consignee has no dealing in cashew kernels. This is the reason for raising the suspicion. Petitioner has produced Exhibit P6 issued by the office of the Value Added Tax Officer, Ward No.28, Department of Trade and Taxes, Delhi certifying that M/s.Aditya sales Corporation, Naya Bazar, New Delhi is a registered dealer of Ward 28, Department of Trade and Taxes, Vyapar Bhavan, I.P.Estate, New Delhi. It has further certified that the firm deals in foodgrain, dry fruit (kaju) and kiryana goods and other goods. If the certificate produced by the petitioner is in any way found to be suspicious, nothing prevented the officer from enquiring the same with the office who issued Exhibit P6 regarding its veracity. No such attempt was made. Further prima facie the genuineness of Exhibit P6 cannot be doubted. Further for effecting an inter state sale, Section 6 as such does not insist that it should be always to a registered dealer. However, if any claim is made based on the 'F' form so issued by the consignee, it is open to the assessing authority to consider the same.
