The Convention on the Transfer of Sentenced Persons is an international treaty regulating the extradition and social rehabilitation of imprisoned persons. The convention was concluded in Strasbourg on 21 March 1983 and entered into force on 1 July 1985. It has been ratified by 65 countries, including every country of the Council of Europe except Monaco. It has also been ratified by 19 states outside the Council of Europe, including Australia, Canada, Israel, Japan, South Korea, Mexico, and the United States. The convention, in particular, gives foreigners convicted of a criminal offence the possibility of serving their sentences in their home countries.
