To effectively counter organised crime and high-risk criminal networks, criminal law alone oftenfalls short. Across the European Union, the administrative approach is increasingly recognised asa crucial strategy to disrupt the infiltration of criminal networks in the legal economy. This studymaps both the legislative framework and practical initiatives that support the administrative approachon organised crime drawing on contributions from six member states: Sweden, Belgium,the Netherlands, Spain, Bulgaria, and Italy. This study maps both the legislative framework andpractical initiatives that support administrative interventions. A structured template was used tocollect country-specific information on relevant laws, the policy framework, and national and localinitiatives. In addition, EU-level strategies and directives were reviewed to assess the broaderpolicy context and identify shared priorities.Findings reveal considerable diversity in the design of the legislative frameworks and initiatives.Countries such as Italy, Belgium, and the Netherlands have developed robust and proactiveframeworks, blending preventive and repressive instruments with administrative possibilitieson the local level. Others, like Sweden, demonstrate how general administrative laws can becreatively adapted to serve crime prevention goals. Spain and Bulgaria show more centrally arrangedadministrative bodies and sector-driven efforts. These differences make it apparent thatthere is no one-size-fits-all model for the administrative approach. Gaining insight into the diverselegal and institutional frameworks across countries enables mutual learning and the identificationof promising initiatives for all member states.Legislation and initiatives at the European level such as AML directives, procurement rules andasset recovery reforms can serve as important enablers, though their impact heavily dependson coordinated implementation. Overall, the administrative approach is gaining attention as anessential component of internal security, offering flexible and preventive tools with local possibilitiesto reduce the infiltration and influence of high-risk criminal networks.
