This article deals with the criminal offence of recruiting persons for armed struggle (art. 205 of the Dutch Criminal Code), a provision that nowadays mainly arises in terrorism cases. It revolves around the dilemmas and interpretative questions that this criminal offence has yielded so far – especially since the amendments in 2004 – and examines how the courts have dealt with it.

At first sight there seems to be a strong relationship between crimmigration and the criminology of administrative law enforcement. However, a further analysis shows that crimmigration fits more in the concept of the so-called integrated science of criminal justice. Crimmigration can be identified as an interdisciplinary concept, while the criminology of the administrative law enforcement should be classified as an empirical discipline. Nevertheless, both concepts complement each other with regard to the socio-scientific study of the practice of immigration law.
