Resumen
In the last years we have been witnesses of how the legal reforms about gender violence have been followed one another in Spain, and how they were fruitful in the social conscience. Nevertheless, the legal effectiveness of the reforms is still questioned, the judicial decisions often are contradictory, and the violence level is greater than ever or, at least, more visible. This work tries an approach to the study of this matter throw the legislative evolution, analyzing the lights and shadows of the Spanish Criminal System.
