论有因性立法模式下的不当得利制度的构造——关于我国不当得利制度适用范围的思考

Construction of Unjust Enrichment System (UES) under the Cause-based Legislation Mode:Further Discussion on the Basis and the Scope of China's UES

不当得利制度与财产权变动无因性原则之间的内在逻辑关联,使奉行物权变动有因性原则的立法在具体设计不当得利制度时存在困境。法国的判例与学说通过种种方式,为克服不当得利制度与物权变动的有因性原则之间的内在矛盾作出了尝试。在我国坚持物权变动有因性立法条件下,使不当得利制度与物权变动有因性的规定相协调的途径是:对不当得利请求权的适用顺序应当给予限制,并将不当得利请求权的适用范围限于作为一般种类物的货币或体现为一般金钱利益的给付行为。

The internal logical connections between unjust enrichment system and the principle of abstraction on property changes plunge legislation guided by the principle of causes on property changes into plight in the specific design system of unjust enrichment. French judicial practices and doctrines through a variety of ways overcome the inherent contradictions between the unjust enrichment system and the principle of abstraction on property rights changes. In China＇ s current legislative conditions we adhere to the the principle of causes on property changes so the effective ways to coordinate the unjust enrichment system with provisions of property rights changes are ： the or- der of the right for unjust enrichment claim should be limited and the application scope of the unjust enrichment claim should be restricted to the currency as a general type of material and payment behavior reflective of the gener- al pecuniary interest.
