In case a person who got a benefit of postponement of collection in accordance with Article 7 has failed to pay the national tax and disposal charges of delinquency of which collection was postponed, by the due date of payment or in case the Government collects the tax and charges in accordance with the preceding paragraph, if there is any security procured concerning the national tax and disposal charges of delinquency to be collected, the Government shall dispose such security in the same manner as in the case of disposal of delinquency to appropriate for the amount of national tax, disposal charges of delinquency to be collected and expenses for the disposition, or let the guarantor pay the national tax and disposal charges of delinquency to be collected. In this case, if the value of security is insufficient for the amount of national tax and disposal charges of delinquency to be collected and expenses for disposition of such security, the disposal of delinquency shall be made on other property of taxpayer, and if his guarantor fails to pay the amount to be collected in full, the disposal of delinquency shall be made upon the taxpayer's property and if there still remain some deficits or the disposal of delinquency does not cover the deficit, the disposal of delinquency shall be made on the property of the guarantor.
