In addition to other requirements of service and notice now imposed by law, a copy of any application, formal complaint, or notice to or issued by the Georgia Public Service Commission shall also be served upon the Consumers' Utility Counsel. The Commission shall not proceed to hear or determine any such petition, complaint or proceeding in which the Public Counsel is entitled to appear unless it shall affirmatively appear that the Public Counsel was given at least ten days' written notice thereof, unless such notice is affirmatively waived in writing or the Public Counsel appears and specifically waives such notice; provided, that once the Commission has begun to hear or determine any such petition, complaint or proceeding of which prior notice was given or waived, the Commission shall thereafter issue such orders and take such action relating thereto as it may deem appropriate, and upon such notice to parties as it may deem appropriate. Whenever service of notice is perfected by mail, four days shall be added to the prescribed period. Proof of service of notice may be made by certificate or other proof satisfactory to the Commission, and shall create a rebuttable presumption of service.
