1. During the period of criminal detention, lawyers were not invited, and the criminal suspects could not be met, and the family members could not know the case in time;
2. If a defense lawyer holds a lawyer's practice certificate, a law firm's certificate and a power of attorney or a letter of legal aid to meet with the criminal suspect or defendant in custody, the detention center shall arrange the meeting in time, which shall not exceed 48 hours at the latest. The main functions of lawyers in criminal detention are:
(1) For criminal suspects during criminal detention, only lawyers can meet the suspects, but family members cannot visit them. In order to strive for the greatest rights and interests, it is necessary to ask lawyers to intervene to understand the case;
(2) Entrusted lawyers can provide legal advice and represent complaints and accusations. According to the law, lawyers can provide legal advice to criminal suspects when they are first interrogated or meet with them after compulsory measures are taken. Due to the special identity and status of criminal suspects and the lack of legal knowledge, criminal suspects often dare not boldly safeguard their legitimate rights and interests because they don't know the law;
(3) Lawyers can apply for bail pending trial on their behalf, and apply for cancellation or change of compulsory measures on their behalf. After the criminal suspect is arrested, in order to solve the case quickly, the interrogators may not always carry out the interrogation in strict accordance with the law, which may damage the legitimate rights and interests of the criminal suspect and even seriously infringe on the personal rights of the criminal suspect.
Legal basis: Article 34 of the Criminal Procedure Law of People's Republic of China (PRC).
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 takes compulsory measures; During the investigation, only lawyers can be entrusted as defenders. The defendant has the right to entrust a defender at any time.
When interrogating a criminal suspect for the first time or taking compulsory measures against him, the investigation organ shall inform him that he has the right to entrust a defender. The people's procuratorate shall, within three days from the date of receiving the case materials transferred for examination and prosecution, inform the criminal suspect that he has the right to entrust a defender. The people's court shall, within three days from the date of accepting the case, inform the defendant of the right to entrust a defender. If a criminal suspect or defendant requests to entrust a defender while in custody, the people's court, the people's procuratorate and the public security organ shall promptly convey it.
If a criminal suspect or defendant is in custody, his guardian or near relative may also entrust a defender.
After accepting the entrustment of a criminal suspect or defendant, the defender shall promptly inform the case-handling organ.
