72. It appears that under the new Constitution, residuary power will be vested in the Centre, so far as the provinces are concerned, while the corresponding residuary powers in respect of the States will be vested in the States themselves, he question has therefore been raised whether, as a consequence, as many specific taxes as possible should not be entered in the Provincial List of subjects. We cannot think of any important new tax that can be levied by the provinces, which will not fall under one or the other of the existing categories included in the Provincial List. We think that the chance of any practical difficulty arising out of the proposed constitutional position is remote, and, in any case, it seems to us that if a tax is levied by the Centre under its residuary powers, there will be nothing to prevent the proceeds of the whole or a part of this tax being distributed for the benefit of the provinces only. As a matter of abundant caution, however, it may be laid down in the Constitution that if any tax is levied by the Centre in future under its residuary powers, and to the extent that the States do not agree to accede to the Centre in respect of the corresponding subject, the whole or a part of the proceeds of the tax shall be distributed between the provinces and the acceding States only. This disposes of Item IX of our terms of reference.
