审前羁押制度具有实现国家刑罚权和保障公民权利的双重功能。韩国将期限较短的逮捕措施与期限较长的羁押措施相分离，奉行双重司法审查模式；羁押审查程序体现出司法性、公开性、救济性等特点。整体而言，韩国审前羁押审查制度侧重对侦查权的制约和对被追诉人基本人权的保障。
The pretrial detention system has the dual functions of realizing the national penalty power and protecting civil rights. ROK separates the short-term arrest measure from the long-term custody measure and pursues the dual judicial review mode. The procedure of custody review embodies the characteristics of judicature，openness and relief. On the whole，the pretrial detention review system in ROK focuses on the restriction of investigation power and the protection of the basic human rights of the accused.
