order to deprive the State of legitimate revenue by way of stamp duty. Section 47-A of the Act empowers the Collector to act under this provision in case of deliberate arrangement to undervalue the property to evade payment of stamp duty. In order to bring the case within the ambit of Section 47-A of the Act, it is mandatory that the consideration stated in the instrument of conveyance, exchange, gift etc., should be less than the actual value of the transaction. The object underlying the aforesaid provision is to neutralize the effect of under-valuation of immovable property which is sought to be conveyed through a registered instrument. Ordinarily, in a transaction of immovable property by transfer or exchange or partition or gift etc., where the transferor is State or public authority, the provision of Section 47-A of the Act would not be attracted as in such transaction, undervaluation may not be involved. However, where the transaction itself is shown to be actuated by fraud or other factor, the provisions of Section 47-A of the Act would be attracted.”
