(1) The designated authority shall, within a period of fifteen days from the date of receipt of the declaration, by order, determine the amount payable by the declarant in accordance with the provisions of this Act and grant a certificate to the declarant containing particulars of the tax arrear and the amount payable after such determination, in such form as may be prescribed.
     (2) The declarant shall pay the amount determined under sub-section (1) within fifteen days of the date of receipt of the certificate and intimate the details of such payment to the designated authority in the prescribed form and thereupon the designated authority shall pass an order stating that the declarant has paid the amount.
    (3) Every order passed under sub-section (1), determining the amount payable under this Act, shall be conclusive as to the matters stated therein and no matter covered by such order shall be reopened in any other proceeding under the Income-tax Act or under any other law for the time being in force or under any agreement, whether for protection of investment or otherwise, entered into by India with any other country or territory outside India.
     Explanation.--For the removal of doubts, it is hereby clarified that making a declaration under this Act shall not amount to conceding the tax position and it shall not be lawful for the income-tax authority or the declarant being a party in appeal or writ petition or special leave petition to contend that the declarant or the income-tax authority, as the case may be, has acquiesced in the decision on the disputed issue by settling the dispute.
