Article 91 of the Criminal Procedure Law stipulates that if a public security organ deems it necessary to arrest a detained person, it shall submit it to the people's procuratorate for examination and approval within three days after detention. Under special circumstances, the approval time can be extended by one to four days. For major suspects who commit crimes on the run, commit crimes many times or commit crimes in collusion, the time for submitting for examination and approval may be extended to 30 days. The people's procuratorate shall, within seven days after receiving the approval letter from the public security organ, make a decision on whether to approve or disapprove the arrest. If the people's procuratorate does not approve the arrest, the public security organ shall immediately release it after receiving the notice and promptly notify the people's procuratorate to execute it. Those who need to continue the investigation and meet the conditions of obtaining a guarantor pending trial or residential surveillance shall be granted a guarantor pending trial or residential surveillance according to law.
Article 34 of the Criminal Procedure Law stipulates that a criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or takes compulsory measures. During the investigation, only lawyers can be entrusted as defenders. The defendant has the right to entrust a defender at any time, and the investigation organ shall inform the criminal suspect of the right to entrust a defender when interrogating the criminal suspect for the first time or taking compulsory measures against the criminal suspect. The people's procuratorate shall, within three days from the date of receiving the case materials transferred for examination and prosecution, inform the criminal suspect that he has the right to entrust a defender.
The people's court shall, within three days from the date of accepting the case, inform the defendant of the right to entrust a defender. If a criminal suspect or defendant requests to entrust a defender while in custody, the people's court, the people's procuratorate and the public security organ shall promptly convey it. After the suspect was arrested, the case continued to add evidence. After the investigation stage, the prosecution stage and the trial stage, the punishment for the criminal suspect is finally determined, and then it is executed in the detention center or prison according to the sentence that the criminal suspect needs to execute.
