The “beauty contest” method requires interested parties to submit proposals on how they intend to use the spectrum. A committee of the spectrum regulating agency then decides which of the proposals better serves public goals. This method relies on the objectivity, independence, technical proficiency and honesty of the members of the deciding committee, which are not always guaranteed.
In many countries there are rules for spectrum adjudication that call for relinquishing spectrum bands that have been acquired but are not being used. Enforcement, however, is often lacking due to strong economic interests.
