Extradition of criminals within the scope of law no. 6706 and international conventions

This thesis provides a comprehensive analysis of the institution of extradition from both the perspective of Turkish domestic law and international law. The transnational nature of crime and the possibility of offenders fleeing across borders have rendered international cooperation indispensable for states in the pursuit of criminal justice. In this context, extradition has emerged as a fundamental mechanism for combating crime and criminals, as well as for ensuring the right to a fair trial. The primary focus of this study is Law No. 6706 on International Judicial Cooperation in Criminal Matters. This legislation meticulously regulates the procedures and principles governing extradition in Turkiye and grants extensive powers to both executive and judicial authorities. Additionally, the thesis examines the obligations of the state and the practical implementation of extradition mechanisms within the framework of international treaties to which Turkiye is a party. The study elaborates on the core principles recognized under international law concerning extradition—such as dual criminality, the political offence exception, the prohibition of the death penalty, and the non-extradition of nationals. These principles are analyzed in detail in light of both Law No. 6706 and the relevant international conventions to which Turkiye is a signatory. In conclusion, Turkiye's effective implementation of Law No. 6706 and its adherence to its international treaty obligations are of vital importance for the realization of criminal justice and the protection of human rights. The institution of extradition is not merely a technical procedure but a multifaceted legal field situated at the intersection of human rights, state sovereignty, and international security.
