Also known as:lesser included offense doctrine · lesser-included offense doctrine · lesser included offense · LIO doctrine
Written by attorneys · grounded in primary & secondary sources — see below
A principle in criminal procedure that treats one offense as included in another when all of its elements form a subset of the greater offense's elements. The doctrine bars entry of convictions on both offenses arising from the same conduct and treats an acquittal or conviction on the lesser as an acquittal of the greater. It also prevents successive prosecution for the greater offense after jeopardy has attached on the lesser and for the lesser after jeopardy has attached on the greater.

Acquittal on Lesser Bars Greater
Lillian Locke was tried on a single count of insurance fraud after submitting one false claim package. The jury convicted her only of the lesser offense of using false documents and returned no verdict on the greater fraud count. After the trial court later vacated the lesser conviction because of an erroneous accomplice instruction, the state attempted to retry Locke on the original fraud charge arising from the identical submission.
Jeopardy on Lesser Blocks Greater
Latoya Lane pleaded guilty in municipal court to illegal dumping after leaving barrels at a vacant lot. Months later the state indicted her for felony hazardous-waste disposal based on the same barrels and the same act. The felony charge required proof of every element needed for the misdemeanor plus the additional element that the material was hazardous.
Jeopardy on Greater Bars Lesser
Lily Lopez stood trial on a felony odometer-fraud charge. The jury acquitted her of the felony but convicted her of the lesser deceptive-advertising offense based on the same mileage alterations.

Common questions
Frequently Asked
5
When may a defendant be convicted of both a greater offense and a lesser included offense arising from the same conduct?+
A defendant may not be convicted of both when every element of one offense is contained within the other. The prosecution may charge and try both offenses, but the court may enter judgment on only one.
Supporting sources
Does vacation of a lesser-included conviction allow retrial on the greater offense?+
No. A finding of guilty on the lesser included offense constitutes an acquittal of the greater inclusive offense even if the lesser conviction is later set aside.
What happens when a jury convicts on a lesser included offense and returns no verdict on the greater?+
The absence of a verdict on the greater offense operates as an implicit acquittal that bars retrial on the greater charge even after the lesser conviction is vacated.
Supporting sources
Does an express finding of insufficient evidence on a greater offense bar retrial after a lesser conviction is reversed on other grounds?+
Yes. The insufficiency determination constitutes an acquittal of the greater offense that remains effective even though the lesser conviction is later vacated for unrelated reasons.
Supporting sources
May the state prosecute a greater offense after conviction on a lesser included offense from the same act?+
No. Conviction of the lesser bars subsequent prosecution for the greater when the greater requires no proof beyond that needed for the lesser plus additional elements.
