· Bhargava, J. · These appeals arise out of proceedings for assessment of sales-tax under the Madras General Sales Tax Act . No. IX of 1939 (hereinafter referred to as "the Act") in respect of certain sales of cotton. The respondents were registered dealers in cotton, including kappas, groundnuts and cotton seeds with their Head Office at Bellary and Branch O;Iices at a number of places. They were also licensees under s. 8 of. the Act in respect of cotton. They made various purchases of cotton at their places of business and subsequently sold them to different parties. Amongst these were a number of persons who were not resident within the area to which the Act applied. The question arose as to who was liable to pay· the sales-tax in respect of those transactions of sale of cotton in which the cotton had been sold by the respondents to non-residents. When the case came up before the Mysore Sales .Tax Appellate Tribunal, the Tribunal determined the c.ourse of .transactions and held as follows : · "The examination of the contracts, the invoices, the railway receipts, insurance policies and other documents relating to the. disputed turnovers shows that the nonresident foreigners place orders for the required number of bales of cotton specifying the quality and the rate some times ori phone which would be confirmed subsequently. by Telegrams or letters and finally by written agreements. Thereupon, the appellants consign . the cotton bales in their own name, the consignee being the nonresident foreign buyer~ (except in respect of a total turnover of Rs. 2,93,5672-0 which would cover the items I, 3, 5, 7, 31, 32, 33 and 44 of the typed statement of the account for the year 1954-55 and a total turnover of· Rs. 3,71,880-13-0 which would cover the items 6, 10, 11, 12, 13, 14, 15, 16, 24, 25,·26, 29, 30, 31, 35, 36 and 37 of the typed statement of account for the year 1955-56) and send the railway receipts to their bankers at the other end for the collection of the amount. It is seen that · notwithstanding the fact that there are specific provisions in the contract that 90 per cent of the invoice amounts should . be paid to the bankers when the railway receipts would be delivered to the purchasers, surprisingly the said pro·vision. is rendered nug<:tory ty reson <'f the fact th::t the
