Fifth Amendment Bar to Retrial
Samuel Soto faced federal charges for a capital offense. After a jury was empaneled and sworn the government attempted a second proceeding on the identical conduct. The court invoked the same-offense protection and dismissed the action.
Blockburger Elements Comparison
Simon Stern was prosecuted first for possession of a controlled substance and later for distribution arising from the same transaction. Because each statute required an element the other did not, the court held the charges were not the same offense and allowed both prosecutions to proceed.

Selena Singh stood trial for theft before a jury that was empaneled and sworn. After the judge discharged the panel without manifest necessity, the court ruled that jeopardy had attached and barred retrial for the same offense.
Conspiracy Overt-Act Overlap
Sasha Stone was convicted of conspiracy based on several overt acts. When the government later sought to prosecute her for a substantive offense arising from one of those same acts, the court examined whether the charges constituted the same offense under the indictment correspondence rule.

Accomplice Testimony Protection
Samantha Stone was charged as an accomplice to robbery. After acquittal on that charge, the state attempted to bar her testimony in a codefendant's trial for the identical robbery. The court recognized that acquittal prevented further prosecution for the same offense and allowed the testimony.

Proportionality and Same Offense
Skylar Sullivan received a life sentence without parole for a series of nonviolent offenses. On review the court compared that penalty to sentences imposed for the same offense in other jurisdictions to assess whether the punishment was grossly disproportionate.

Common questions
Frequently Asked
5
How does the Blockburger test determine whether two crimes are the same offense?+
The test asks whether each statutory provision requires proof of an additional fact that the other does not. If both offenses can be proved by the same set of facts without an extra element, they constitute the same offense for double jeopardy purposes.
Supporting sources
When does jeopardy attach in a jury trial so that retrial for the same offense is barred?+
Jeopardy attaches when the jury is empaneled and sworn. After that point the defendant is protected against retrial for the same offense unless the first proceeding ends in a manner consistent with double jeopardy principles such as manifest necessity.
Supporting sources
Does an acquittal on one charge bar a later prosecution for a different statutory offense arising from the same conduct?+
Not automatically. Under the same-elements test the later charge proceeds if each offense requires proof of an element the other does not, even when the underlying facts overlap.
Supporting sources
May a state and a municipality both prosecute a defendant for the same conduct?+
No. A state and its municipalities are not separate sovereigns, so successive prosecutions by both for the same offense violate double jeopardy.
Supporting sources
What happens when a mistrial is declared without manifest necessity after jeopardy has attached?+
Retrial for the same offense is barred because the defendant has already been placed in jeopardy and the proceeding did not end in a manner that permits reprosecution.
