The purpose of my amendment is to exempt all properties and income of a State from Union taxation, even when the State is carrying on a business or trade within its own limits. The Union will have no power to tax properties or income of a State in one case where the State carried on a business or trade outside its limits. This principle of immunity from inter-governmental taxation was accepted by this House when it accepted article 264 where it is provided that the properties of the Union shall be exempt from taxation by a State. I only want that this principle should be extended and applied in the case of the States as well. In the United States Constitution there is no provision exempting the Union properties or State properties from reciprocal taxation. But, in interpreting the Constitution the Supreme Court has very clearly laid down this principle of immunity from reciprocal taxation. power to tax was held to involve power to destroy. Until recently, even the income of an officer of a State was exempted from the taxation of the Union. Later on, however, in applying this principle the Supreme Court began to draw a sharp line of distinction between the governmental and traditional functions of a government on one side and the business or trade carried on by a State merely for the purpose of profit on the other. Immunity was denied in cases where the State carried on a business or trade as distinct from a governmental function. But to define ‘governmental function’ is not easy. What might have been deemed in earlier days as a dangerous expansion of State activities may today be deemed to an indispensable function of the Government. The State Government does not exist for its own sake. It enters the field of private enterprise, not with profit motive alone. It is no doubt the duty of a State to nationalise public utility services and also the key industries. The modern concept of a State is such that the conduct of a business or trade within its own limit very often becomes a function of a State. There is an express provision in the Constitution of the Commonwealth of Australia granting immunity from reciprocal taxation. Section 114 of the Constitution reads : “A state shall not without the consent of the Parliament of the Commonwealth raise or maintain any naval or military force or impose any tax on property of any kind belonging to the Commonwealth, nor shall the Commonwealth impose any tax on property of any kind belonging to a State.”
