Rateable value under municipal tax law excludes plant and machinery in a building absent valid, standard-guided statutory inclusion.

Rateable value under the Delhi Municipal Corporation Act is confined to land or building value and does not ordinarily include the cost of plant and machinery, including lifts and air-conditioners, installed in or upon a building unless a valid public notice under Section 116(3) brings specified classes within the exception. The commentary also addresses delegated legislation, noting that the provision was treated as lacking discernible standards for selecting includible classes and therefore as an instance of unguided and uncanalised discretion amounting to excessive delegation.

Issues: (i) Whether the cost of plant and machinery, including lifts and air-conditioners, installed in or upon a building can be included in the rateable value of the building under the Delhi Municipal Corporation Act, 1957; (ii) Whether Section 116(3) of the Delhi Municipal Corporation Act, 1957 confers arbitrary and uncanalised discretion on the Commissioner and is therefore invalid for excessive delegation.

Issue (i): Whether the cost of plant and machinery, including lifts and air-conditioners, installed in or upon a building can be included in the rateable value of the building under the Delhi Municipal Corporation Act, 1957.

Analysis: The statutory scheme treated rateable value as a value referable to land or building, and Section 116(3) laid down the general rule that plant and machinery in or upon land or building were not to be taken into account, save where a valid public notice brought specified classes of plant or machinery within the exception. The functional distinction between "land", "building" and "premises" could not be collapsed so as to enlarge the tax base beyond the text of Section 116(3). The Court applied the settled approach that taxing provisions must be construed strictly, and that machinery or equipment cannot be included merely because it is embedded in, annexed to, or beneficial to the use of the building.

Conclusion: The cost of plant and machinery, including lifts and air-conditioners, could not be included in the rateable value unless covered by a valid notification under Section 116(3).

Issue (ii): Whether Section 116(3) of the Delhi Municipal Corporation Act, 1957 confers arbitrary and uncanalised discretion on the Commissioner and is therefore invalid for excessive delegation.

Analysis: The provision permitted inclusion of specified classes of plant and machinery by public notice with approval of the Standing Committee, but it did not lay down discernible legislative standards governing the selection of such classes. The appeal to the definitions of "land" and "building" did not supply an adequate guideline, because the power under Section 116(3) operated precisely where the item did not already fall within those definitions. The existence of approval by the Standing Committee and a general appeal against assessment did not cure the absence of standards for the initial inclusion decision. Applying the principles governing delegated legislation, the Court held that essential legislative policy had not been sufficiently controlled by the statute.

Conclusion: Section 116(3) was invalid for conferring unguided and uncanalised power amounting to excessive delegation.

Final Conclusion: The assessments based on inclusion of plant and machinery, lifts and air-conditioners could not stand, the contrary High Court view was rejected, and the matter was sent back for fresh assessment in accordance with law.

Ratio Decidendi: In municipal taxation, plant and machinery installed in or upon a building cannot be included in rateable value unless the statute validly authorises such inclusion through a rule-bound and standard-guided delegation; a provision that leaves the selection of includible classes to unguided executive discretion is invalid for excessive delegation.
