Based on interviews with bureaucrats and judges in several Swiss cantons, this article analyzes how bureaucrats decide to order immigration detention and how the judicial review shapes their decisions. The authors argue that discretionary decision-making regarding immigration detention is structured by the web of relationships in which decision-makers are embedded and affected by the practices of other street-level actors. The varying cantonal configurations result in heterogenous bureaucratic practices that affect the profiles and numbers of persons being detained. In particular, differences in judges’ interpretation of legal principles, as well as in their expectations, strongly affect bureaucratic decisions.

本文基于对瑞士几个州的官僚和法官的采访，分析了官僚如何决定下令移民拘留以及司法审查如何影响他们的决定。作者认为，关于移民拘留的自由裁量决策是由关系网构成的，决策者嵌入其中并受到其他街头行为者的影响。不同的州配置导致异质的官僚作风，影响被拘留者的概况和人数。特别是，法官对法律原则的解释以及他们的期望的差异，强烈影响了官僚主义的决定。
