À rebours de l'enseignement des historiens, selon lequel les sociétés se pacifient à mesure que leurs mœurs s'affinent, notre société contemporaine semble en proie à une violence omniprésente. Pour autant, ni le scientifique ni le profane n'est véritablement dans l'erreur, car la notion de violence revêt une dimension subjective qui la rend susceptible de variations considérables selon les époques et les communautés. Cette subjectivité dont est empreinte la notion, le droit pénal, ne s'en accommode que difficilement. Fidèle aux principes qui le fondent, et le préservent de l'arbitraire, le droit pénal se doit de définir avec clarté et précision les comportements qu'il entend réprimer. Or, pas plus que la jurisprudence, le législateur n'a pris soin de définir la notion de violence. Pourtant, celle-ci irradie le Code pénal et connaît de surcroît un emploi inflationniste au sein de l'hémicycle, comme en témoigne la répression des violences routières, conjugales, urbaines, scolaires, sportives… S'il est de son office d'encadrer les évolutions de la société, le droit pénal ne doit cependant pas en accompagner les dérives avec bienveillance. Ne serait-ce parce qu'en matière de violence, il souffrirait immanquablement de se voir reprocher celle qui, originellement, est la sienne / Contrary to historian's learning, according to societies pacify themselves as their manners are refined, contemporary society seems plagued by widespread violence. However, neither the scientist nor layman is really wrong, because the concept of violence has a subjective dimension that makes it susceptible to considerable variations across periods and communities.This subjectivity imbuing the concept, criminal law can't admit it easily. Faithful to the underlying principles, and preserve itself of the arbitrary, criminal law should define clearly and precisely the behavior it intends to punish. However, no more than the jurisprudence, the legislature took care to define the concept of violence. Even so, it radiates the Penal Code and has furthermore inflationary employment within the Parliament, as evidenced by the punishment of violence roads, domestic, urban, school, sports... If it's his office to oversee the evolution of society, the criminal law should not, however, support the drifts with kindness. If only because in terms of violence, suffering inevitably be accused of that which, originally, was hers

Una adecuada interpretación del principio de legalidad ofrece buenas razones para admitir la analogía in bonam partem en el Derecho penal aunque de un modo limitado. Incluso cuando el juez mediante ésta excluye o limita el ejercicio del ius puniendi, el aplicador del Derecho penal debe seguir apegado a la ley. De este modo, la analogía in bonam partem debe ser vista como un mecanismo excepcional de integración del Derecho penal frente a inconsistencias axiológicas no previstas ni deseadas por el legislador. Estas excepcionales facultades creadoras reconocidas al juez tienen lugar frente a concretas instituciones jurídico-penales y dentro de un determinado marco argumentativo. En este sentido, la analogía in bonam partem es un medio para crear supralegalmente causas de justificación, causas de exculpación y atenuantes, mientras que no para crear excusas absolutorias. Igualmente, el juez puede crear Derecho solamente a partir de la analogía legis o la analogía institutionis, sin resultar posible acudir a la analogía iuris. / An adequate interpretation of the legality principle offers sound reasons to accept analogy in bonam partem in Criminal Law, though only in a limited way. Even when the judge excludes or limits the ius puniendi through the use of analogy, she should still be strictly subjected to the norm. Therefore the analogy in bonam partem must be seen as an exceptional mechanism of Criminal Law's Integration in the presence of axiological inconsistencies that the Parliament didn't foresee and didn't want. These exceptional law-making powers awarded to the judge refer to specific Criminal law institutions and in a specific argumentative framework. In this sense, analogy in bonam partem is an instrument to supra-legally create justifications, excuses, and mitigating circumstances, but not other types of punishment excluding institutions. In the same manner, the judge can create new Criminal Law only through legis Analogy and institutionis Analogy but not through iuris Analogy.
