摘要： 当前中国法学界试图通过建构法秩序统一性原理协调部门法(民法、刑法、行政法)之间的冲突,但学界对法秩序统一性原理的理解存在高度分歧。部门法学界强调实践问题(如民刑交叉),但法理层面的理论反思不足;法理学界则更关注一般性理论建构,但对部门法的差异性不够重视。法秩序统一性原理的建构应以“部门法分立”为起点,理解“法源隔离”的正当性基础,并在此基础上探索“法源跨域流通”的正当条件。法秩序统一性原理的功能是确立法源跨域流通的正当性基础和限度。部门法分立的基础是存在差异化的具体正义原则,法秩序统一性原理的实质是一般正义范畴下诸具体正义原则的互动原理,这为处理中国法律实践中的部门法冲突提供了理论框架。法源流通的正当性基础需围绕各部门法的内在正义原则建构,并进行类型化处理,避免简单以公共政策目的突破部门法边界。

Abstract: Currently, Chinese legal academia attempts to resolve conflicts between departments of a legal system (civil law, criminal law, and administrative law) by constructing the principle of the unity of legal order.However, there is significant divergence in the understanding of this principle, with no consensus yet formed regarding its content and validity.Scholars in specific departments of law emphasize practical issues (such as civil-criminal intersections) but lack theoretical reflection at the jurisprudential level; meanwhile, the jurisprudential community focuses more on general theoretical construction but pays insufficient attention to the differences among departments of law.The construction of the principle of the unity of legal order should start with the “separation of departments of a legal system”, understand the legitimacy of the “isolation of legal sources”, and, on this basis, explore the legitimate conditions for the “cross-domain circulation of legal sources”.The function of the principle of the unity of legal order is to establish the legitimacy and limits of cross-domain circulation of legal sources.The foundation for the separation of departments of a legal system lies in the existence of differentiated principles of justice.The essence of the principle of the unity of legal order is the interactive principle among various specific justice principles under the category of general justice, providing a theoretical framework for addressing conflicts between departments of a legal system in Chinese legal practice.The legitimacy of legal source circulation must be constructed around the inherent justice principles of each legal department and categorized to avoid simply breaching the boundaries of legal departments based on public policy purposes.
