Retrospective validation of electricity tax and controlled municipal taxing power upheld against challenge of excessive delegation.

The Supreme Court upheld retrospective validation of electricity tax liability under the Delhi Municipal Corporation (Validation of Electricity Tax) Act, 1966, construing it as deeming the 1959 resolution valid and treating the specified rates as operative for the entire period from 1 July 1959 to 31 March 1966. It also rejected the challenge to section 150 of the Delhi Municipal Corporation Act, 1957, finding that the municipal power to levy optional taxes, including electricity tax, was sufficiently controlled by the Act's purposes, budgetary framework, elected character of the corporation, and Government supervision, so the delegation was not excessive. The levy was sustained.

Issues: (i) Whether the Delhi Municipal Corporation (Validation of Electricity Tax) Act, 1966 validly imposed and validated liability to pay electricity tax for the period 1 July 1959 to 31 March 1966; (ii) whether section 150 of the Delhi Municipal Corporation Act, 1957 suffered from excessive delegation of legislative power in authorising the Municipal Corporation to levy optional taxes, including electricity tax.

Issue (i): Whether the Delhi Municipal Corporation (Validation of Electricity Tax) Act, 1966 validly imposed and validated liability to pay electricity tax for the period 1 July 1959 to 31 March 1966.

Analysis: The validating enactment was construed as doing more than merely validating the rate-fixing resolution. Its first part deemed the resolution of 24 June 1959 to have been passed in accordance with law and treated the rates specified therein as the actual rates of tax for the entire stated period. The second part further deemed all taxes levied or collected pursuant to that resolution to have been validly levied or collected. Read together, the provisions were held to impose and validate liability for the whole period, not merely for a part of it.

Conclusion: The validation statute effectively imposed and validated the electricity tax liability for the entire period in question, in favour of the Revenue.

Issue (ii): Whether section 150 of the Delhi Municipal Corporation Act, 1957 suffered from excessive delegation of legislative power in authorising the Municipal Corporation to levy optional taxes, including electricity tax.

Analysis: The Act was held to contain sufficient guidance and control for the municipal levy of optional taxes. The Corporation was an elected local body charged with defined municipal functions requiring finance; its taxing power operated within the purposes of the Act, within the budgetary framework, and under Government sanction. The nature of local taxation, the elective character of the body, the statutory limits inherent in municipal functions, and the supervisory role of Government were treated as adequate controls preventing the delegation from becoming unguided or arbitrary.

Conclusion: Section 150 did not amount to excessive delegation and was upheld as constitutionally valid, in favour of the Revenue.

Final Conclusion: The tax levy was sustained and the writ petitions failed, as both the validating statute and the delegation scheme under the municipal enactment were upheld by the majority.

Ratio Decidendi: A legislature may validly entrust a local self-governing municipal body with power to levy specified local taxes where the statute furnishes sufficient control, guidance, and supervisory safeguards, and a validating enactment may retrospectively cure defects in levy and collection by deeming the tax to have been validly imposed for the relevant period.
