Extradition and Whole Life Sentences

Abstract

Sentences of life imprisonment without a prospect of adequate review and release are prohibited in States party to the European Convention on Human Rights. Should the same principle apply when extradition is sought to States not party to the Convention? In Sanchez Sanchez v United Kingdom (2022), the Grand Chamber of the European Court of Human Rights applied a less strict standard for potential extraditees facing life without parole. We analyse this decision and its repercussions in light of the history of international cooperation in extreme punishment cases between Europe and the USA and recent interpretations of the new standard. The article concludes with an assessment of the level of proof litigants must present to satisfy the Sanchez Sanchez test and of how the law could continue to prevent inhuman and degrading treatment of extraditees facing life sentences.
