Barriers to the implementation of public policies appear long before their implementation. Flawed institutions hamper the proper identification of problems and policy formulation. The main problem is the lack of definition of the decision-making centre, which is the main body responsible for public policy-making. The functional subcontracting of the legislative and executive powers deprives Parliament of its influence over the shaping of public policy. Nor does the government perform its policy-making function. Data from studies show that ministries have taken over this role and that there is a lack of legislative coordination. The law is an instrument for communicating previous decisions. There is no use of objective knowledge or public consultation that could counterbalance the declining role of the parliament. This makes it difficult to select the right instruments for policy implementation.
