A defense lawyer refers to a lawyer who provides defense for the defendant in criminal proceedings, and a lawyer who provides legal services for other parties cannot become a defense lawyer. In criminal proceedings, the lawyer of the victim in a public prosecution case and the lawyer of the plaintiff in a private prosecution case can only be called a criminal agent. Lawyers hired in civil cases are called entrusted agents. The defense range is very small.
In criminal proceedings, defense lawyers are usually staff members of procuratorial organs and private prosecutors in private prosecution cases. In addition, the defender has great rights, which are independent of the defendant's right to defend, and are greater than the agency authority, but they are basically to protect the interests of their clients.
