认罪认罚从宽制度被追诉人反悔权研究
Research on the Regret of the Respondent in the System of Leniency for Confession and Acceptance of Punishment

以“认罪认罚权利说”和“契约禁止反言”等视角证成或证否认罪认罚制度中被追诉人的反悔权，并不能充分反映认罪认罚制度的立法精神、实现理论上的逻辑自洽。承认被追诉人享有反悔权，既有从“自愿性”的角度保障制度顺畅进行的务实考量，也在一定程度上体现出无罪推定、反对强迫自证其罪的现代刑事法治精神。从立法论到解释论，允许认罪认罚制度中被追诉人反悔，就必须在理论层面解决“反悔后是否从宽、如何从宽”“反悔后如何适用诉讼程序”“反悔后先前供述的证据效力”等问题，以实现认罪认罚从宽承载的制度价值。
From the perspective of “the right to leniency for confession and acceptance of punishment” and “estoppel in contract”, it cannot fully reflect the legislative spirit of the system of leniency for con-fession and acceptance of punishment. Admitting that the accused has the right of estoppel not only has the practical consideration of ensuring the smooth progress of the system, but also reflects the modern criminal legal spirit of presumption of innocence and opposing forced self incrimination to a certain extent. From the theory of legislation to the theory of interpretation, to allow the accused to repent in the system of leniency for confession and acceptance of punishment, we must solve the problems of “whether to be lenient after repentance, how to be lenient”, “how to apply the litigation procedure after repentance” and “the evidence effect of previous confession after repentance” in the theoretical level, so as to realize the system value of leniency for confession and acceptance of pun-ishment.
