The title of this report requires „all-inclusive“ reading on this topic which emphasises more the main trends in supervision rather than suggesting closer analysis of various techniques of administration and public activity supervision. That is why we will try to demonstrate the most significant movements such as those which influence the very structure of the system of administrative supervision. We have therefore decided to evaluate the topic of change which appeared in the 80's, taking into account the French experience as the main reference. If considered through the prism of change, we can present three lines of thinking on the current problem area of administrative supervision. The first is related to establishing the key moving forces of change. For us to implement this, we must briefly present three items which can act together or separately: 1. political reorganisation of states and public administrations, 2. constantly refreshing democratic demands and 3. the appearance of managerial paradigm. After this reminder of the moving forces of change, contemplation can move towards the most obvious forms of change: we will focus on two changes which are complimentary but are also possible contradictory while the widening and deepening of traditional forms of administrative court control must include diversity of the means of supervision implementation over public activity. In the conclusion, we have only to question the scope of change which is in force. Apart from the question related to the social efficiency of supervision, one must also raise the question of its contribution to administrative democracy.
