法秩序统一性原理之所以被普遍接受为一项处理法域关系的原则，是因为其是以法律的层级构造理论、法的安定性、平等原则以及体系解释的要求作为其背后的理论支撑的。法秩序统一性原理本身是一个富有弹性的概念，其唯一的刚性内涵在于，要求整体法秩序内部的所有法律规范发出的行为指引必须一致。但除此之外，法秩序统一性原理允许不同法域基于各自的目的性思考设定差异性的规范标准，只是在解释论上应为这种差异性的标准提供论证。法秩序统一性原理在法律适用中以体系解释的面向发挥作用；同时，法秩序统一性也是一种解释的产物。法秩序统一性原理本身不是一个可以藉此直接得出具体解释结论的理由，而是要结合其他实质内容才能发挥作用的诠释性理论。关于犯罪认定中的法秩序统一性原理的探讨，要务实地检讨哪些法域之间的规范冲突是法秩序统一性原理所允许的，哪些规范冲突是法秩序统一性原理所不能允许的，以建立处理法域冲突的解释规则。法秩序统一性原理在犯罪认定中的适用要结合犯罪论体系。在犯罪论体系中，刑法构成要件所推定是相对独立的刑事不法概念，决定刑事不法与其他法域的不法的差异；而在违法性阶层则只是寻找所有法域中的允许性规定，以阻却由构成要件推定的刑事不法。刑事的最后手段性、刑事不法的法益侵害性可以为不同法域的不法概念的差异提供解释论上理由，其中刑法的最后手段性决定了刑事不法可以与其他法域的不法存在质和量的差别；刑事不法的法益侵害性决定了刑事不法必须具备其他法域的不法可能不具备的严重的法益侵害性。法秩序统一型原理在犯罪认定中的适用，应区分其他法域存在禁止性规定和存在允许性规定的情形，在前一种情形应当使刑事不法的判断相对地从属于其他法域的不法，在行为违反其他法域的禁止性规定的基础上对刑事不法进行二次判断；在后一种情形则要使刑事不法的判断绝对地从属于其他法域的不法，这一判断既可以在阻却构成要件符合性的层面进行，也可以在阻却违法性的层面进行。

The reason why the principle of unity of law order is universally accepted as a principle for dealing with jurisdictional relations is because it is based on the theory of hierarchy of law, the stability of law, the principle of equality, and the requirements of system interpretation. The principle of unity of law order itself is a flexible concept, and its only rigid connotation is that the rules of conduct issued by all legal norms within the overall law order must be consistent. But besides this, the principle of unity of law order allows different jurisdictions to set different normative standards based on their own thinking, but it should only provide arguments for such differences in interpretation. The principle of unity of law order plays a role in the application of law in the application of law; at the same time, the unity of law order is also a product of interpretation. The principle of unity of law order is not a reason for directly drawing conclusions, but an interpretative theory that can be combined with other substantive contents.With regard to the discussion of the principle of unity of law order in criminal identification, it is necessary to pragmatically review which normative conflicts between jurisdictions are permitted by the principle of uniformity of legal order, and which normative conflicts cannot be allowed by the principle of uniformity of legal order. Interpretation rules for jurisdictional conflicts. The application of the principle of unity of law order in criminal identification should be combined with the criminal theory system. In the criminal theory system, the constitutional elements of the criminal law are presumed to be relatively independent criminal unlawful concepts, which determine the illegal differences between criminal law and other jurisdictions. In the illegal class, only the permissible provisions in all jurisdictions are sought to hinder the constitution. The criminal presumption of the presumption. The final instrumental nature of criminals and the criminal infringement of criminal law can provide explanational reasons for the differences in the illegal concepts of different jurisdictions. The final instrumentality of criminal law determines the difference between the quality and quantity of criminal lawlessness and the illegality of other jurisdictions; The criminal infringement of criminal law determines that criminal law must have serious legal infringement that may not be possessed by other jurisdictions.The application of the principle of uniformity of law order in the identification of crimes should distinguish between the prohibition of prohibition and the existence of permissible provisions in other jurisdictions. In the former case, the judgment of criminal unlawfulness should be relatively subordinate to the illegality of other jurisdictions. Violation of the prohibition of other jurisdictions on the basis of the second judgment of criminal misconduct; in the latter case, the judgment of criminal unlawfulness is absolutely subordinate to the illegality of other jurisdictions, this judgment can not only hinder the conformity of constituent elements The level of progress can also be carried out at the level that blocks illegality.
