G and his son V belonged to a Hindu undivided family, and as represcntatives of the family were partnero in the assesee-firm holding therein shares of 7t as. and 2t as. respectively. The family thus held through them, an interest of 10 as. in the assessee-firm. On August 24, 1950, there was a partition in the family, and according to the partition-deed the IO as. interest of the family in the assessee-firm was divided in such a way between seven members that the shares allotted to G and V came to 2 as. and I anna 4 pies respectively. On November 30, 1950, a new . partnership-deed was drawn up by the partners of the assessee-firm and the shares allotted to G and V therein were again 7t as. and 2t as. respectively. The claim of the ru;sessee-firm for Registration under s. 26-A of the Indian Income-tax Act, 1922, on the basis of the new deed, for the yean 1952-53, 1953-54 and 1954-55 wru; accepted by the Income-tax.authorities. G and V were duly assessed on their respective shares as shown in the partnership deed. But they contended that in respect of the first two years they were liable to pay tax only in respect of their respective shares as shown in the partition-deed of their erstwhile undivided family. Their contention was accepted by the Income-tax Appellate Tribunal. Whereupon, the Commissioner of Income-tax acting under s. 33B of the aforesaid Act cancelled the registration of the partnership for the three years on the ground that the partnership-deed did not show the correct shares of the partners in the partnership. The Tribunal, in appeal, upheld the Commissioner's action. At the as&"...ssee's instance, a reference was then made to the High Court of Judicature at Allahabad, the questions rererred bein& whether the Commissioner's action under s. 33B was lawful, and if so, wh• ther the firm was registerable under s. 26A for the assessment yean in question. The High Court decided both the questions in favour of the • assessee and against the · Revenue. The Commissioner of Income...tax appealed to this court.
