This chapter focuses on the practical, life-altering consequences of the administration of transnational justice, namely of the use of the European Arrest Warrant (EAW). It also focuses on the family aspect, and on some details of how challenges were mounted by the prisoners to the EAW process. The chapter discusses the implications of the EAW process on continued residence of EU nationals in the UK following its departure from the EU. It then comments on the conditionality of residence of EU citizens in the UK before and after Brexit. For the purposes of the chapter, the interview data from the PhD project was supplemented with a review of EAW and Surrender cases reported by Judiciary NI between January 2004 and December 2022. The searches of terms ‘European Arrest Warrant’, ‘Extradition Act 2003’, ‘District Court’, ‘Sad Okregowy’, ‘Poland’ and ‘Republic of Poland’ returned 12 cases, which were then subjected to thematic analysis.
