未决羁押作为一种刑事强制措施,是为了保障诉讼活动顺利进行,最终维护人权,具有目的上的正当性,然而其适用的最直接后果是被羁押者的人身自由权利受到了限制。从未决羁押存在的必要性及限制未决羁押的法理基础角度对该项制度作一系统研究,以期能为我国未决羁押制度的重新构建在理论层面作一引玉之砖。 As a kind of criminal coercive measure, the pending detention is to guarantee the smooth progress of the litigation activities and ultimately to safeguard human rights with the purpose of legitimacy. However, the most direct consequence of its application is that the detainees’ personal freedoms are restricted. This system is systematically studied from the perspective of the necessity of pending detention and the jurisprudence of restricting the pending detention, with a view to making a theoretical reference to the reconstruction of the pending detention system in our country.
