In this article, we use the example of prison leave to discuss prisoners’ access to justice. Based on a functional comparative analysis between Denmark and Germany, we study the law in action. In Germany, prisoners have a legally prescribed right of access to the courts in cases of denial of prison leave. However, in Denmark prisoners face more barriers when trying to access the court. In our analysis, we have compared Danish court cases with letters from German prisoners referring to their struggles with prison administrations and courts. The materials from both countries show more similarities than one would expect, given the significant differences between the substantive law in the two jurisdictions. While acknowledging the need for further empirical investigation, we introduce a concept we term “genuine justice”, with the aim of paving the way for other and more radical remedies supplementing the economic, legal and social measures already in place.
