Sec. 1.1  Proceedings before the Commission.

    The Commission may on its own motion or petition of any interested 
party hold such proceedings as it may deem necessary from time to time 
in connection with the investigation of any matter which it has power to 
investigate under the law, or for the purpose of obtaining information 
necessary or helpful in the determination of its policies, the carrying 
out of its duties or the formulation or amendment of its rules and 
regulations. For such purposes it may subpena witnesses and require the 
production of evidence. Procedures to be followed by the Commission 
shall, unless specifically prescribed in this part, be such as in the 
opinion of the Commission will best serve the purposes of such 
proceedings.
