Extradition is the formal process of a state that delivers an individual to another state to be pursued or punished for crimes committed in the jurisdiction of the applicant country. It is generally allowed by a bilateral or multilateral treatise. Some states extract without a treaty, but these cases are rare. The extradition treaties help governments to deliver criminals to justice that have fled their country.
An extradition treaty does not guarantee that the signatories will work harmoniously on cases.
