论合同解除后恢复原状请求权的性质——以物权变动模式的选择为基础的考察

就合同解除后恢复原状请求权的性质,旧有的学说大都在理论逻辑上难以自圆其说或者失之偏颇.对此问题不能一概而论,而应当结合物权变动模式的选择以及合同解除的标的详加分析.在意思主义和债权形式主义的物权变动模式下,该请求权为物权性质的所有物返还请求权;在物权形式主义的物权变动模式下,则视合同解除的标的而定:若解除的是物权合同,该请求权仍为物权性质的所有物请求权,若解除的是债权合同,该请求权则为债权性质的不当得利返还请求权.

On the Characteristic of the Claim of Restoring the Original Status Resulted from Rescinding Contracts——A research based on the choice of the transferring mode of real rights

As far as the characteristic of the claim of restoring the original status resulted from rescinding contracts is concerned, the traditional doctrines almost can not justify themselves or have prejudices. This problem should not be judged according to the same standard, but be detailedly analyzed considering the transferring mode of real rights and the object of rescinding contracts. Grounding on the ism of intentions and ism of formations of credit rights, the claim is the one of returning belongings. Grounding on the ism of formations of real rights, the claim's characteristic rests with the object of rescinding contracts: if what is rescinded is the contract of credit rights, the claim is also the one of returning belongings; and if what is rescinded is the contract of real rights, the claim is the one of returning the unjust enrichment.
