大多数学者认为自八十年代初“二王”案是刑事悬赏应用的开始,而后作为公安机关的一项重要的侦查措施被逐渐广泛应用。我们不可置疑刑事悬赏在现阶段有其存在的必要性。但如何定位刑事悬赏的法律性质,它究竟是一种私法上的契约行为还是单独的法律行为,抑或是一种行政行为——行政奖励。这关乎到一系列的问题,以及出现纠纷时当事人如何救济自己的权益。 Most scholars believe that since the early 1980s, the case of “Two Kings” is the beginning of the application of criminal reward, and then it has been gradually widely used as an important investigation measure of public security organs.
