Expansion of existing plant denied electricity duty exemption where the unit was not a separate industrial undertaking.

A cement plant unit was held not to qualify as a new industrial undertaking for electricity duty exemption because it was an expansion of an existing business. The governing exemption provision expressly excluded undertakings formed by expansion, and the unit depended on the existing plant's crushers, cranes, raw mills, packing machinery and other old assets to complete production. A new undertaking must be a physically separate, identifiable and viable unit capable of independent operation; here, the old and alleged new units retained the same physical identity. The exemption available under the Income-tax Act was distinguishable because the present statute specifically barred expansion cases.

Issues: Whether the respondent's cement plant unit constituted a new industrial undertaking entitled to exemption from electricity duty under the Act, or was merely an expansion of an existing undertaking and therefore outside the exemption.

Analysis: The statutory scheme exempted a new industrial undertaking, but the definition expressly excluded an undertaking formed by expansion of an existing business or undertaking in the State. The unit in question was not independent of the existing plant: it used crushers, cranes, raw mills, packing machinery and other old assets to complete the manufacturing process. A new undertaking must emerge as a physically separate and identifiable unit capable of operating as a viable unit on its own. On the facts, the physical identity with the old unit was preserved and the alleged new unit depended on the existing unit's assets. The exemption granted in the context of the Income-tax Act was distinguishable because the present statute specifically excluded expansion cases.

Conclusion: The respondent was not entitled to exemption from electricity duty, as the unit was an expansion of the existing undertaking and not a new industrial undertaking under the Act.

Ratio Decidendi: Where the governing exemption provision excludes expansion of an existing undertaking, a unit that depends on the existing plant and machinery and does not operate as a separate, physically distinct, and viable industrial unit cannot be treated as a new industrial undertaking for exemption purposes.
