Definition - What does Jeopardy mean?
Jeopardy is when a defendant is at risk of being convicted of a crime. It is a state of peril in which an accused person may find himself or herself facing the full consequences of the law if he or she is found guilty. This could include jail time or other punishments.
Justipedia explains Jeopardy
A person who has been in a state of jeopardy is not allowed to again be in jeopardy for the same crime, with the exception of special circumstances, such as a hung jury. So, for example, a person who has been convicted of killing a person can never again be criminally tried for killing the same person; although they may face a civil suit brought against them by the family. This protection from double jeopardy is a right given to all American citizens in the Fifth Amendment of the U.S. Constitution.
