Pueblo v. Sanchez Valle, 192 D.P.R. 594, 2015 TSPR 25 (Mar. 20, 2015); cert. granted, 136 S. Ct. 28 (2015).
Holding
The dual sovereignty doctrine does not apply to the U.S. territory of Puerto Rico. Therefore, the Double Jeopardy Clause bars Puerto Rico and the United States from successively prosecuting a single person for the same conduct under equivalent criminal laws.
In a 6–2 decision, the Court affirmed that the Double Jeopardy Clause bars Puerto Rico and the United States from successively prosecuting the same person for the same conduct under equivalent criminal laws.
The decision was affirmed 6-2 in an opinion by Justice Kagan on June 9, 2016. Justice Ginsburg filed a concurring opinion in which Justice Thomas joined. Justice Thomas filed an opinion, concurring in part and concurring in the judgment.
Justice Breyer filed a dissenting opinion in which Justice Sotomayor joined.[3]
