State mineral-rights tax beyond legislative competence where Parliament has limited royalty and mineral development control.

Entry 50 of List II permits State taxation on mineral rights only subject to Parliamentary limitations on mineral development; applying India Cement, the Court treated royalty under section 9 of the Mines and Minerals (Regulation and Development) Act, 1957 as a statutory limit on the State's taxing power. It therefore held section 3 of the Andhra Pradesh (Mineral Rights) Tax Act, 1975 ultra vires to the extent it imposed a burden beyond what Parliament had permitted, so the levy could not continue for the future. However, because past collections had been made under prior decisions and legal uncertainty, the Court declined to order refund of tax already collected.

Issues: (i) Whether section 3 of the Andhra Pradesh (Mineral Rights) Tax Act, 1975 was beyond the legislative competence of the State Legislature in view of Entry 50 of List II read with Entry 54 of List I and the Mines and Minerals (Regulation and Development) Act, 1957; (ii) whether the tax already collected under the State Act was liable to be refunded.

Issue (i): Whether section 3 of the Andhra Pradesh (Mineral Rights) Tax Act, 1975 was beyond the legislative competence of the State Legislature in view of Entry 50 of List II read with Entry 54 of List I and the Mines and Minerals (Regulation and Development) Act, 1957.

Analysis: Entry 50 of List II permits taxation on mineral rights only subject to limitations imposed by Parliament by law relating to mineral development. The Central enactment declared Union control over the field of regulation and development of mines and minerals and, in section 9, provided for royalty and its enhancement only in the manner and to the extent there prescribed. On the reasoning adopted in India Cement, royalty was treated as a tax and section 9 of the Central Act was viewed as a limitation on the State's power to levy a tax on mineral rights. The Court held that the Central legislation occupied the relevant field and that the State could not by a tax on mineral rights, in substance, enlarge the burden beyond what Parliament had permitted.

Conclusion: Section 3 of the State Act was ultra vires the legislative power of the State Legislature and the levy could not be sustained in future.

Issue (ii): Whether the tax already collected under the State Act was liable to be refunded.

Analysis: The Court considered the position in light of the prior legal uncertainty created by earlier decisions upholding the levy and the fact that collections had been made while those decisions held the field. On that basis, the Court declined to direct restitution of amounts already collected.

Conclusion: The tax already collected was not refundable.

Final Conclusion: The writ petitions succeeded to the extent that the levy under the State Act was struck down for the future, while past collections were left undisturbed.

Ratio Decidendi: Where Parliament has occupied the field of mineral development and has imposed a statutory limitation on royalty or mineral-rights taxation, a State levy that in substance adds to that burden is beyond the State Legislature's competence.
