In 1825, the U.S. Supreme Court stated: “The Courts of no country execute the penal laws of another.” One hundred and fifty one years later, in a very different world, the United States signed prisoner transfer treaties with its neighbours, Canada and Mexico. Today, through additional bilateral treaties and multilateral treaties negotiated under the auspices of the Council of Europe and the Organization of American States, the United States has prisoner transfer treaty relations with 77 countries. This treatise, designed for prosecutors, defense attorneys and academics, describes in detail the legal basis and operation under these treaties from the perspective of the United States by the former Department of Justice official responsible for their initial implementation. Additional titles by Michael Abbell include: • Extradition to and from the United States 2010 • Obtaining Evidence Abroad in Criminal Cases 2010 This is the final Edition, there will be no further updates for this series.
