    (13) Where the amount as modified by the appellate authority or tribunal or court is more than the amount determined under sub-section (10) by the Central Excise Officer, the time within which the interest or penalty is payable under this Act shall be counted from the date of the order of the appellate authority or tribunal or court in respect of such increased amount.
     (14) Where an order determining the duty of excise is passed by the Central Excise Officer under this section, the person liable to pay the said duty of excise shall pay the amount so determined along with the interest due on such amount whether or not the amount of interest is specified separately.
