Samenvatting

This article focuses on the current measure for persistent offenders (ISD-measure), by taking into account three equivalent penal sanctions that have been developed in the Netherlands from 1886 onwards. First, the penalty of a labour colony for vagrants and the like for three years at most. Second, the measure to keep the habitual offenders in additional, preventive custody for five to ten years. Finally, the measure of two-year detention for drug addicted offenders. In the article it is argued that in spite of the differences in (judicial) elaboration, all three former existing sanctions have the same legitimating fundamental principle as the ISD-measure. That is, the notion that certain offenders are a danger to society, due to their persistent criminality and nuisance causing lifestyle. The primary objective of all these penal sanctions is therefore a long term protection of society from this danger. In this sense, the ISD-measure makes clear that present state-policy is above all one of sheer deprivation of freedom.
