随着引渡制度的产生和发展,出现了一系列引渡原则。双重犯罪原则是其中重要的原则之一,它对于国家相互之间开展引渡合作起着至关重要的作用。它自身的发展又促进着引渡制度的发展。我国《引渡法》和中外双边引渡条约也确定了这一引渡原则。 With the emergence and development of the system of extradition, a series of principles of extradition have emerged. The principle of double criminality is one of the most important principles. It plays a crucial role in the country’s mutual cooperation in extradition. Its own development has in turn promoted the development of the system of extradition. The principle of extradition has also been set by our “Extradition Law” and bilateral extradition treaties both at home and abroad.
