3. It is contended that Section 9(2) empowers the authorities under the general tax enactment to assess, re-assess, collect and enforce payment of any tax under the CST Act, exercising the powers available to them under the general sales tax law of the appropriate State and so carry out the provisions of the CST Act on behalf of the Government of India. In so carrying out the functions under the CST Act, the provisions under the general sales tax laws of the State, including provisions relating to returns, provisional assessment and so on and so forth, shall apply accordingly. It is the contention of the learned Counsel for the petitioner that the provisions of the general sales tax laws applicable, underwent a drastic change, on the introduction of the Kerala Value Added Tax Act, 2003 [for brevity "KVAT Act"]. This is insofar as The KVAT Act providing for a self assessment under Section 21, on the return being filed in the proper form with the prescribed documents. Hence, under the KVAT Act, there is only provision for a re-assessment under Section 25(1). There is no question of an assessment as such.
