物上請求權乃民法上之核心請求權,其與民法諸多規定有著意義關聯,亦即民法許多規定均與所有人及有權或無權占有這兩項要件有關,而且物上請求權之三項態樣,均有預防損害發生之功能,唯一能與其相比擬之權利,僅有人格權而已。民法第767條規定將無權占有規定成物權返還請求權之發生要件,因而導致依規範理論,所有人就現占有人無權占有一事,負有舉證責任之文義。這項文義,並不妥當。是以應在物權返還請求權之規定內,增訂現占有人就其有權占有一事負有舉證責任之文義,例如:物權人得請求現占有人返還其物。但現占有人有權占有該物者,不在此限。現行法實則存在著占有連鎖(多階層之占有媒介關係)之脈絡,其存在不應是項爭議。為明確這項法律結構,應明文增訂多階層之占有媒介關係。
The claim for return of thing by owner is an important claim in civil law. It has meaning connected with many provisions of civil law. These are related to two elements of the ownership and the right to occupy. The claim for return of thing by owner has the function of preventing future damage occurred. Only the Personality Right in civil law has this function. The meaning of Article 767 of the civil code commands the owner has to proof the occupier has no right to possess. But this meaning is not coordinate with the theory of burden of proof. This provision shall be amended as follow: the owner can request the occupier to return the thing occupied. Therefore, in civil law the multi-class possessions exists indeed. Its existence should not be a dispute. This legal structure should also be clarified in replevin provision.
