Puerto Rico v. Sanchez Valle

**Puerto Rico v. Sanchez Valle** was a U.S. Supreme Court case decided in 2016 that addressed whether Puerto Rico could prosecute someone for a crime after they had already been tried by the federal government. The Court ruled that Puerto Rico's government and the federal government are essentially the same sovereign entity regarding criminal law. This means a person cannot be tried twice for the same crime in both courts, as it would violate the double jeopardy principle under the Fifth Amendment. Essentially, the ruling clarified the limits of Puerto Rico's autonomy in legal matters.
