What is the authority of a criminal litigation agent?

A, criminal proceedings can entrust several agents ad litem, China's civil procedure law stipulates that the parties and their legal representatives can entrust 0 to 2 people as agents ad litem. The reason why the law stipulates this is, on the one hand, to consider the needs of litigation and respect the parties' expression of will; On the other hand, it also limits the number of entrusted agents, which neither affects the parties' exercise of litigation rights, but also facilitates litigation procedures. There are different regulations on the number of entrusted agents in foreign countries, such as 1 in France. The United States, Japan and Hungary have no restrictions on the number of entrusted agents. In the United States, in major cases, the original defendant can organize a lawyer group. Hungary stipulates that in the case of entrusting an agent, any agent can conduct litigation alone, but each litigation can only be conducted by one agent. If the statements of several agents are inconsistent with the litigation behavior, the people's court may determine that the statements of the parties are inconsistent with the litigation behavior. Two. According to the provisions of China's Criminal Procedure Law, victims of public prosecution cases, private prosecutors of private prosecution cases, plaintiffs and defendants of criminal incidental civil actions, and complainants of criminal appeal cases may entrust agents to participate in the proceedings according to law. An agent in criminal proceedings may be a lawyer or a citizen other than a lawyer. However, the person subjected to execution or a person deprived of or restricted in personal freedom according to law cannot act as an agent. There are two kinds of agency in criminal proceedings: one is legal agency. Legal agency is an agency based on legal provisions. The second is entrusted agency. Principal-agent is an agent based on the entrustment and authorization of the principal. Different agents ad litem have different scopes, rights and obligations. But they also have something in common. Specifically, all agents must carry out activities within the scope of agency authority; The litigation behavior of the agent within the scope of authorization has the same legal effect as the client's own litigation behavior; The legal consequences of the agent's legal representation shall be borne by the principal. The agent in criminal proceedings participates in the proceedings in the name of the client rather than in his own name. An agent must protect his legitimate rights and interests through litigation according to the will of the principal. At the same time, the agent ad litem must conduct the litigation within the scope authorized by the principal, and the principal will not bear the consequences of the litigation activities beyond the scope authorized without the ratification of the principal. The principal has the right to change the entrusted content or revoke the agency right, and the agent may also refuse the agency according to law, resulting in the change or revocation of the agency authority. Article 29 of China's "Lawyers Law" clearly stipulates that the client may refuse the lawyer to continue to represent him or entrust another lawyer to represent him. After accepting the entrustment, a lawyer may not refuse to represent him without justifiable reasons, but if the entrusted matter is illegal, the client engages in illegal activities by using the services provided by the lawyer, or the client conceals the facts, the lawyer has the right to refuse to represent him. Where the power of agency is changed or revoked, it shall promptly notify the people's court with jurisdiction in writing. During the litigation, after the dissolution of the agent, the people's court shall allow the client to appoint another agent. However, if the case has been handled by collegiate bench, it is generally not appropriate to change the entrustment.
