Active citizenship organizations are a relevant reality in the European Union, especially at national and local levels. There is a paradox, however: while citizens and their autonomous organizations are usually asked to contribute with material and immaterial resources to filling the “democratic deficit” of the European Union, they are, at the same time, hardly considered and often mistrusted by public institutions. The EU recognizes collective rights of citizens belonging to political parties, trade unions, employers and professional associations, but not to citizens getting together and acting as actors of public policy making in order to protect rights, take care of common goods, empower weak people. This actual “democratic deficit” of the European Union should be taken seriously. This section of the EUProact website is devoted to the efforts of defining and assessing the implementation of the rights to active citizenship.
