Legal frameworks and key concepts regulating diversion and treatment of mentally disordered offenders in European Union member states

BackgroundThere is only limited research on the various legal regulations governing assessment, placement and treatment of mentally ill offenders in European Union member states (EU-member states).AimsTo provide a structured description and cross-boundary comparison of legal frameworks regulating diversion and treatment of mentally disordered offenders in EU-member states before the extension in May 2004. A special focus is on the concept of criminal responsibility.MethodInformation on legislation and practice concerning the assessment, placement and treatment of mentally ill offenders was gathered by means of a detailed, structured questionnaire which was filled in by national experts.ResultsThe legal regulations relevant for forensic psychiatry in EU-member states are outlined. Definitions of mental disorders given within these acts are introduced and compared with ICD-10 diagnoses. Finally the application of the concept of criminal responsibility by the law and in routine practice is presented.ConclusionLegal frameworks for the processing and placement of mentally disordered offenders varied markedly across EU-member states. Since May 2004 the European Union has expanded to 25 member states and in January 2007 it will reach 27. With increasing mobility across Europe, the need for increasing trans-national co-operation is becoming apparent in which great variation in legal tradition pertains.
