# 604.17 Purpose.

The purpose of this subpart is to set out the requirements for requesting an advisory opinion from the Chief Counsel's Office. An advisory opinion may also request that the Chief Counsel issue a cease and desist order, which would be an order to refrain from doing an act which, if done, would be a violation of this part.
