物权行为无因性理论之目的论解释

支持或反对物权行为无因性理论者,实质上都是基于某种法律上的意识形态,以一种目的论或功能论的态度加以解释的。在历史上,基于保护交易安全之功能论或目的论来解释物权行为之无因性原则,出现在后期潘德克吞法学中。功能实证分析只是对无因性原则的机能进行一种实证的、中立的描述,与价值判断无涉;目的论是从无因性原则中发现的交易安全之保护机能来进一步论证该原则的正当性,以增强其价值层面的说服力。本文认为,承认物权行为及其无因性原则,符合当代社会侧重保护动的安全之法政策目标,因而在目的论上具有先进性;并且,我们应该充分理解德国法为维系无因性原则和不当得利、善意取得制度在体系上的意义关联而坚持该原则的真正目的。

A Value Explanation of the Principle of Abstraction

As to the principle of abstraction, the positive analysis is merely concerned about a positive and neutral interpretation of its function, and not about value judgment; however, with purpose of enhancing its persuasion in the level of value, the teleology demonstrates further the legitimation of that principle, through emphasizing its function of protecting safety of transaction. This article brings forward that, in view of teleology, accepting juristic act of real right and its principle of abstraction, because of its accordance with the legal policy in the contemporary society, is superior to denying them. Moreover, we should comprehend that the German law's purpose of insisting on the principle of abstraction is to hold together that principle and other rules such as unjustified enrichment and bona fide acquisition.
