Ostensibly, the Assessing Officer ought to have brought on record material which is relevant to the transactions of the assessee with the aforesaid four parties instead of making a general observation about the information received from the Sales Tax Department of the Government of Maharashtra. Quite clearly, the Assessing Officer as well as CIT(Appeals) have taken note of the fact that no sales could have been effected by the assessee without purchases. In the present case, assessee has explained that all its sales are by way of exports. The books of account maintained by the assessee show payment for effecting such purchases by account payee cheques and also the vouchers for sale and purchase of goods, etc. Notably, no independent enquiries have been conducted by the Assessing Officer
