That is, the people's procuratorate supervises the legality of the investigation activities of public security organs. According to the constitution of our country, the people's procuratorate exercises the power of investigation and supervision, aiming at giving play to the role of mutual restraint between procuratorial organs and public security organs, ensuring accurate and legal investigation of crimes, and preventing and reducing the occurrence of unjust, false and misjudged cases.

The main contents of investigation and supervision include:

(1) Whether the legal procedures of the public security organs in the investigation activities are complete, and whether there are illegal arrests, false arrests and omissions in arresting criminals.

(two) filing, investigation, preliminary examination, inspection, search, seizure and identification of whether there is any illegal act.

(3) Whether there are violations of law and discipline, extorting confessions by torture, etc. Interrogate defendants and witnesses.

The people's procuratorate carries out investigation and supervision, which is mainly combined with the examination of arrest and prosecution. If the above-mentioned illegal acts are found, they shall promptly put forward rectification opinions to the public security organs; If the circumstances are serious enough to violate the criminal law, legal responsibilities shall be investigated according to law.

Extended data

Investigation and supervision is an important part of the legal supervision of criminal proceedings of the people's procuratorate, which is of great significance in criminal proceedings.

(a) investigation and supervision is conducive to ensuring the unified and correct implementation of the national criminal law and ensuring the quality of handling cases.

The supervision of the people's procuratorate on the legality of investigation activities can enable the investigation organs to find and effectively correct the illegal acts in the investigation activities in time, thus ensuring that the investigation activities are carried out in strict accordance with legal procedures and requirements.

Ensure that criminals are investigated promptly, accurately and legally from the litigation procedure, ensure the unified and correct implementation of the national criminal law, prevent and avoid unjust, false and wrong cases, and ensure the quality of cases.

(two) investigation and supervision is conducive to safeguarding the legitimate rights and interests of citizens (criminal suspects and defendants)

Judicial practice has proved that in investigation activities, illegal methods such as extorting confessions by torture, inducing confessions, cheating confessions or illegal detention are used instead of collecting evidence according to legal procedures and requirements, which will seriously damage citizens' democratic rights and other legitimate rights and interests.

Therefore, if people's procuratorates exercise legal supervision over investigation activities, they can find, stop and correct the above-mentioned illegal acts in time and earnestly safeguard the legitimate rights and interests of citizens.

(3) Investigation and supervision is conducive to improving the law enforcement level of investigators, urging them to act in strict accordance with the law and better safeguarding the authority of the socialist legal system.

Through investigation and supervision, the people's procuratorates promptly correct the illegal acts of abuse of power by investigators, urge investigation organs to conscientiously sum up experiences and lessons, and improve their understanding and law enforcement level in handling cases strictly according to law.

At the same time, through investigation and supervision, we can promptly correct violations of law and discipline in investigation activities, improve our understanding of the fairness and legality of handling cases by public security and judicial organs, and thus better safeguard the authority of the socialist legal system.
