Residential surveillance refers to a compulsory measure that people's courts, people's procuratorates and public security organs restrict criminal suspects and defendants from leaving their residences or designated residences within a specified period of time, and monitor their behavior and restrict their personal freedom.
Relevant laws and regulations:
Article 72 of the Criminal Procedure Law: The people's courts, people's procuratorates and public security organs may monitor the residence of a criminal suspect or defendant who meets the conditions for arrest and is under any of the following circumstances:
(1) Suffering from serious illness and unable to take care of themselves;
(2) Women who are pregnant or nursing babies;
(3) Being the sole supporter of a person who cannot take care of himself;
(four) because of the special circumstances of the case or the need to handle a case, it is more appropriate to take residential surveillance measures;
(five) the detention period expires, the case has not yet been settled, and it is necessary to take residential surveillance measures.
For those who meet the conditions of obtaining a guarantor pending trial, but the criminal suspect or defendant cannot provide a guarantor or pay a deposit, they can be placed under residential surveillance.
Residential surveillance shall be carried out by public security organs.
Article 77 The people's courts, people's procuratorates and public security organs shall not release criminal suspects and defendants on bail pending trial for more than twelve months, and shall not keep them under residential surveillance for more than six months.
During the period of bail pending trial and residential surveillance, the investigation, prosecution and trial of the case shall not be interrupted. If it is found that criminal responsibility should not be investigated, or if the term of bail pending trial or residential surveillance expires, the bail pending trial and residential surveillance shall be released in time. When releasing a resident who has been released on bail pending trial, it shall promptly notify the resident who has been released on bail pending trial and the relevant units.
