(9)Where in the assessment or re-assessment of a dealer for any assessment year, any assessing authority, -

(a) has included any turnover and any superior authority or Court has, in exercise of the powers lawfully vested in it, held such turnover to relate to the assessment of-

(i) such dealer for any other assessment year, or

(iii) any other dealer, whether under this Act, or under the Central Sales Tax Act, 1956,

(b) has not included any turnover on the ground that it relates to assessment under the Central Sales Tax Act, 1956 and any superior Authority or Court has, in exercise of the powers lawfully vested in it, held such turnover to relate to the assessment of that dealer under this Act, whether for such assessment year or any other assessment year, then nothing contained in this section limiting the time shall apply to assessment or re-assessment whether under this Act or under the Central Sales Tax Act, 1956 of such dealer or such other dealer, relating to such assessment year or such other assessment year, as the case may be.
