Advance ruling procedure: streamlined application process with prescribed form, quadruplicate filing, fee and a thirty day withdrawal window.
Clause 383 establishes a streamlined procedure for advance rulings: applications must state the specific question and be filed in the prescribed form and manner in quadruplicate, accompanied by a prescribed fee, and may be withdrawn within thirty days. The clause retains core procedural features of the prior regime but omits transitional and legacy transfer or opt-out provisions, leaving form, fee, and certain consequences of withdrawal to subordinate rules.
