The procuratorial organ’s right to investigate civil cases of civil protest is the purpose of proving whether the effective verdict is illegal or not. It is a necessary prerequisite for performing the duties of legal supervision and is a system guarantee for preventing abuse of power. The scope of investigation by the procuratorial organs in civil protest should be based on the cause of protest.
