Democratic government is not the same as innovation in government. Government is an important component of democratic theory in the ways in which it relates to the polity as a whole and implements demands made by the people.

In this essay, the issue of innovation is approached through the idea of interfaces between the government and civil society. The author analyzes participatory budgeting, councils, and national conferences in Brazil from the perspective of innovations which have create new interfaces between civil society and the government.
