B. R. Ltd vs V. P. Gupta, C.I.T., Bombay on 3 May, 1978
"The learned counsel for the assessee strongly relies on the decision of the Supreme Court in B. R. Ltd. v. V. P. Gupta, CIT (1978) 113 ITR 647 (SC), and contends that the decisive test to be applied in this case is the unity of control and not the nature of the lines of business, and that as this case satisfies the test of unity of control, it should be held that the assessee is carrying on the same business though the lines of business carried on by it may be different. But we are of the view that the said decision of the Supreme Court cannot be taken as laying down that unity of control is the only and sole test to be adopted as contended by the assessee. On the facts of that case, the Supreme Court had to consider the efficacy of the two tests, one, unity of control and, the other, the different lines of business, and as between the two tests, the Supreme Court expressed the view that the test of unity of control should prevail over the other test relating to nature and the lines of business. The said decision of the Supreme Court cannot be taken to have overruled its earlier decisions which laid down the multifarious tests to determine whether the various businesses run by an assessee is one and the same or different and independent business. If unity of control is taken to be the sole and exclusive test, then in all cases where an assessee finances, controls and carries on more than one business, then all businesses will have to naturally be treated as one business, because there is unity of control.
