International extradition exists only by authority of an international treaty with the nation where the fugitive is located. Extradition treaties limit extradition to certain offenses and not all fugitives can be extradited. In some rare cases extraditions can be conditional. For instance, as a condition of extradition from a country that does not implement the death penalty, the prosecutor may agree to limit the maximum sentence to life in prison without the possibility of parole.
