Municipal octroi and promissory estoppel: existing tax rules continued after inclusion, and interim injunction was refused.

Upon inclusion of factory land within municipal limits, the existing octroi notification continued to apply to the enlarged municipal area under the applicable scheme, so the challenge to recovery of octroi failed at the prima facie stage. An agreement purporting to restrain future municipal inclusion and taxation was treated as contrary to public policy because the State cannot contract away future legislative or executive powers; promissory estoppel also could not defeat lawful municipal action. The court further held that the applicant's three-year delay, together with the balance of convenience favouring lawful revenue collection, justified refusal of temporary injunction.

Issues: (i) Whether the appellant had made out a prima facie case for interim injunction against recovery of octroi after inclusion of the factory area within municipal limits; (ii) Whether the agreement restraining future municipal inclusion and taxation was enforceable or could be enforced through promissory estoppel; (iii) Whether the balance of convenience and delay justified refusal of temporary injunction.

Issue (i): Whether the appellant had made out a prima facie case for interim injunction against recovery of octroi after inclusion of the factory area within municipal limits?

Analysis: The amended scheme under Section 4(8)(d) of the Rajasthan Municipalities Act, 1959 provided that, upon inclusion of an area in a municipality, the existing rules, notifications, orders and bye-laws applicable to that municipality would continue to apply to the newly included area until replaced. The octroi notification already in force for Lakheri Municipality therefore applied to the included factory area without the need for a fresh notification. The foundation of the appellant's challenge to recovery of octroi was therefore not established.

Conclusion: The appellant failed to show a prima facie case on the octroi issue.

Issue (ii): Whether the agreement restraining future municipal inclusion and taxation was enforceable or could be enforced through promissory estoppel?

Analysis: The agreement was held to be contrary to public policy because the State could not contract away its future legislative or executive powers, particularly in relation to local self-government and municipal administration. The plea of promissory estoppel also failed because no factual foundation had been laid in the pleadings, and in any event the doctrine cannot be used to prevent the State from performing duties imposed by law or from exercising legislative powers. The Court treated the agreement as not binding to the extent it fettered future governmental action.

Conclusion: The agreement was not enforceable against the State, and promissory estoppel could not bar the municipal extension.

Issue (iii): Whether the balance of convenience and delay justified refusal of temporary injunction?

Analysis: The principles governing temporary injunction required a prima facie case, irreparable injury, and balance of convenience in favour of the applicant. The Court found that the appellant had delayed challenging the notification for more than three years, and such stale claim did not merit equitable relief. The potential inconvenience to the municipality from restraint of lawful revenue collection outweighed any asserted hardship to the appellant, especially because the demand did not disclose irreparable loss warranting interim protection.

Conclusion: The balance of convenience was against grant of injunction and the delay independently justified refusal of equitable relief.

Final Conclusion: The challenge to the municipal inclusion and consequential octroi collection failed, and the refusal of interim injunction was upheld, leaving the suit unsupported at the interlocutory stage.
