論代理的本質以代理權授予時的意思瑕疵問題為契機

在代理之中，民法所標榜的自我決定原理如何實現？ 代理人在代理時的自由意思決定，往往讓人以為意定代理的本質是代理人一人的具有“他人效”的行為。但事實上，意定代理在本質上就是本人與代理人的共同參與。相應地，代理權授予行為與代理行為也應被統合為一個法律行為，由此生髮出代理效果。所以當本人在代理權授予時存在意思瑕疵時，可以依據《民法總則》第146條以下各規定，直接撤銷包括代理行為在內的整個法律行為，或宣告該法律行為無效。

How to give expression to the principle of self-determination proposed by the Civil Law in agency? The free decision of agent in agency tends to be understood to mean that the essence of entrusted agency is the act of the agent with“Fremdwirkung”. But in fact, entrusted agency is essentially the mutual participation of principal and agent. Accordingly, agent's act of agency and the conferment of authority should be integrated into one legal transaction which leads to agency effects. Therefore,when there is the absence of intent in principall's grantaction, according to Article 146 in the General Part of Civil Law, the entire legal transaction including the agent's act of agency can be annulled or declared void.
