As far as the criminal procedure law is concerned, it is wrong. According to the second paragraph of Article 37 of the Criminal Procedure Law, with the permission of the people's procuratorate or the people's court, the defense lawyer may collect materials related to the case from the victim or his close relatives or witnesses provided by the victim.
As far as the current new lawyer law is concerned, it is correct. The basis is the second paragraph of Article 35 of the new Lawyers Law: if a lawyer investigates and collects evidence on his own, he can investigate the situation related to undertaking legal affairs with the lawyer's practice certificate and the certificate of the law firm.
