The article examines the relationship between multiculturalism and law. In particular, she focuses the attention on the case laws invoplving an improper regulatory conflict, which takes into account the fact that a person may commit an act that is envisaged as a crime by the law, while it is allowed or even imposed by rules of his/her culture of origin. In the search for an evaluation criterion capable of legally recognizing cultural-religious traditions, the Author highlights multiple behaviors in which the cultural-religious background assumes great importance and which can integrate, as the case may be, crimes of enslavement, against sexual freedom of persons, violence in the family (hypotheses in which various judicial pronunciations are invoked that, considering the case of the Moroccan family law, deny any exemption from the alleged exercise of a right related to faculties recognized by the State of origin) or, again, case law related to the participation in a terrorist cell.
