Users that apply to the National Communications Commission to coordinate and handle radio frequency interference in accordance with Article 63 of the Act, or declare that an illegally established Radio Station uses the frequency shall, prior to the submission of complaint, determine the source of interference or the location and used frequency of Radio Station; and submit “Radio Frequency Interference and Illegal Use Complaint Form” and relevant documents. The complaint shall be handled in accordance with the following procedures:
1. Complaints concerning interference to military communications shall be accepted, checked and excluded by Ministry of National Defense. Where the source of interference signal cannot be verified, users may contact the National Communications Commission for investigating the source of interference and resolving actions to handle the interference.
2. Complaints concerning interference to non-military communications and interference complaints from overseas shall be accepted, checked and excluded by the National Communications Commission. Where the source of interference signal cannot be verified, users may contact the Ministry of National Defense for resolving actions.

Article 43
Where used radio frequency is interfered, the radio frequency assigned by the competent authority shall be protected.
In cases where interference cannot be eliminated between legal radiocommunications, the competent authority may, upon application, allocate additional radio frequencies for their use.
Where the source of interference is from overseas, the competent authority may request the assistance of the National Communications Commission to conduct interference detection, and shall collect relevant information and handle the issue in accordance with ITU Radio Regulations.

Article 43-1
The principles of the National Communications Commission for handling interference are as follows:
1. Interference occurring between military and non-military radiocommunications shall be coordinated and handled by the Ministry of National Defense and the National Communications Commission.
2. Where the measurement of radio frequency is disputable, the results of measurements undertaken by the National Communications Commission shall be taken as the criterion.
3. Where interference occurs between domestic and foreign users, the National Communications Commission shall coordinate with relevant units to solve the problem if the emission site or interference source is within the country.

Article 45
In the case of interference when using legal radio frequency and no improvement has been made despite the National Communications Commission’s attempt at coordination, the National Communications Commission may order related users to change the time and location of using the radio frequency; adjust the antenna transmission direction and power; or adopt other appropriate methods in accordance with Paragraph 2 of Article 63 of the Act. When necessary, the competent authority may be consulted for assistance.
During the coordination as described in the precedent Paragraph, the National Communications Commission may order the user to cease using the frequency depending on the severity of interference.
