自由是人的基本权利和实现其他权利的基础和前提,不受任意羁押的权利是被羁押者基本权利中最重要的权利。我国司法实践中存在的高羁押率、超期羁押等问题,与“国家尊重和保护人权”的宪法宗旨相悖,长期为学术界和司法界所关注。在现行司法体制下,尝试完善羁押必要性的检察监督工作机制无疑具有十分重要的现实意义。 Freedom is the basic and prerequisite for the basic human rights and the realization of other rights. The right not to be detained arbitrarily is the most important right of the detainees’ basic rights. The problems of high detention rate and prolonged custody in judicial practice in China run counter to the constitutional purpose of “state respects and protect human rights”, and have long been of concern to academics and the judiciary. Under the current judicial system, there is undoubtedly very important practical significance in the mechanism of procuratorial work to try to perfect the necessity of detention.
