The actions specific to the insult were taken from the old criminal regulation, in the material element of the crime of "Breach of the solemnity of the meeting", even if it does not represent a priority protection of human dignity as a supreme value. This takeover certifies that the Romanian legislator has learnt a part of the arguments promoted by the Constitutional Court when upholding the unconstitutionality of the repeal of insult and slander. The increased emphasis on the role of the constitutional court, by the diverse range of the adopted solutions, is a reflection of the constitutionalization concept of criminal law that opens new perspectives on the valences of the decisions made by the Constitutional Court.
