Less is known about their role within the legal system. Meanwhile, interest groups are the driving force behind many high-profile lawsuits against the Dutch government, such as the lawsuits concerning climate change, the quality of asylum facilities, and the Dutch nitrogen policy. This research focuses on the access of interest groups to the courts. How extensive is their access? Does it threaten or protect a democratic society under the rule of law? The access of interest groups to Dutch administrative and civil courts is evaluated in terms of legitimacy and effectiveness. Since interest group litigation is at the intersection of politics and law, the research adopts an interdisciplinary approach. Beyond the boundaries of Dutch legal scholarship, it seeks insights from social sciences regarding the role of interest groups within the political decision-making process. Additionally, it examines, from a legal sociological perspective, the role that interest groups play in public interest litigation in the United States. As a result, the research explores approaches, concepts, and arguments that have largely remained outside of the Dutch legal legal discourse. Ultimately, this leads to a reassessment of both the legitimacy and effectiveness of interest groups' access to the courts. Show less
