2 2. Scope of the Rules and definitions used 2.1 The following Standard Minimum Rules shall be applied to juvenile offenders impartially, without distinction of any kind, for example as to race, colour, sex, language, religion, political or other opinions, national or social origin, property, birth or other status. 2.2 For purposes of these Rules, the following definitions shall be applied by Member States in a manner which is compatible with their respective legal systems and concepts: ( a ) A juvenile is a child or young person who, under the respective legal systems, may be dealt with for an offence in a manner which is different from an adult; ( b ) An offence is any behaviour (act or omission) that is punishable by law under the respective legal systems; ( c ) A juvenile offender is a child or young person who is alleged to have committed or who has been found to have committed an offence. 2.3 Efforts shall be made to establish, in each national jurisdiction, a set of laws, rules and provisions specifically applicable to juvenile offenders and institutions and bodies entrusted with the functions of the administration of juvenile justice and designed: ( a ) To meet the varying needs of juvenile offencers, while protecting their basic rigths; ( b ) To meet the need of society; To implement the following rules thoroughly and fairly. Commentary The Standard Minimum Rules are deliberately formulated so as to be applicable within different legal systems and, at the same time, to set some minimum standards for the handling of juvenile offenders under any definition of a juvenile and under any system of dealing with juvenile offenders. The Rules are always to be applied impartially and without distinction of any kind. Rule 2.1 therefore stresses the importance of the Rules always being applied impartially and without distinction of any kind. The rule follows the formulation of principle 2 of the Declaration of the Rights of the Child. Rule 2.2 defines "juvenile" and "offence" as the components of the notion of the "juvenile offender", who is the main subject of these Standard Minimum Rules (see, however, also rules 3 and 4). It should be noted that age limits will depend on, and are explicitly made dependent on, each respective legal system, thus fully respecting the economic, social, political, cultural and legal systems of Member States. This makes for a wide variety of ages coming under the definition of "juvenile", ranging from 7 years to 18 years or above. Such a variety seems inevitable in view of the different national legal systems and does not diminish the impact of these Standard Minimum Rules. Rule 2.3 is addressed to the necessity of specific national legislation for the optimal implementation of these Standard Minimum Rules, both legally and practically. 3. Extension of the Rules 3.1 The relevant provisions of the Rules shall be applied not only to juvenile offenders but also to juveniles who may be proceeded against for any specific behaviour that would not be punishable if committed by an adult.
