论无权处分的几个问题——关于我国《合同法》第51条的理解与适用

On Several Issues Concerning Ex Right Disposition——Understanding and Application of Article 51 in China's Contract Law

在不同的理论背景下,无权处分的概念及其法律效力多有不同。由于我国在《合同法》立法时民法上没有采纳物权行为理论,因此,德国民法及我国台湾地区"民法"中的无权处分制度与我国《合同法》第51条所规定的无权处分制度存在很大的差异。学者之间围绕"第51条"的适用问题所发生的争议,实质上是对处分、无权处分等概念不同理解所造成的。弄清无权处分的概念并使之与我国民法理论体系相协调,是正确理解和适用"第51条"的前提。

Against different theoretical backgrounds,the concepts and legal effects of ex right disposition are quite different.Because China did not adopt the Theory of Real Right Act in the civil law when the Contract Law was enacted,the system of ex right disposition in Article 51 in China＇s Contract Lawis very different from that in the German and Taiwan Civil Laws.The controversy surrounding the application of Article 51 among scholars is essentially caused by different understanding of concepts such as disposition and ex right disposition.It is the prerequisite for the correct understanding and application of Article 51 to make clear the concept of ex right disposition and to coordinate it with our theoretical system of civil law in China.
