Can the prison spend money to reduce the sentence?

According to the relevant provisions of the Criminal Law, if a prisoner does repent or perform meritorious service during his sentence, his sentence may be reduced; Those who have made significant meritorious service shall have their sentences reduced. The commutation or parole of a prisoner sentenced to fixed-term imprisonment or commuted to fixed-term imprisonment shall be recommended by the prison and submitted to the intermediate people's court in the place where the prisoner served his sentence for a ruling. The commutation of a prisoner sentenced to death with a two-year suspension of execution, and the commutation and parole of a prisoner sentenced to life imprisonment shall be proposed by the prison, and shall be submitted to the higher people's court of the place where the prisoner served his sentence for a ruling after being examined and approved by the prison administration of the province, autonomous region or municipality directly under the Central Government. Criminals sentenced to public surveillance, criminal detention, fixed-term imprisonment or life imprisonment may have their sentences reduced if they consciously abide by prison regulations, receive education and reform, and truly show repentance or render meritorious service during the execution period; Those who have made one of the following major meritorious deeds shall be given a reduced sentence, including: preventing others from engaging in major criminal activities, reporting major criminal activities inside and outside the prison, being verified through investigation, having made inventions or making major technological innovations; Other major contributions to the country and society, and so on. If the sentence actually executed after commutation is sentenced to public surveillance, criminal detention or fixed-term imprisonment, it shall not be less than half of the original sentence; Life imprisonment shall not be less than thirteen years. As for how long can the sentence be reduced after imprisonment? The law is not clear, so prisoners can raise it at any time, but it needs to be studied and decided by the prison management department. Legal basis: Article 79 of the Criminal Procedure Law of People's Republic of China (PRC) stipulates that the executing organ shall submit a proposal for commutation to the people's court at or above the intermediate level. When trying a case, the people's court shall form a collegial panel, and if there are facts of repentance or meritorious service, it shall make a ruling to reduce the sentence. Without legal procedures, the sentence may not be reduced. "Provisions on Working Procedures for Prison Petition for Commutation and Parole" Article 6 A prison's application for commutation and parole shall be decided by the collective research of the people's police in the prison area with or without a sub-prison area, the review of the warden's office meeting, the review of the prison penalty enforcement department, the review of the prison commutation and parole review committee and the warden's office meeting. The penalty execution departments of the prison administrations of provinces, autonomous regions and municipalities directly under the Central Government shall, in accordance with legal procedures, review the suggestions on commutation and parole submitted by prisons and issue opinions, report them to the deputy director in charge for convening the commutation and parole review committee for review, and report them to the director for examination and approval. When necessary, they may convene an office meeting of the director for decision.
