Background: The essence of a constitutional system lies in two key aspects: limiting state power and ensuring the supremacy of rights, particularly the protection of human rights and freedoms. Without mechanisms to limit state power, the state inevitably encroaches on society and the private lives of individuals, threatening their rights and freedoms. The evolution of constitutional systems in liberal-democratic countries has been closely tied to strengthening civil society and developing tools for controlling state power. Historically, this evolution has moved from an absolute state, where the state was the sole owner and source of power, to a liberal-democratic state, where the state serves the people and civil society. Alongside this historical shift, there has been a transformation of individuals from being mere cogs in the machinery of state power to becoming citizens of a constitutional state, demanding that the state exercise restraint to safeguard individual freedom. One of the central ideas of constitutionalism is the principle of limited government. This article aims to analyse the legal positions of the Constitutional Court of Ukraine concerning the doctrine of limited government. In particular, it explores how the Court interprets key elements of this doctrine, such as the rule of law, the separation of powers, the rights of individuals and citizens, and the doctrine of constituent power. These and other related issues form the core of the research presented in this article. Methods: The study employed several methods to examine the doctrine of limited government, its elements, and the legal positions related to this issue. The system-structural method was used to characterise the concept and content of the doctrine of limited government and its key elements, including the principle of the rule of law, the principle of separation of powers, the rights of individuals and citizens, and the doctrine of constituent power. The logical-legal method facilitated an understanding of the perspectives of scholars on the formation and development of the doctrine of limited government, as well as their views on the content of its elements. Additionally, legal methods such as examining constitutional texts, primary legislation, and case law were employed to analyse the legal positions of the Constitutional Court of Ukraine. Results and Conclusions: The study examines the historical development and current state of the concept of limited government, exploring its connections with the doctrine of constituent power, the principle of the rule of law, the concept of human rights and freedoms, and the principle of the separation of powers. The primary conclusion is that the legal positions of the Constitutional Court of Ukraine regarding the doctrine of limited government, a key pillar of modern Ukrainian constitutionalism, have been systematically reviewed. It has been established that the Constitutional Court of Ukraine has consistently affirmed the essential elements of the doctrine of limited government from its inception. These elements form the doctrine of constituent power and the fundamental principle of constitutionalism, emphasising the necessity of limiting state power to safeguard human rights and freedoms. Furthermore, the Court upholds the view that the organisation and exercise of state power based on the division into legislative, executive, and judicial branches is not an end in itself but is intended to ensure the protection of individual rights and freedoms.
