(1) Where a dealer is a firm or an association of persons or a Hindu undivided family, and such firm, association or family has discontinued business--
         (a) the tax payable under this Act, by such firm, association or family up to the date of such discontinuance may be assessed as if no such discontinuance had taken place; and
         (b) every person who was at the time of such discontinuance a partner of such firm, or a member of such association or family, shall, notwithstanding such discontinuance, be liable jointly and severally for the payment of tax assessed and penalty imposed and payable by such firm, association or family, whether such tax (including any penalty) has been assessed prior to or after such discontinuance, and subject as aforesaid, the provisions of this Act shall, so far as may be, apply as if every such person or partner or member were himself a dealer:
     Provided that where the partner of a firm liable to pay such tax (including any penalty) dies, the provisions of sub-section (4) shall, so far as may be, apply.
     (2) Where a change has occurred in the constitution of a firm or association, the partners or members of the firm or association as it existed before and as it exists after its re-constitution, shall, without prejudice to the provisions of section 34, jointly and severally be liable to pay any tax (including any penalty) due from such firm or association for any period before its re-constitution.
     (3) The provisions of sub-section (1) shall, so far as may be, apply where the dealer, being a firm or association of persons, is dissolved or where the dealer, being a Hindu undivided family, has effected partition with respect to the business carried on by it and accordingly references in that sub-section to discontinuance shall be construed as references to dissolution or, as the case may, to partition.
     (4) Where a dealer liable to pay tax under this Act dies, than--
         (a) if the business carried on by the dealer is continued after his death by his legal representative or any other person, such legal representative or other person, shall be liable to pay the tax (including any penalty) due from the dealer under this Act, whether such tax (including any penalty) has been assessed before his death but has remained unpaid, or is assessed after his death;
         (b) if the business carried on by the dealer is discontinued after his death, his legal representative shall be liable to pay out of the estate of the deceased, to the extent the estate is capable of meeting the charge, the tax (including any penalty) due from the dealer under this Act, whether such tax (including any penalty) has been assessed before his death but has remained unpaid, or is assessed after his death,
     and the provisions of this Act shall, so far as may be, apply to such legal representative or other person as if he were the dealer himself.
