The legal domain has traditionally been segmented into public and private law. Private law is rooted in the principle of private autonomy that is premised on individual liberty. Conversely, public law centers on the adininistration and regulation of public authority. Despite these distinctions, public and private law overlap significantly in their research topics, methodologies, and goals. As such, collaboration and mutual learning between these spheres are crucial. Consequently, establishing a platform for dialogue among scholars from both fields is deemed valuable. 
 This paper delves into the criteria that differentiate public from private law, examining their interrelation through constitutional and civil law, alongside administrative and civil law. It scrutinizes the nexus between public and private law, with a focus on Supreme Court precedents concerning personality rights, the third party effect (Drittwirkung) of fundamental rights in private relationships, interpretations of law in alignment with the Constitution, the analogy of private law regulations to public contracts or public law contracts, the validity of a contract contravening administrative regulations, the liability for state compensation for unlawful administrative conduct, and the demarcation of jurisdiction between civil and administrative proceedings. Public and private law have evolved in tandem, influencing each other. Their dem邱ation is more a product of historical development and relativity than a priori or theoretical constructs. Recent Supreme Court rulings demonstrate an increasing interplay between public law, including constitutional provisions, and the interpretation and application of civil law, and vice versa. In this scenario, promoting an active dialogue between scholars of public and private law is anticipated to substantially enhance both disciplines, as well as the legal system as a whole.
