Double criminality (also known as dual criminality) is a requirement in the extradition law of many countries. It states that a suspect can be extradited from one country to stand trial for breaking a second country's laws only when a similar law exists in the extraditing country.
For example, if Country A has no laws against blasphemy, double criminality could prevent a suspect being extradited from Country A to face blasphemy charges in another country.
Famous quotes containing the words double and/or criminality:
“American families, however, without exception, experience a double message in our society, one that claims a commitment to families and stresses the importance of raising bright, stable, productive citizens, yet remains so bound by an ideal of “rugged individualism” that parents receive little support in their task from the public or private sectors.”
—Bernice Weissbourd (20th century)
“There is no society known where a more or less developed criminality is not found under different forms. No people exists whose morality is not daily infringed upon. We must therefore call crime necessary and declare that it cannot be non-existent, that the fundamental conditions of social organization, as they are understood, logically imply it.”
—Emile Durkheim (1858–1917)
