Legal analysis: A criminal sentenced to public surveillance, criminal detention, fixed-term imprisonment or life imprisonment may have his sentence reduced if he consciously abides by prison regulations, receives education and reform, shows genuine repentance, or performs meritorious service. Those who have made one of the following major meritorious deeds shall have their sentences reduced. The term actually executed after commutation shall not be less than the following period: (2) If a person is sentenced to life imprisonment, it shall not be less than 13 years. Article 81 A criminal sentenced to fixed-term imprisonment shall be sentenced to more than half of the original sentence, and a criminal sentenced to life imprisonment shall be released on parole if he earnestly abides by prison regulations, receives education and reform, and does show repentance and is not in danger of recidivism. If there are special circumstances, with the approval of the Supreme People's Court, the above penalty execution restrictions may not be imposed.
Legal basis: Article 241 of the Criminal Procedure Law of People's Republic of China (PRC), the parties and their legal representatives and close relatives may appeal to the people's court or the people's procuratorate against the legally effective judgment or ruling, but they cannot stop the execution of the judgment or ruling. If there are no specific provisions in the law, you can apply to that court for retrial, to the court of first instance and second instance, or to the provincial high court for retrial. From the point of view of maintaining the res judicata of the court's judgment, the probability of changing the judgment is not great, but it is not impossible. According to the laws of our country, there is no penalty for appeal, and there is no penalty for applying for retrial or appeal. Don't worry about that. However, during the appeal, the prison did not consider the issue of commutation.
