What does the doctrine of Dual Sovereignty permit in criminal prosecutions?

• A. A trial by only the state government if the federal government declines
• B. A trial limited to the federal government only
• C. One trial by both federal and state governments for the same act
• D. A second trial after acquittal by the same sovereign

Answer: (C)

Dual Sovereignty rests on the idea that state and federal governments are separate authorities, each with its own criminal laws and powers. Because they operate independently, the same conduct can violate both state and federal law, so each sovereign may prosecute the person for that act. This means a person can face prosecutions in both venues for the same conduct, even though one might have already occurred in the other’s jurisdiction. The double jeopardy protection applies within a single sovereign, not across different ones, so separate prosecutions by the federal government and a state are allowed. In practice, this is why someone can be tried in state court and in federal court for the same act. The other descriptions don’t fit because they misstate the scope: the doctrine isn’t limited to one government, it isn’t a single joint trial, and an acquittal by one sovereign doesn’t bar the other from prosecuting.
