(1) If the whole or any portion of a penalty is not paid by the date by which it is required to be paid, the unpaid balance from time to time carries interest at the statutory rate. (2) Where an application has been made under paragraph 16A(8) or 16C(8), the penalty is not required to be paid until the application has been determined, withdrawn or otherwise disposed of. (3) If a portion of a penalty has not been paid by the date required for it, the enforcer to whom it is payable may, where it considers it appropriate to do so, require so much of the penalty as has not already been paid (and is capable of being paid immediately) to be paid immediately. (4) Where on an appeal under paragraph 16D the appropriate court substitutes a penalty of a different nature or of a lesser amount, the court may require the payment of interest at the statutory rate on the substituted penalty from whatever date it considers appropriate (which may include a date before the determination of the appeal).
