在刑法理论以及司法实践中,被害人承诺都有其独特的地位和作用。本文对被害人承诺之特殊形式——推定承诺进行阐述,主要明确推定承诺存在的要件。基于推定承诺的行为并没有得到被害人现实的承诺,则其成立必然受到严格的限制。只有在符合特定条件的情况下,才能阻却行为的违法性,成为刑法中的正当化行为。 In the criminal law theory and judicial practice, the victim commitment has its unique position and role. This article elaborates on the special form of victim’s promise - the presumption promise, and mainly specifies the essential elements of the promise. The act of presumption of promises does not get the victim’s actual promise, and its establishment is bound to be severely restricted. Only in the case of certain conditions, we can obstruct the illegal behavior and become the justified act in criminal law.
