How long is the criminal detention based on the letter of understanding?

Legal analysis:

In criminal cases, the letter of understanding also plays a great role, which can reduce the crime of the parties, because the final judgment is made by the court, and the cycle of criminal cases is relatively long, usually taking more than five months, and cases involving a large amount of money and a large number of people may be delayed. But it also depends on the specific case and the case. A letter of understanding is a plot to mitigate the crime of the parties, and there are other plots. According to various cases, there are specific circumstances such as returning stolen goods, making meritorious deeds, pleading guilty, and actively cooperating with the investigation. Moreover, once a criminal case is detained, the family members can't contact the parties, so they can only entrust a lawyer to see the parties to understand the case. Therefore, it is highly recommended to entrust a lawyer to handle it. In the early stage, bail will be won for the parties, and the circumstances of the case will be lighter. Later, we will strive for the legitimate rights and interests of the parties in sentencing, probation or even non-prosecution. If the public security organ deems it necessary to arrest the 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 release it immediately after receiving the notice and notify the people's procuratorate of the situation in time. If it is necessary to continue the investigation and meet the conditions for obtaining a bail pending trial, it shall be released on bail pending trial or under residential surveillance according to law.

Legal basis:

Article 91 of the Criminal Procedure Law of People's Republic of China (PRC), if the 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.

Derivative problem:

How long can the letter of understanding be issued?

1. Obtaining the victim's understanding is only a reference for sentencing. 2. Reconciliation and understanding have been reached. If the circumstances are not serious, criminal cases will not be handled, so the influence of understanding is still great. 3, after understanding, the judicial organs can be given a lighter, mitigated or exempted from criminal punishment. If it is handled, it shall be decided by the judicial organ according to the case. Therefore, when and whether to release the personnel should also be decided by the judicial organs.
