Abstract: Sealing of misdemeanor criminal record is to limit the outflow of criminal record, to ensure that the information about juvenile criminals only circulate in the system of Public Security Agency, Procuratorial Agency and Court of Justice, and to avoid"label effect" on them caused by non-normative evaluation after the outflow.Though the revised Criminal Procedure Law provides the misdemeanor criminal records storage system, specific operating procedures have not been constituted.A Jiangsu court applied hearing procedure and other processes to sealing the criminal records, which has achieved remarkable effect.This experiment is a useful experience for the further study and the establishment of normative sealing operating procedures.
