Can a civil servant with a lawyer's qualification certificate appear as a lawyer in criminal cases and conduct legal defense?

To be a lawyer, you need to pass the national judicial qualification examination first, and then get a lawyer's practice license after internship in a law firm. The law forbids civil servants to be lawyers. Defenders in criminal cases can be the following three kinds of people: 1. Lawyer. 2. Recommended by people's organizations and defendant units. Because the current team of lawyers in our country can not fully meet the actual needs, in order to effectively safeguard the legitimate rights and interests of criminal suspects and defendants, mass organizations such as trade unions, women's federations, student unions, and the units where criminal suspects and defendants work can recommend citizens to be defenders of criminal cases. 3. Guardians, relatives and friends of criminal suspects and defendants may also accept the entrustment of criminal suspects and defendants to act as their defenders. In fact, the revised Criminal Procedure Law has expanded the range of options for criminal suspects and defendants to entrust defenders, because all relatives and friends except guardians can accept the entrustment of criminal suspects, defendants and their legal representatives as defenders. This is very beneficial for criminal suspects and defendants to entrust defenders in time, solve the problem of difficulty in hiring lawyers in time and effectively, and safeguard their legitimate rights and interests. So the situation you are talking about may be that civil servants defend the defendant as relatives and friends. Furthermore, in-service civil servants in public security prisons must be close relatives or guardians of the accused to act as defenders, and other relatives are not allowed.
