Illegal. The Criminal Procedure Law clearly stipulates that Article 33 a criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or compulsory measures are taken. During the investigation, only lawyers can be entrusted as defenders. The defendant has the right to entrust a defender at any time.
According to the above provisions, a criminal suspect may entrust a lawyer to intervene in the case from the date of first interrogation or compulsory measures. Therefore, lawyers can complain to their superiors about their rights protection.
