Final answer:
The Idaho Real Estate Commission does not investigate actions related to the exploration for minerals on state lands or the regulation of securities and associated brokers, as these responsibilities are handled by other entities.
Step-by-step explanation:
The Idaho Real Estate Commission may investigate a person engaged in the real estate business or acting as a real estate broker or salesperson within the state of Idaho for several reasons, but there are certain actions that fall outside its jurisdiction. These include overseeing the exploration for oil, gas, and other minerals on state lands—a responsibility that generally falls to the commissioner of the General Land Office who also serves as the chairman of boards in charge of such matters.
Additionally, the regulation and supervision of the sale of securities and the brokers, dealers, and bankers who sell them is not typically under the purview of a real estate commission but rather under state or federal financial regulatory authorities.
