Collective redress mechanisms can be seen in almost all of European countries (except Switzerland and Czech Republic for example). The established regulatory solutions are diverse, basically two lines are typical, and mixed systems based on these are created. One is a representative collective claim enforceable to protect the collective interests of the community (public interest). In general, such claims can only be enforced by government bodies designated by a legislator or by associations whose purpose is the protection of those interests. Another type of collective demand assists the homogeneous demands of a group of individuals by taking advantage of the merged action. In these cases, a person is usually validated by the requirements of the group members, who is himself interested in the proceedings because of his own material right.
