This article presents a comprehensive examination of the role of constitutions in private disputes, with a specific focus on the Chinese Constitution. Utilizing an extensive dataset of digitized court adjudications, this study delves into a relatively unexplored area, yielding crucial factual and legal insights. The research reveals that the Chinese Constitution significantly influences civil adjudications, both implicitly and explicitly. Furthermore, court judgments emerge as pivotal forces shaping public awareness of constitutional principles. These findings hold profound implications for comprehending the role of constitutions in contexts beyond democratic frameworks, particularly within the private sphere. The study underscores how the capitalist market in China empowers individuals to assert and safeguard private rights, consequently affording the Constitution a protective role in this realm. Concurrently, the existing regime has systematically eroded the Constitution's influence in public affairs, maintaining its symbolic and rhetorical role. Notably, the concept of judicial independence remains a sensitive subject in China, leading many civil courts to eschew constitutional provisions in favor of political expediency. This paradox underscores the necessity of establishing a reasonably independent judiciary as an integral facet of constitutionalism in such settings. In sum, this research challenges prevailing assumptions about constitutionalism's contours. It transcends the conventional focus on political authority, illustrating how empirical investigations into constitutional performance within civil litigation can illuminate the emergence of constitutionalism in the shadows of non-democratic systems. These findings offer valuable insights into the role of constitutions in private disputes and pave the way for further exploration within this evolving scholarly domain. Ultimately, this study advances our comprehension of constitutional realities and their far-reaching impacts on the legal landscape and society within contemporary China.
