relation to which the addition is threatened, was located within the State of Bihar, that too inside the boundaries of Patna. We, specifically notice Section 127 which clothes the Principal Director General, Director General, the Principal Chief Commissioner, Chief Commissioner or Commissioner to transfer any case from one or more Assessing Officers subordinate to him, whether with or without concurrent jurisdiction to any other Assessing Officer or Assessing Officers also subordinate to him. However, the specific mandate in Section 127 is that the Assessee should be given a reasonable opportunity of being heard in the matter wherever it is possible to do so. There is no circumstance brought on record which made the extension of such an opportunity, which is also the statutory mandate, to be impossible in the facts of the present case. Obviously, the transfer was done behind the back of the petitioner. We find no reason to uphold the order of assessment, which was passed pursuant to a notice issued on the wrong premise of a transfer made by the Commissioner without following the principles of natural justice, which is specifically made a mandate in the provision enabling such transfer.
