Residential surveillance shall be carried out by public security organs. If the people's court or the people's procuratorate decides to monitor residence, it shall promptly deliver the decision on residential surveillance and the notice on the execution of residential surveillance to the public security organ. If the public security and judicial organs decide to monitor residence, they shall make an announcement to the criminal suspect and defendant, and he shall sign or seal the decision on residential surveillance, order the criminal suspect and defendant to abide by the obligations stipulated by law, and inform them of the legal responsibilities they should bear in violation of the regulations. After the announcement, the people's procuratorate and the people's court shall immediately serve the decision on residential surveillance and the notice on the execution of residential surveillance on the public security organ, and inform the public security organ that if it intends to approve the criminal suspect or defendant to leave the residence or meet other personnel during the execution period, it shall obtain the consent of the decision-making organ before approving. The people's courts, people's procuratorates and public security organs shall keep criminal suspects and defendants under residential surveillance for a maximum of six months. If the people's procuratorate or the public security organ has placed the criminal suspect under residential surveillance, after the case is transferred to the people's procuratorate or the people's court, the people's procuratorate or the people's court shall re-apply the residential surveillance procedure to the defendant according to law. The duration of residential surveillance is recalculated. During the period of bail pending trial and residential surveillance, the investigation, prosecution and trial of the case shall not be interrupted. If the term of residential surveillance expires or it is found that the criminal responsibility of the criminal suspect or defendant should not be investigated, the residential surveillance shall be lifted or revoked in time. To remove or cancel residential surveillance, the case-handling personnel shall put forward their opinions and report them to the person in charge of the department for review, and finally the decision shall be made by the person in charge of the public security organ, the chief procurator of the people's procuratorate or the president of the people's court. The decision to remove or remove residential surveillance shall be notified to the executing organ in a timely manner, and the decision to remove or remove residential surveillance shall be served on the criminal suspect or defendant. Criminal suspects, defendants and their legal representatives, close relatives or lawyers entrusted by criminal suspects and defendants have the right to appeal to the people's courts, people's procuratorates and public security organs to terminate the residential surveillance if they think that the residential surveillance has exceeded the statutory time limit. If the situation is true after examination, the residential surveillance of the criminal suspect or defendant shall be lifted. If the examination has not exceeded the statutory time limit, it shall give a written reply to the applicant. The public security and judicial organs shall not take repeated measures of obtaining a guarantor pending trial and residential surveillance against the same criminal suspect or defendant.
