Legal analysis: after the criminal suspect is questioned for the first time or taken compulsory measures. The reasons are as follows: First, after the suspect was arrested, he was completely in a passive position. Second, most of the suspects were arrested in the absence of their family members, who were still in the dark before the case handlers issued a notice. I don't even believe that people I love will commit crimes. As for the true situation of the case, I know nothing about it. Third, when the suspect is arrested, his family should immediately hire a lawyer for him. With the timely consultation of the lawyer, the suspect will be clear-headed. Fourth, according to the regulations, lawyers can file charges and accusations on their behalf when meeting with criminal suspects.
Legal basis: Article 33 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.
