This paper examines the general principles that guide the classical treatment of an offender's dangerousness in the criminal codes of sixteen European countries. It provides a review of the way in which each penal code deals with both multiple offenders and the terms of parole. There is substantial variety in the legal definitions and effect of recidivism, with some very strict criteria in place in some states. The same various degree of arbitrariness and lack of clear standards apply to the terms of parole. Though arbitrariness in the administering of these legal categories is common throughout Europe, it can be observed that European penal codes are otherwise vastly heterogeneous.
