This takes us to the decision in Balasundaram & Co's case c (supra). This case was decided by the same bench which decided Swami & Co's case. Therein the assessee was assessed to sales tax under the 1939 Act. During the pendency of its appeal to the Commercial Tax Officer, the 1959 Act came into force. Its appeal was transferred to the Appellate Assistant Commissioner who enhanced the assessment. But on a further appeal, the D Tribunal came to the conclusion that the Appellate Assistant Commissioner had no jurisdiction to enhance the assessment. As against that order, the Deputy Commissioner of Commercial Taxes went up in revision to the High Court. The High Court held that the assessee had a vested right at the time when the 19 59 Act came into force to prevent the Commercial Tax E Oilicer from enhancing the assessment in the course of the appeal preferred by him. However, there was always the peril of the , Commercial Tax Officer, who was also the revising authority, ·revising the assessment to his prejudice in exercise of his revisional power, but that peril effectively disappeared when under the 1959 Act, the revisional power was conferred upon the Deputy ComF missioner of Commercial Taxes and not upon the Appellate Assistant Commissioner. Therefore the interference by the Appellate Assistant Commissioner with the assessment order passed by the Deputy Commercial Tax Officer to the prejudice of the assessee in the purported exercise of his appellate power, was clearly violative of the assessee's vested rights. In our opinion this G decision proceeded on a wrong basis. The question before the High Court was whether there was a vested right in the assessee not to have his assessment enhanced, under the 1939 Act and whether that vested right had been in any manner infringed by the 1959 Act. As seen earlier he had no such vested right under . the 1939 Act. The fact that a different procedure is prescribed under the 1959 Act for enhancing the assessment cannot be said H to be an infringement of a vested right. No one can have a vested right in a mere procedure. We are of opinion that Balasundaram's case (supra) was wrongly decided and some of the observations
