Jeopardy on Lesser Precludes Greater
Noreen Nguyen faced charges for a series of deceptive trades that generated undisclosed commissions. After jeopardy attached on the lesser self-dealing count based on those trades, prosecutors sought to pursue the greater securities fraud offense arising from the same conduct.

Greater Prosecution Bars Lesser Retrial
Nora Nash was prosecuted for felony hazardous-waste disposal. After jeopardy attached on that greater charge, the state sought to pursue the lesser illegal-dumping offense arising from the same barrel placement.
Conviction Vacated Yet Bar Remains
Naveen Nanda was convicted at trial solely of a lesser deceptive-advertising offense after the jury returned no verdict on the greater odometer-fraud count. The lesser conviction was later vacated for instructional error, and the state refiled the greater charge on the same mileage alterations.
Implicit Acquittal Prevents Reprosecution
Noelle North stood trial on a conspiracy count and was convicted only of the lesser unauthorized-resale offense with no verdict returned on the greater charge. After the lesser conviction was vacated, prosecutors filed a new information alleging the original conspiracy based on identical ticket resales.
Nestor Navarro was convicted of the lesser patient-neglect misdemeanor after acquittal on the greater felony neglect count arising from the same dosage error. The state later brought a homicide prosecution based on the identical medication incident and resulting death.
Common questions
Frequently Asked
4
When does conviction of a lesser included offense bar prosecution for the greater offense?+
Conviction of the lesser included offense operates as an acquittal of the greater offense under double jeopardy principles. The bar applies even if the lesser conviction is later vacated for reasons unrelated to sufficiency on the greater charge.
Supporting sources
May a prosecutor obtain convictions for both a greater offense and its lesser included offense arising from the same conduct?+
No. When one offense is included in another because all elements of the lesser are contained within the greater, the court may enter only one conviction. The proper remedy is to vacate the lesser included conviction and leave the greater standing.
Supporting sources
Does attachment of jeopardy on a lesser included offense prevent later prosecution for the greater offense?+
Yes. Once jeopardy attaches on the lesser included offense, the Double Jeopardy Clause bars subsequent prosecution for the greater offense arising from the same conduct because the greater requires no additional proof beyond the lesser plus one or more elements.
Supporting sources
What happens when a jury convicts only on the lesser included offense and returns no verdict on the greater?+
The absence of a verdict on the greater offense constitutes an implicit acquittal. That acquittal remains effective even after the lesser conviction is vacated, barring retrial on the greater charge.
