Industrial township notification does not create a Municipality; Section 10(20) exemption applies only to listed local authorities.

A notification declaring an industrial area as an industrial township under the proviso to Article 243Q does not by itself create a Municipality under Article 243P(e) or confer Part IXA municipal status on the Authority. After the Finance Act, 2002, "local authority" in the Explanation to Section 10(20) is an exhaustive definition limited to the entities expressly listed, so broader meanings under the General Clauses Act or earlier functional approaches do not apply. As the Authority was not within that list, it was not entitled to income-tax exemption and remained outside the statutory exemption regime.

Issues: (i) Whether the notification specifying the industrial area as an industrial township under the proviso to Article 243Q of the Constitution of India made the Authority a Municipality within Article 243P(e); (ii) Whether the Authority fell within the exhaustive definition of "local authority" in the Explanation to Section 10(20) of the Income-tax Act, 1961 after the Finance Act, 2002.

Issue (i): Whether the notification specifying the industrial area as an industrial township under the proviso to Article 243Q of the Constitution of India made the Authority a Municipality within Article 243P(e).

Analysis: The proviso to Article 243Q operates as an exception to the constitutional mandate for constitution of Nagar Panchayats, Municipal Councils and Municipal Corporations. A notification under that proviso only relieves the requirement of constituting a Municipality in the specified area. It does not itself constitute the industrial establishment or industrial township as a Municipality, and the constitutional attributes of a Municipality under Part IXA are not thereby conferred on the Authority.

Conclusion: The Authority was not a Municipality within Article 243P(e) merely because of the industrial-township notification.

Issue (ii): Whether the Authority fell within the exhaustive definition of "local authority" in the Explanation to Section 10(20) of the Income-tax Act, 1961 after the Finance Act, 2002.

Analysis: After the Finance Act, 2002, the expression "local authority" in Section 10(20) is an exhaustive definition confined to the entities specifically enumerated in the Explanation. The wider meaning under the General Clauses Act and the earlier functional approach could not be imported. Since the Authority was neither a Panchayat, nor a Municipality, nor a Municipal Committee or District Board, nor a Cantonment Board, it could not claim exemption under Section 10(20). The omission of Section 10(20A) also withdrew the earlier exemption available to development authorities.

Conclusion: The Authority was not covered by Section 10(20) and was not entitled to income-tax exemption.

Final Conclusion: The challenged notices were held sustainable, and the dismissal of the writ petition and review was affirmed, leaving the Authority outside the statutory exemption regime.

Ratio Decidendi: A proviso creating an industrial township does not constitute the area as a Municipality, and the post-amendment definition of "local authority" in Section 10(20) of the Income-tax Act, 1961 must be applied strictly as an exhaustive list, without importing broader meanings from other statutes.
