Leadership is one of the main roles of institutions and the lack of integrity of certain leaders affects the decision logic. The corruption of leadership degenerates into a pseudo-leadership which benefits from the principle of hierarchy that exists in all organizations. The lack of integrity of the leaders affects decision making and the structure of the organization. Corrupt dynamics often show regular and organized behavior because they adapt to an institutionalized script and to the existence of interpersonal networks. Corruption cases have stimulated in the last decade the elaboration of a legislative repertoire of codes of good governance in public administrations. Good governance codes are tools that aim to regulate the behavior of politicians. This work addresses the study of the preventive efficacy of good governance codes in the face of corrupt frames created in public institutions and focuses on a case study.
