Section 5Sec./Art. 5

The National Telecommunications Commission, on reasonable notice to the grantee, may at any time change, cancel or modify, in whole or in part, any or all of the allotments of frequencies or wavelengths on the following grounds:

a. Such frequencies or wavelengths have been used, or there is danger that they will be used by the grantee to impair electrical communications, or to stifle competition, or to obtain a monopoly in electrical communications or to secure unreasonable rates for such communications or to violate the laws or public policies of the government; and

b. When public interest requires that such frequencies or wavelengths be used for other purposes than those of the grantee, either by the government or other individuals or corporation authorized by it.
