M/S. Tungabhadra Industries Ltd vs The Commercial Tax Officer, Kurnool on 18 October, 1960
11. We are supported in our above conclusion by the decision of the Supreme Court in Tungabhadra Industries Ltd. v. Commercial Tax Officer [1960] 11 STC 827 where hydrogenated groundnut oil (commonly called vanaspati) was held to be groundnut oil. In that case, the Supreme Court held that processing of groundnut oil in order to render it more acceptable to the customer by improving its quality would not render it a commodity other than groundnut oil.
