The article is devoted to the comparative analysis of the development of two types of institutions that act as intermediaries, or mediators; community advisory boards; institutions of the Commissioner for human rights and for the rights of the child.

The subject of the analysis is the history of creation and development, the regulatory framework of these institutions, the personnel and the results of their activities. The results obtained are correlated with an earlier proposed set of models of interaction between the authorities and society. The article concludes: in the conditions of a mono-centrist political regime, the one which is very close to authoritarian, some of the institutions, in particular, the Community Council and the Commissioner for human rights in 2010-2012 acted within the paternalistic model, others, like the Coordinating Council of Non-Profit Organization and the Commissioner for the rights of the child, promoted the partnership model. The institution of the Commissioner for the rights of man under I.P.Mihaylov was in search of its place and its model, but when there appeared a real prospect to act within the partnership model, he was retired.

Recommendation: different levels of authorities are suggested using the practice to involve into the public advisory boards people from really working public organizations, not representatives of "the public", who have nobody to lean on and who are not responsible for their actions/inactions to their organizations.
