阿列克西法律论证理论分为内部证成与外部证成两部分,这两部分并非截然分开,而是相互联系的,内部证成的合理性需要外部证成来保障,外部证成又必然涉及到内部证成,且二者都需要能够被重构为逻辑上正确的过程。做出司法裁判时,只要分析过程是正确的,就必须接受结论,论证理论的细密严谨的论证过程很大程度上保证了做出司法裁判的形式合理性。因此虽然依据论证理论无法实现绝对的确定性,但它已经走在摆脱“明希豪森困境”的路上。 Alexei legal argumentation theory is divided into two parts, internal and external certificates, these two parts are not completely separated, but interrelated, the legitimacy of the internal certification needs external certification to protect the external certificate is inevitable Involves internal certification, and both need to be able to be reconstructed as a logically correct process. When making judicial decisions, as long as the analysis process is correct, we must accept the conclusion that the rigorous and rigorous argument process of the argumentation theory largely guarantees the formal rationality of judicial adjudication. Therefore, although based on the argument theory can not achieve absolute certainty, it has been on the way out of the predicament of “Mythshausen.”
