What is the core protection of the Double Jeopardy Clause?

• A. No person shall be prosecuted twice for the same offense after a valid acquittal or conviction; exceptions include separate offenses and retrial under certain conditions.
• B. A person may be tried twice for the same offense if the second trial is in a different state.
• C. The clause applies only to federal prosecutions.
• D. There are no exceptions to Double Jeopardy.

Answer: (A)

Double jeopardy protects you from being tried twice for the same offense after jeopardy has attached and ended in a conviction or an acquittal. Jeopardy attaches when the jury is sworn in a jury trial (or when the first witness is sworn in a bench trial) and it ends with a conviction, an acquittal, or certain dismissals. Whether a second prosecution counts as the “same offense” is usually decided by the elements test: if the second offense requires proof of a different element, it’s a separate offense; if not, it’s the same offense. There are recognized exceptions, including when separate offenses arise from different acts, and when a second prosecution is permitted under the dual-sovereign doctrine (federal and state governments) or under limited retrial circumstances. So the best answer states the fundamental protection and the common, allowed exceptions. The other choices misstate the scope or the existence of exceptions.
