Purchase and sale of shares outside the floor of Stock Exchange is not an unlawful activity. Off-market transactions are not illegal. It is always possible for the parties to enter into transactions even without the help of brokers. Therefore, it is not possible to hold that the transactions reported by the assessee were quite sham on the legal proposition arrived at by the CIT(A) that off-market transactions are not permissible. The assessee has stated that the transactions were made with the help of professional mediators who are experts in off-market transactions. When the transactions were off-market transactions, there is no relevance in seeking details of share transactions from Stock Exchanges. Such attempts would be futile. Stock Exchanges cannot give details of transactions entered into between the parties outside their floor. Therefore, the reliance placed by the assessing authority on the communications received from the Stock Exchanges that the particulars of share transactions entered into by the assessee were not available in their records, is out of place. There is no evidential value for such reliance placed by the assessing authority. The assessee had made it very clear that the transactions were not concluded on the floor of the Stock Exchange. The matter being so, there is no probative value for the negative replies solicited by the assessing authority from the respective Stock Exchanges. We are of the considered view that the materials collected by the assessing authority from the Stock Exchanges are not valid to dispel or disbelieve the contentions of the assessee
