Extradition

Extradition is the official process whereby one country transfers a suspected or convicted criminal to another country. Between countries, extradition is normally regulated by treaties. Where extradition is compelled by laws, such as among sub-national jurisdictions, the concept may be known more generally as rendition. It is an ancient mechanism, dating back to at least the 13th century BC, when an Egyptian Pharaoh, Ramesses II, negotiated an extradition treaty with a Hittite King, Hattusili III.

Through the extradition process, a sovereign (the requesting state) typically makes a formal request to another sovereign (the requested state). If the fugitive is found within the territory of the requested state, then the requested state may arrest the fugitive and subject him or her to its extradition process. The extradition procedures to which the fugitive will be subjected are dependent on the law and practice of the requested state.

The consensus in international law is that a state does not have any obligation to surrender an alleged criminal to a foreign state, because one principle of sovereignty is that every state has legal authority over the people within its borders. Such absence of international obligation, and the desire for the right to demand such criminals from other countries, have caused a web of extradition treaties or agreements to evolve. When no applicable extradition agreement is in place, a sovereign may still request the expulsion or lawful return of an individual pursuant to the requested state’s domestic law. This can be accomplished through the immigration laws of the requested state or other facets of the requested state’s domestic law. Similarly, the codes of penal procedure in many countries contain provisions allowing for extradition to take place in the absence of an extradition agreement. Sovereigns may, therefore, still request the expulsion or lawful return of a fugitive from the territory of a requested state in the absence of an extradition treaty.

No country in the world has an extradition treaty with all other countries; for example, the United States lacks extradition treaties with Russia, the People's Republic of China, Namibia, the United Arab Emirates, North Korea, Bahrain, and many other countries.
