Advance ruling procedure requires admission, hearing and written pronouncement, with reasons required for any rejection. The provision sets out the Authority's procedure on receipt of an advance ruling application: forward the application to the concerned officer and call for records; after examining records and hearing both parties, admit or reject the application with reasons if rejected; where admitted, examine further material, provide hearing opportunities, and pronounce a written advance ruling within the prescribed time; if members differ, state points of difference and refer to the Appellate Authority; send certified copies of orders and rulings to the applicant, concerned officer and jurisdictional officer.
