6.

Likewise, in each showcause notice, different details were shown. Thus, in view of the variation from notice to notice, there is any amount of doubt about actual purchases outside the state. In fact, the Writ Petitioner sought for furnishing copies of invoices and other relevant information from the respondent but obviously for different reasons, the respondent did not supply the information and, on the other hand, issued a notice to obtain copies. This procedure adopted by the respondent in levying tax without furnishing copies of invoices and other material on which assessment was made is against the principles of natural justice. In Sri Uma Maheshwara Rice & Flour Mill, Vetlapalem Vs. Commercial Tax Officer, Peddapura m[1] , in similar circumstances, the order was declared as arbitrary on the ground that the impugned assessment order was passed without furnishing information sought for.
