crim. law. One who, having committed a crime within a jurisdiction, goes into another in order to evade the law, and avoid its punishment. 2. By the Constitution of the United States, art. 4, s. 2, it is provided, that a person charged in any state with treason, felony or other crime, who shall flee from justice, and be found in another state, shall, on demand of the executive authority of the same state from which he fled, be delivered up, to be removed to the state having jurisdiction of the crime. The act of thus delivering up a prisoner, is, by the law of nations, called extradition. 3. Different opinions are entertained in relation to the duty of a nation, by the law of nations, independently of any treaty stipulations, to surrender fugitives from justice when’ properly demanded. 4. Before the executive of the state can be called upon to deliver an individual, it must appear, first, that a proper and formal requisition of another governor has been made; secondly, that the requisition was founded upon an affidavit that the crime was committed by the person charged, or such other evidence of that fact as may be sufficient; thirdly, that the person against whom it is directed, is a fugitive from justice. 6 Law Report, 57.
