registered dealer on the files of the Revenue, the claim of the assessee for refund could not be rejected nor delayed. Revenue in the said case did not deny, as a matter of fact, that the assessees vendors are all registered dealers on the files of the Revenue and the assessee had also given the TIN number of these vendors. When such particulars are available, it is for the Revenue to take necessary action against the vendors, who had not remitted tax collected by them to the State. Without taking recourse to that, the Revenue could not deny the claim of the assessee. Going by Rule10(2) of TN Vat Rules read along with section 19(1) of the TN Vat Act, it is clear that so long as the purchasing dealer has complied with the requirements as given under Rule 10(2), the claim of the purchasing dealer cannot, by any length of reasoning, be denied by the Revenue. The mere fact that the Revenue had not made an assessment on the assessees vendor, per se, cannot stand in the way of the assessing officer considering the claim of the assessee under section 19 of the Tamil Nadu Value Added Tax Act. A reading of the circular issued by Commissioner along with the provisions of the Act makes it clear that there is nothing repugnant in the said circular issued by the Commissioner as a head of the Department as regards the provisions of the Act on input-tax credit claim. Holding so, allowed the writ petition.
