What is the purpose of establishing the designated defense system in criminal procedure law?

In criminal proceedings, the purpose of establishing the appointed defense system is to protect the defendant's right to criminal defense, which is also a manifestation of China's protection of human rights.

According to the provisions of China's Criminal Procedure Law, if the defendant who commits a juvenile crime, a deaf-mute crime or is likely to be sentenced to death does not entrust a defender himself, the court shall appoint a defense lawyer to defend him through the local legal aid center.
