The European Union (EU) increasingly develops and implements policies infused with salient and sometimes conflicting values – for instance, in migration and criminal law cooperation. However, policy implementation studies have not frequently considered how such complex value trade-offs may affect practical implementation within Member States. This article therefore quantitatively and temporally examines the practical implementation of an EU flagship criminal law measure: the simplified extradition system known as the European Arrest Warrant (EAW). Using data on EAWs decided upon by the Dutch Amsterdam District Court, we test the impact of value trade-offs by examining whether (newly introduced) safeguards for the protection of requested persons adversely affect system efficiency (measured through case turnover times). The results suggest that the design of legal tests and adjustments made to the EAW system over time through the Court of Justice of the European Union affect the balance between fundamental rights protection and efficiency in the practical implementation of the EAW.

目标与执行之间：欧洲逮捕令实际执行中的价值权衡？

欧盟 (EU) 越来越多地制定和实施充满突出且有时相互冲突的价值观的政策，例如在移民和刑法合作方面。然而，政策实施研究并未经常考虑这种复杂的价值权衡如何影响成员国内的实际实施。因此，本文定量和暂时地研究了欧盟旗舰刑法措施的实际实施情况：称为欧洲逮捕令（EAW）的简化引渡制度。使用荷兰阿姆斯特丹地方法院裁定的 EAW 数据，我们通过检查（新引入的）保护被请求者的保障措施是否对系统效率（通过案件周转时间衡量）产生不利影响来测试价值权衡的影响。结果表明，随着时间的推移，欧盟法院对 EAW 制度进行的法律测试和调整的设计会影响 EAW 实际实施中基本权利保护和效率之间的平衡。
