Different tasks: prosecutors exercise their rights on behalf of the state, act as prosecutors in criminal cases, and prosecute criminal suspects on behalf of the state and society; Another role is to act as a supervisor of the law and supervise judicial activities. Lawyers are entrusted by the parties to participate in various lawsuits as agents, and only use their legal knowledge to provide legal services to the parties. 3.

Article 31 When acting as a defender, a lawyer shall, according to facts and laws, put forward materials and opinions on acquittal, lighter punishment or reduction or exemption of criminal responsibility of criminal suspects and defendants, so as to protect the litigation rights and other legitimate rights and interests of criminal suspects and defendants.
