undertaking expansion were to be given the benefit of an interstate free deferral scheme for a period of five years. Accordingly, an agreement was executed for the purpose of implementation of the said deferral scheme. While so, a notice was issued to the petitioner inviting objections stating that the petitioner is not eligible to avail deferral for the period from April 2002 to June 2002. The petitioner vide letter dated 22.12.2006 stated that there is no specific condition as alleged by the respondent and the only stipulation to claim the benefit of deferral of sales tax is that the base volume and base sale value have to be reached in that year and they have crossed the base production volume and sale value and requested to drop the proposal of levying interest under Section 24 (3) of the TNGST Act. The reply was examined and found to be not acceptable, since as per Eligibility Certificate, the petitioner has reached the base production and base sale value during July 2002 only, but has availed deferral from April 2002 onwards. Hence the impugned orders came to be passed. Challenging the same, these writ petitions have been filed by the petitioner.
