After the first trial, the same case was protested by the procuratorate. Is it necessary to sentence it to probation and re-enter the prison for the second trial?

1. The local people's procuratorates at all levels think that the criminal judgments and rulings of the people's courts at the same level are indeed wrong and lodge a protest with the people's court at the next higher level. Procuratorates at all levels believe that there is an error in the judgment or ruling of the court at the same level that has not yet taken effect in the first instance, and lodge a protest with the court at the next higher level through the court of first instance, and send a copy of the protest to the procuratorate at the higher level to prevent the judgment or ruling of first instance from taking effect.

2. The first trial was suspended, and the procuratorate protested and waited for the second trial. A trial will never take effect, which is a compulsory measure. If it is bail or bail, if it is arrest or arrest. If you are arrested, you should be sent back to prison.
