There is absolutely no discussion of the law and why the coordinate Bench decision rendered at Delhi is either distinguishable on facts or inapplicable. There is no discussion, much less any finding and conclusion that the order of the First Appellate Authority is perverse or is contrary to law. There are no infirmities, much less serious errors of fact and law noted by the Tribunal in the order of the Commissioner, which the Tribunal is obliged to and which order is therefore interfered by the Tribunal. Why the Tribunal feels it is its duty and obligation to interfere with the order of the First Appellate Authority, therefore, should be indicated with clarity. We have also not seen a reference to any communication or to any document which would indicate that the six queries raised by the Tribunal on the assessee have not been answered, much less satisfactorily. The Tribunal should have, independent of the statements, referred to such of the materials on record which would disclose that the assessee has entered into such arrangements so as to avoid the obligation to deduct the tax at source. If the arrangements are sham, bogus or dubious, then such a finding should have been rendered. Therefore, we are most unhappy with the manner in which the Tribunal has decided these Appeals. We have no alternative but to set aside such order and when the last fact finding authority misdirects itself totally in law. It fails to perform its duty. It has also not rendered a complete decision. Once the Tribunal was obliged in law to examine the matter and reappraise and reappreciate all the factual materials, then it should have performed that duty satisfactorily and in terms of the powers conferred by law
