Student thesis: Master's Thesis


The proposed dissertation deals with the duty of loyalty of directors in groups of companies. The study of this subject reveals to be opportune due to the relation between the company and the directors and to the insufficiency of the law in the protection of the corporate interest. In this field, different conflicts of interests may arise which may be prevented, on the part of the administrator, if they understand before whom and how they are bound by the duty. This duty together with the duty of care are enshrined in Article 64 no. 1 of the CSC (henceforth CSC). In this dissertation we propose to analyze the basis, extension and content adopted by the duty of loyalty in groups of companies together with the responsibility for its violation, trying to understand its effects for the directors of both the dominated and dominant company.
