Yes, but the best time for lawyers to intervene in criminal proceedings should be in the investigation stage, especially the day when the suspect is first questioned or compulsory measures are taken. The earlier the role, the better. According to the relevant provisions of the Criminal Procedure Law, a criminal suspect may hire a lawyer to provide him with legal advice, appeal and accusation on his behalf after being interrogated for the first time by the investigation organ or from the date when compulsory measures are taken. After the criminal suspect is arrested, the lawyer hired can apply for bail pending trial. The entrusted lawyer has the right to know the charges charged by the criminal suspect from the investigation organ, and can meet the criminal suspect in custody and learn the case from the criminal suspect. If a criminal suspect is extorted by torture or detained for an extended period of time, the entrusted lawyer may appeal and accuse him on his behalf.
