Probation is a relatively light criminal punishment. For probation, he can't be at fault when executing it. If there are some corresponding mistakes, he will revoke the probation. 1. When will the ruling on revocation of probation take effect? Revoking probation means that probation is no longer applied, the original sentence is executed or the penalty that should be executed is re-decided. According to the provisions of Article 77 of the Criminal Law, the revocation of probation and the handling of criminals after revocation of probation are divided into two situations: 1: If a criminal who has been declared suspended commits a new crime within the probation period of probation or finds that there are other crimes that have not been decided before sentencing, the probation shall be revoked. In this case, if a new crime or a newly discovered crime is sentenced, the punishment for the former crime and the latter crime shall be determined in accordance with the provisions of Article 69 of the Criminal Law on combined punishment for several crimes. The criminal law has no special provisions on newly committed crimes and newly discovered crimes. It should be understood that no matter what the nature of the newly committed crime and the newly discovered crime is, whether the crime is light or heavy, whether it is intentional crime or negligent crime, the probation should be revoked and handled according to the principle and method of combined punishment for several crimes. Of course, the newly decided penalty can no longer be suspended. 2. If a criminal who has been declared on probation violates laws, administrative regulations or the provisions of the public security department of the State Council on the supervision and administration of probation, and the circumstances are serious enough not to constitute a crime, his probation shall also be revoked and the original sentence shall be executed. The purpose of this provision is to solve the legal basis for putting those suspended criminals in prison to execute the original sentence in practice, so as to urge criminals to abide by the law and effectively accept reform during the probation period. Two. Cases in which probation is not applicable 1. Infringement of intellectual property rights constitutes a crime again after criminal punishment or administrative punishment. Crimes against intellectual property rights mainly include: the crime of counterfeiting registered trademarks, the crime of selling goods with counterfeit registered trademarks, the crime of illegally manufacturing and selling goods with illegally manufactured registered trademarks, the crime of counterfeiting patents, the crime of infringing copyrights, the crime of selling infringing copies, and the crime of infringing trade secrets. 2. The definition of "repentance performance" without repentance performance is characterized by surrender or meritorious service; Although it does not have the plot of surrender, it can truthfully confess the main criminal facts; Actively apologize to the victim and return the stolen goods and compensation; Abide by the relevant provisions during the period of bail pending trial, and cooperate with case handling and assistance and education; Other circumstances with penitence. Failure to repent shows that the defendant does not meet the above situation. 3. Refusing to hand over illegal income refers to the economic benefits directly obtained by the actor due to criminal violations, which should be recovered or ordered to make restitution in accordance with the provisions of the Criminal Law, and the fruits arising therefrom. If the perpetrator turns it in, it means that the guilty attitude is good. 4. Other circumstances in which probation is not applicable.
