What is "double jeopardy"

n. (context legal English) The act of trying someone twice for the same offense, especially after an acquittal in the first trial.

n. the prosecution of a defendant for a criminal offense for which he has already been tried; prohibited in the fifth amendment to the United States Constitution

Double jeopardy is a procedural defence that forbids a defendant from being tried again on the same (or similar) charges in the same case following a legitimate acquittal or conviction. In common law countries, a defendant may enter a peremptory plea of autrefois acquité or autrefois convict (autrefois means "in the past" in French), meaning the defendant has been acquitted or convicted of the same offence and hence that they cannot be retried under the principle of double jeopardy.

If this issue is raised, evidence will be placed before the court, which will normally rule as a preliminary matter whether the plea is substantiated; if it is, the projected trial will be prevented from proceeding. In some countries, including Canada, Mexico and the United States, the guarantee against being "twice put in jeopardy" is a constitutional right. In other countries, the protection is afforded by statute.

Double Jeopardy is a 1999 American adventure crime- thriller film directed by Bruce Beresford and starring Tommy Lee Jones, Ashley Judd, and Bruce Greenwood. The film is about a woman who slipped away from her parole officer after being framed for the murder of her husband.

Double jeopardy is an empirical law in marketing where, with few exceptions, the lower market share brands in a market have both far fewer buyers in a time period and also lower brand loyalty.

The term was originally coined by social scientist William McPhee in 1963 who observed the phenomenon, first in awareness and liking scores for Hollywood actors, and later in behaviours (e.g. reading of comic strips and listening to radio presenters). Shortly afterwards Andrew Ehrenberg discovered the Double Jeopardy law generalised to brand purchasing. Subsequently Double Jeopardy has been shown to apply across categories as diverse as laundry detergent to aviation fuel, across countries and time.

This empirical law-like phenomenon is due to a statistical selection effect that occurs if brands are broadly substitutable selling to much of the same types of people (often referred to as a lack of Product differentiation and market partitioning). The Double Jeopardy empirical generalization is explained and predicted by the NBD-Dirichlet theory of repeat purchase. See also Schmittlein, Bemmaor and Morrison (1985).
