不当得利返还请求权和其他请求权的聚合

Polymerization of Unjust Enrichment Claim and Other Claims

不当得利返还请求权和民法上其他请求权,如合同解除后的恢复原状请求权、侵权损害赔偿请求权、基于占有的返还物请求权等存在并存关系。在因同一原因事实而发生多个请求权时,应当从充分救济当事人权利的角度出发,基于不同的给付内容,首先考虑请求权聚合问题,即多个请求权基础共同适用,而不是首先考虑当事人可能获得过多的损害赔偿,而适用请求权竞合规则。即使存在请求权竞合,在请求权目的未完全实现之前,各请求权基础依然可累积适用,以充分保护当事人的合法权益。

There is a coexisting relationship between unjust enrichment claim and other claims in civil law, like restitution claim after the termination of contract, claim in authorized reply relation, and claims for the recovery of damages and so on. When multiple claims occur in the same reason, it should be started from the perspective of relieving sufficiently parties and based on different payment content, problem of claims aggregation should be considered at first. That is the accumulation application of multiple claims, rather than considering that parties may obtain excessive compensation for damages to apply concurrence claims. Even if there is the concurrence of claims, before the purpose of claims is not fully realized, various claims can still be applied cumulatively in order to fully protect the legitimate rights and interests of the parties.
