Search warrant is a judicial instruction of public security organs (including national security), people's courts and people's procuratorates to collect criminal evidence and arrest criminals. With the approval of the heads of public security organs, state security organs, people's courts and people's procuratorates at or above the county level, investigators may search the bodies, articles, residences and other relevant places of criminal suspects and people who may hide crimes or criminal evidence. 1. The search warrant of the public security organ shall be issued by the person in charge of the public security organ at or above the county level. The search warrant of the people's procuratorate shall be issued by the chief procurator. The search warrant shall be stamped with the official seal of the issuing unit. In addition, if the person subjected to execution fails to fulfill the obligations specified in legal documents and conceals property, the people's court has the right to issue a search warrant to search the person subjected to execution and his residence or property hiding place, and the search warrant shall be issued by the president. 2. The searched person or his family members, neighbors or other witnesses shall be present. 3. When searching, the property of the searched person shall not be damaged without reason. Personal privacy found in the search that has nothing to do with the case shall not be made public. 4. The search shall be in written form, signed or sealed by the investigator and the searched person or their families, neighbors or other witnesses. If the searched person or his family is at large or refuses to sign or seal, it shall be indicated in the record. What needs to be clear is that the search must be handled within the relevant procedures of legal trial. If the criminals' homes are searched at will, it will inevitably lead to illegal acts of law enforcement. The parties may file an administrative reconsideration or bring a lawsuit directly to the judicial organ in accordance with relevant laws and regulations to safeguard their legitimate rights and interests.
