The term 'jeopardy' generally means putting yourself in danger, at risk, or facing some kind of peril. In the law the rule of 'double jeopardy' generally means that a person who is acquitted at one trial should not be in danger of being tried again for the same crime. This rule has been a fundamental principle of most criminal justice systems, especially those based on the common law. Of course there does exist in Australia the possibility of being tried twice where a person who has been acquitted in a criminal court could face a civil court over the same criminal event. The most well-known example of this comes from the USA, where famous footballer and movie celebrity OJ Simpson was acquitted of the murder of his wife Nicole Brown Simpson and acquaintance Ron Goldman in the 1990s, but was later found liable for their deaths in a civil suit.
