Regulatory Publications

​​​​​​The legal framework of ITU comprises the basic instruments of the Union, which have treaty status and are binding on ITU Member States. These instruments are the Constitution and Convention of the International Telecommunication Union and the Administrative Regulations, which complement the Constitution and the Convention.

The Radio Regulations (RR) form an integral part of the Administrative Regulations.

The Rules of Procedure are approved by the Radio Regulations Board (RRB). They complement the RR by providing clarification of the application of particular Regulations or establishing the necessary practical procedures that may not be provided for in the current Regulatory Procedures
