In the Netherlands, the penalization of human smuggling has become broader and more severe. This development is part of a crimmigration trend that describes an increase of immigration-related criminal offenses. Currently, the provision does not include a financial component, nor does it exclude acts with a humanitarian motive. The validity of such severe prohibitions, especially those including acts that are not morally reprehensible, is questioned through the concept of ‘humanitarian smuggling’. Moral reprehensibility is one of the criteria for criminalization that provide a framework for the reflection on the Dutch prohibition of human smuggling that is conducted in this article.

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.

Both in Dutch migration law and criminal law, entry bans, provided for in the Return Directive, play a significant role. The length of an entry ban may exceed five years if the third-country national represents a serious threat to public policy, public security or national security. This article focusses on the definition of ‘serious threat to public policy’ and elaborates on the relevant moment in time in judicial proceedings before the administrative and criminal courts.
