Proper internal organization of a state authority and its office, constructed on the basis of the rules and criteria elaborated by the theorists who make research in this field, is sometimes extremely important for a contemporary state. It is particularly significant in the context of the effectiveness in the activity of the state’s system of authorities, because their organization directly influences the level of their effectiveness. The paper aims at analyzing the organization of the institution of the Romanian Ombudsman called ‘the Advocate of the People’ from the perspective of the rules related to the internal structure of a state authority and its office, as well as its estimation in the context of the effectiveness of the Ombudsman’s activity. The Advocate of the People is a single supreme state authority acting on the central level. It is independent, autonomous and neutral in relations with other state organs. It possesses special legal status which enables it to maintain the abovementioned attributes. It acts with the aid of its deputies, and moreover it is assisted by its office (bureau) being its auxiliary structure, as well as the local offices headed by so-called ‘local Ombudsmen’. The subject of the paper is the role which the Ombudsman and his deputies play in the institution’s activity, the procedure of the deputies’ appointment, their status and competences. The subject also comprises the detailed analysis of the principles of organization of the whole institution, as well as its internal structural units.
