During the course of survey operation on the assessee, a manufacturer of PVC, excess stock of Rs.13,92,000 was found. On this basis, an addition was made in the assessment order. Before the Commissioner of Incometax (Appeals), the assessee sought to explain this difference by pointing out that sales of 32,809 kgs. of finished products made by one of the sister concerns, namely, Ashish Agro Plast P. Ltd. was wrongly shown as to be that of the assessee. On remand it was found that sales of finished product of 32,809 kgs. as shown is sales register of the sister concern tallied with impounded stock register and that the sister concern had received sales proceeds of the same through the bank accounts prior to the date of survey. It was however further found that sale of 33,682 kgs. of finished goods was nothing but unaccounted sales out of which 32,809 kgs. was made to the aforesaid sister concern. Taking this into consideration, the Commissioner of Income-tax (Appeals) upheld the addition. This order was upheld by the Tribunal and the High Court. The Supreme Court issued a notice on a Special Leave Petition being filed by the assessee limiting to the question as to whether in respect of sales of 32,809 kgs. which were shown in the stock register of Ashish Agro Plast P. Ltd., there had been double taxation. The Supreme Court remanded the case back to the Assessing Officer authority for enabling the assessee to demonstrate as to whether the sister concern had already paid tax on the aforesaid income from the aforesaid sales and directing that, if that was shown, to the extent of tax that was paid, benefit should be accorded to the assessee.
