Lawyers play a very important role in public prosecution cases.

It can be said with great certainty that lawyers play a very important role in criminal cases, and it is very necessary to hire professional criminal defense lawyers to provide help for criminal suspects or defendants. In the investigation stage, lawyers can meet with criminal suspects to relieve their anxiety, give psychological comfort and explain the alleged charges and related legal knowledge to the criminal suspects, so that the criminal suspects can know whether they constitute a crime or the possible consequences, which can largely avoid the occurrence of extorting confessions by torture, and can help the criminal suspects to apply for bail pending trial according to the circumstances. In the stage of examination and prosecution, we can get a deeper understanding of the case from the examination organ of the procuratorate, including consulting or copying all the case files, and put forward the defense opinions of the criminal suspect to the procuratorate, which are innocent, light and heavy. At the trial stage, lawyers can meet with the defendant, understand and collect evidence clues of light or innocent crimes, meet with the presiding judge, consult and copy the case files, conduct real research on the defendant's guilty cases, and conduct court debates. article 3 of the criminal procedure law of People's Republic of China (PRC) stipulates that the public security organs shall be responsible for investigating, detaining, arresting and pre-examining criminal cases. The people's procuratorates shall be responsible for cases of prosecution, approval of arrest, investigation and public prosecution directly accepted by procuratorial organs. The people's court shall be responsible for the trial. Except as otherwise specified by law, no other organ, organization or individual has the right to exercise these powers.
