Can AIC investigate and deal with unfair competition cases of mobile companies?

yes, but you must file a case first.

Filing procedure:

According to the principle of procedural legality, the public security and judicial organs must conduct criminal proceedings in strict accordance with legal procedures, and can't go beyond or reverse any litigation stage at will. Only in this way can the public security and judicial organs handle criminal cases accurately, timely and effectively, and ensure the realization of the tasks and objectives of criminal proceedings. However, due to the different specific circumstances of criminal cases, not every criminal case must go through five stages of litigation. For example, a case of private prosecution does not need to go through the investigation stage, and the victim directly files a lawsuit with the people's court; In other cases, after the people's procuratorate makes a decision not to prosecute, it will be terminated, so there is no need to go through trial and execution procedures; In some cases of public prosecution, if the circumstances of the crime are minor, there is no need to be sentenced to punishment or exempted from punishment according to law. At the stage of examination and prosecution, the people's procuratorate can make a decision not to prosecute, thus ending the proceedings that have already begun. However, any criminal case entering the criminal proceedings must go through the filing stage. Only after filing a case can other litigation stages be carried out in turn, and the investigation, prosecution and trial activities of public security and judicial organs have legal basis and legal effect. Therefore, the filing procedure is a necessary procedure in criminal proceedings.

This is the first case that Mingxi County Administration for Industry and Commerce investigated and dealt with illegal business practices in the communications industry.
