitting successive prosecutions for the same conduct without violating the Double Jeopardy Clause.
Decision
- The Supreme Court affirmed the judgment of the Supreme Court of Puerto Rico.
- The Court held that Puerto Rico and the United States are not separate sovereigns for Double Jeopardy purposes because their prosecutorial authority derives from the same ultimate source: Congress.
- Therefore, the Double Jeopardy Clause bars Puerto Rico from prosecuting defendants for the same conduct after federal prosecution under equivalent criminal laws.
- Justice Ginsburg (joined by Justice Thomas) concurred in the judgment and questioned the dual-sovereignty doctrine’s validity in a future case.
- Justice Breyer (joined by Justice Sotomayor) dissented, arguing Puerto Rico’s present-day self-government should render it a separate sovereign.
Legal Principles
- The Double Jeopardy Clause generally prohibits successive prosecutions for the same offense, but the dual-sovereignty doctrine allows successive prosecutions by separate sovereigns.
- “Separate sovereign” status turns on the “ultimate source” of prosecutorial power, not the degree of current autonomy or self-governance.
- Two prosecuting entities are separate sovereigns only if each draws its power to punish from an independent original source.
- Puerto Rico’s authority to enact and enforce its criminal laws, including under its constitution, ultimately comes from congressional authorization; its constitution does not supply an independent source of prosecutorial power distinct from Congress.
Conclusion
Because Puerto Rico’s and the federal government’s prosecutorial authority ultimately originates from Congress, they are the same sovereign for Double Jeopardy purposes, so Puerto Rico may not bring a successive prosecution based on the same conduct after a federal prosecution under equivalent laws.
