Dynamic octroi notification interpretation upheld later rates and expanded articles under an existing levy.

The Supreme Court construed the 1881 octroi notification as a continuing authorisation, so the phrase "for the time being" covered later-prescribed rates and articles later added to the dutiable schedule. The 1918 notifications did not wholly supersede the 1881 notification, though the octroi-specific notifications of 1918 were treated as having fallen into desuetude before the 1963 rules were applied. Collection under the 1963 octroi rules was therefore not invalid for want of a fresh agreement, excessive delegation, or failure to follow the initial tax-imposition procedure under the Cantonments Act, 1924, because the revision was treated as an enhancement of an existing levy.

Issues: (i) Whether the 1881 notification authorised collection of octroi at rates later prescribed and on articles later added to the schedule; (ii) whether the 1918 notifications superseded or rendered obsolete the 1881 notification in relation to octroi; (iii) whether collection under the 1963 octroi rules was invalid for want of a fresh agreement, for excessive delegation, or for non-compliance with the procedure for imposition of tax under the Cantonments Act, 1924.

Issue (i): Whether the 1881 notification authorised collection of octroi at rates later prescribed and on articles later added to the schedule.

Analysis: The expression "for the time being" in the 1881 notification was construed in the setting of the surrounding administrative history and long-standing practice. The Court held that the notification was not confined to the rates and articles prevailing on the date of its issue, and that the language was intended to permit levy at subsequently prevailing rates and on articles later becoming dutiable.

Conclusion: The 1881 notification authorised collection of octroi at the rates specified in the 1963 rules and on the expanded list of articles.

Issue (ii): Whether the 1918 notifications superseded or rendered obsolete the 1881 notification in relation to octroi.

Analysis: The Court held that the supersession clause in the 1918 notifications was confined to the taxes actually dealt with in the relevant notification and did not expressly or by necessary implication wipe out the earlier octroi notification. However, the later notifications dealing specifically with octroi and its assessment, collection, and recovery were treated as having displaced the 1881 octroi arrangement. The Court further accepted that long non-use coupled with contrary practice justified treating those later notifications as having fallen into desuetude by 1963.

Conclusion: The 1918 notifications did not supersede the 1881 notification as such, but the octroi notifications of 1918 were treated as having ceased to operate by desuetude before the 1963 rules were applied.

Issue (iii): Whether collection under the 1963 octroi rules was invalid for want of a fresh agreement, for excessive delegation, or for non-compliance with the procedure for imposition of tax under the Cantonments Act, 1924.

Analysis: Once the 1881 notification was held to continue to authorise octroi collection, the absence of a fresh agreement after the 1963 revision did not create illegality. The Court further held that the notification did not amount to impermissible delegation, because the legislative policy was sufficiently indicated and the cantonment taxation scheme contemplated such adaptation. As to the procedure under sections 60 to 63 of the Cantonments Act, 1924, the Court distinguished initial imposition of tax from mere enhancement of an existing levy and held that the objection procedure was not attracted to the revised 1963 rates.

Conclusion: The collection under the 1963 octroi rules was not invalid on any of the asserted legal grounds.

Final Conclusion: The municipal collection of octroi under the 1963 rules was upheld, and the writ petitions challenging the levy failed.

Ratio Decidendi: A statutory notification using language of continuing application may authorise later rates and later dutiable articles where the context shows an intended dynamic reference, and a later tax revision does not require the full procedure for first imposition where it is only an enhancement of an existing levy under the governing scheme.
