Capital value property tax rules must stay within statutory limits and cannot tax future development potential or operate retrospectively.

Municipal property tax may be shifted from rateable value to capital value where the statutory scheme authorises such taxation and valuation machinery, so the change in computation method does not by itself offend constitutional competence. The delegated rules, however, must stay within the parent Act: valuation may be based only on present, ascertainable attributes and the ready reckoner framework, not on future development potential such as higher FSI or TDR, so rules adopting that approach were ultra vires. The capital value rules also could not be applied retrospectively from 1 April 2010 because the enabling provisions did not authorise retrospective fiscal liability.

Issues: (i) Whether the State Legislature and the municipal authorities had the competence and authority under the Constitution and the municipal law to shift the levy of property tax from rateable value to capital value and to provide the related machinery for fixation and collection of tax; (ii) whether the rule-making power under the municipal statute permitted the Commissioner to adopt future development potential, including higher FSI and TDR, for fixing capital value and whether Rules 20, 21 and 22 were ultra vires; (iii) whether the Capital Value Rules of 2010 could operate retrospectively from 1 April 2010.

Issue (i): Whether the State Legislature and the municipal authorities had the competence and authority under the Constitution and the municipal law to shift the levy of property tax from rateable value to capital value and to provide the related machinery for fixation and collection of tax?

Analysis: The constitutional scheme under Article 243X permits the Legislature to authorize a municipality to levy and collect taxes in accordance with law, while Article 243Y does not require that every reform measure must originate only from the Finance Commission. The municipal provisions relating to taxation, budget, fixation of rates, adoption of capital value and determination of capital value formed a complete statutory framework. The shift from rateable value to capital value altered only the method of computation and not the legislative competence to impose property tax.

Conclusion: The challenge to legislative competence and the related constitutional objections failed.

Issue (ii): Whether the rule-making power under the municipal statute permitted the Commissioner to adopt future development potential, including higher FSI and TDR, for fixing capital value and whether Rules 20, 21 and 22 were ultra vires?

Analysis: The statute required capital value to be determined by reference to the present characteristics of the land or building and the ready reckoner base value, together with the stated factors in the Act. Those factors were held to be confined to present, ascertainable attributes and not future prospects or anticipated exploitation. Rule 20, by adding value on account of capability to use higher FSI or TDR, introduced an element of future potential beyond the statutory field. Rule 21, to the extent it embodied the same approach, and Rule 22, which gave primacy to the rules over the ready reckoner guidelines, also exceeded the rule-making power.

Conclusion: Rules 20, 21 and 22 were ultra vires and were rightly struck down.

Issue (iii): Whether the Capital Value Rules of 2010 could operate retrospectively from 1 April 2010?

Analysis: The enabling provisions did not confer power to make the delegated legislation operate retrospectively so as to fasten liability for a period before the rules came into force. The preparatory steps taken earlier did not create retrospective taxing authority. The Rules became effective only on their commencement and could not govern earlier periods by retrospectivity.

Conclusion: The Capital Value Rules of 2010 could not be applied retrospectively from 1 April 2010.

Final Conclusion: The statutory transition to capital-value-based property taxation was upheld in principle, but the rules could not travel beyond the Act by introducing future development potential or retrospective levy, and the relief granted by the High Court on those counts was sustained.

Ratio Decidendi: In a capital-value tax regime, delegated legislation must remain confined to the present statutory factors for valuation and cannot incorporate future developmental potential or create retrospective fiscal liability unless the parent statute clearly authorizes it.
