The so-called "Dual-Ausstrahlungswirkung(double effect of expend)" is a new solution for the "Drittwirkungsproblematik(third effect problem of civil rights)". It is different the so far known indirect third effect of civil rights. The three-step-theory serves this difference. The first step is supposed to check the possibility to widen a dimension so public law can expand into the field of private law. The second step checks the present "Ausstrahlungswirkung(effect of expend)" of civil rights as "mittelbare Drittwirkung (indirect third effect)". The third step is about "temporary effect of expend" of civil rights. The debate about the "unmittelbare Drittwirkung (direct third effect) " led so far misjudges the temporary effect of expend of civil rights. The changing order of state and society, influenced by the increasing field of information and the increasing subject of culture within the constitutional life, needs an new idea of constitutional state culture. The so-called "cooperative rule of law" is therefore coming. The term "cooperation" supports the new function and roll of civil rights in the cooperative rule of law or cooperative constitutional state.
