Penalty reduction option under section 11AC must be stated in adjudication orders so assessees are informed. The first and second provisos to section 11AC provide a reduced-penalty incentive for prompt payment of duty and interest; because this operates as an option available to the assessee, the Board requires that every adjudication Order-in-Original imposing penalty under section 11AC must mandatorily state the provisions of those provisos so the assessee is informed of the reduced-penalty alternative and the conditions for claiming it.
