The effectiveness and legitimacy of action strategies in the realm of spatial decision making Increasing spatial claims require careful decision-making. The question is where, from an institutional point of view, decision-making can best take place. Traditionally, balancing interests takes place in the political arena. Our legal system also guarantees legally anchored interests. In addition, we have expected for decades that participation processes stimulate participation, creativity and co-creation of citizens and entrepreneurs. Moreover, the arrival of the new Environment Act in the Netherlands gives participation a more compelling character: for private initiators, such as project developers, the organization of participation is even a hard requirement in a number of cases. Under the new Environment Act, policymakers, administrators, citizens and companies must constantly make a choice between participating, legalizing or politicizing in decision-making processes. This article analyses this choice from the perspectives of effectiveness and legitimacy. Is decision-making through participation more effective, or are parties better off in the courtroom, or the local council for effective and legitimate decisions? Theoretically, this question is interesting because the answer teaches us about effective and legitimate governance. For the practice of environmental decision-making, we consider when the participatory, legal or political route can best be followed to create both effective and legitimate decisions.
