Why did the criminal suspect not receive the indictment from the procuratorate or the court when all the criminal cases were in court? If the criminal suspect or defendant you mentioned went to court for trial, but no indictment was actually received. This is a serious violation of procedures and is basically impossible in reality. Therefore, there may be only one situation, that is, the criminal suspect was initially subject to compulsory measures, but later, based on in-depth investigation and the facts of the case, the procuratorate did not prosecute him or hold him criminally responsible, so there is no need to serve him with an indictment. .
