拟制条件成就是对诚实信用原则的贯彻,其理论构造应遵循“要件——效果”的逻辑展开。在要件层面,不正当行为可表现为作为或者不作为,并通过是否为自己利益予以判断。同时,需对行为人本来的因果关系进程施加了直接或者间接的影响,使得本应成就的条件未成就。此外,一般的可归责性即为已足,无需故意。作为表见拟制,对条件成就的拟制并非典型拟制,其正当性基础在于“任何人不得从其不法行为中获利”。当拟制效果与损害赔偿或者其他法效果并存时,应赋予权利人以选择权。在相似案例中,拟制条件成就的规定存在类推适用的可能性。在法定条件和意愿条件的情形,出于对法律规定以及自由价值的优位考量,条件成就的拟制应受到限制。 Fulfillment of conditional conditions is the implementation of the principle of good faith, and its theoretical construction should follow the logic of “elements - effects”. At the elemental level, the wrongful act can be manifested as act or omission, and judged by whether it is for its own benefit. At the same time, it is necessary to exert a direct or indirect influence on the perpetrator’s process of causality, so that conditions that should be accomplished are not fulfilled. In addition, the general accountability is already sufficient, without intentional. As a tabulation, the formulation of the conditional achievements is not typical fiction. The justification is based on the principle that “no one may profit from his wrongdoing”. When the proposed effect with damages or other legal effects co-exist, should give the right to choose. In similar cases, there is the possibility that analogous conditions may apply. In the circumstances of the statutory conditions and the willingness conditions, due to the superiority considerations of the law and the free value, the formulation of the conditional achievements should be limited.
