涉外民事关系法律适用法中的不当得利规则

"原因关系准据法主义"不仅能彻底解决不当得利识别困扰,而且还体现了不当得利制度的独特功能及其在整个民法体系中独立但"谦逊"的地位,故为当前大陆法系不当得利冲突立法之主流。我国新近施行的《涉外民事关系法律适用法》第47条并未真正采纳"原因关系准据法主义",而以"原因关系冲突规则主义"代之,这在冲突法层面和实体法层面都是值得检讨与反思的。对该法第47条中的"意思自治"和"发生地"作适当的解释,可在一定程度上弥补上述缺憾。

A Discussion on Unjust Enrichment in the Law of the Application of Law for Foreign-related Civil Relations

Lex Causa Condictionis does not only settle the problem of distinguishing unjust enrichment thoroughly,but also reflects the unique function and independent status of unjust enrichment in whole civil law system.Therefore,Lex Causa Condictionis is the main trend of legislation regarding unjust enrichment in civil law jurisdictions.However,Article 47 of the Law of the Application of Law for Foreign-related Civil Relations of the PRC does not accept Lex Causa Condictionis really.Such a significant principle is substituted by the conflict rules of unjust enrichment in China.Self-criticism and introspection are thus necessary.Proper interpretations of "autonomy of the will" and "lex loci actus" may in some degree make up the above mentioned pitfalls.
