IBC Liquidation Overrides Municipal Retrospective Revaluation: Pre-liquidation Property Tax Cannot Be Recovered from IBC Auction Purchasers

1. Introduction

Mamta Binani & Anr. v. Kolkata Municipal Corporation & Ors. (Calcutta High Court, Constitutional Writ Jurisdiction (Original Side), decided on 16.02.2026 by Rai Chattopadhyay, J.) concerns whether the Kolkata Municipal Corporation (“KMC”) could (i) retrospectively revalue an office unit and (ii) recover the consequential property tax from purchasers who acquired the unit through an IBC liquidation e-auction.

The petitioners purchased an office space of about 3430 sq. ft. with two car parking spaces at premises no. 1B and 2, Hare Street, Kolkata from the Liquidator of Nicco Corporation Limited (in liquidation) via a registered deed dated 26.09.2019.

The dispute arose when KMC issued a notice under Sections 184/185 of the Kolkata Municipal Corporation Act, 1980 proposing revaluation effective for periods ranging from 2005–2006 to 2017–2018, and later proceeded with consequential assessment/billing, thereby attempting to fasten pre-purchase liabilities on the petitioners.

The central issues framed by the Court were: (a) whether KMC can retrospectively revalue and levy tax for periods prior to the petitioners’ purchase; (b) whether municipal dues survive liquidation under the Insolvency and Bankruptcy Code, 2016 (“IBC”); and (c) whether an IBC auction purchaser can be saddled with past statutory dues—especially where the auction terms stated “as is where is / whatever there is” and indicated liability for statutory dues.

2. Summary of the Judgment

The Calcutta High Court allowed the writ petition and held, in substance, that:

  • KMC’s notice dated 28.07.2022, and consequential assessment/billing, were unsustainable to the extent they sought to impose liability on the petitioners for any period prior to 26.09.2019.
  • Upon commencement of liquidation under the IBC, any claim for municipal dues pertaining to the period prior to the liquidation commencement date is enforceable only through the IBC framework, particularly Sections 52 and 53.
  • If KMC had a statutory charge/claim for earlier dues, it was required to be asserted before the Liquidator in accordance with the IBC and the relevant Regulations; in the absence of such lodgement/pursuit, KMC cannot recover those dues from auction purchasers by independently invoking the KMC Act.
  • KMC remains free to assess and recover property tax from the petitioners strictly from 26.09.2019 (date of transfer of title), and the petitioners’ deposit of Rs. 5,00,000/- is to be adjusted against lawful post-transfer liability.
  • The Court clarified that it was not extinguishing any statutory charge “as an abstract doctrine”; rather, it held that enforcement (if any) must conform to the IBC scheme and priorities.

3. Analysis

3.1 Precedents Cited (and How They Shaped the Outcome)

A. IBC supremacy, “clean slate” thinking, and binding effect against statutory authorities

  • Ghanashyam Mishra & Sons Private Limited versus Edelweiss Asset Reconstruction Company Limited [(2021) 9 SCC 653]
    The Court treated this 3-Judge Bench authority as settling that claims (including statutory dues owed to Government/local authorities) that are not brought within the insolvency process cannot later be enforced so as to undermine the IBC’s objectives. While the present case was a liquidation (not a resolution plan scenario), the judgment used Ghanashyam Mishra to reinforce the broader IBC policy that “residual” claims should not ambush stakeholders after the insolvency process.
  • Committee of Creditors of Essar Steel Vs. Satish Kumar Gupta [(2020) 8 SCC 531]
    Cited as the “foundational” articulation that a successful applicant should not face undecided claims after the insolvency process. The High Court drew from its logic to reject KMC’s attempt to generate liability through a post-sale retrospective revaluation exercise.
  • Sundaresh Bhatt, liquidator of ABG Shipyard Vs. Central Board of Indirect Taxes and Customs [(2022) 7 SCC 540]
    Relied upon for the proposition that, after liquidation commences, statutory authorities must channel claims through the liquidator and cannot run independent recovery tracks under their own laws. This directly supported the holding that KMC’s enforcement route had to be within the IBC.
  • Principal Commissioner of Income Tax Vs. Monnet Ispat and Energy Limited [(2018) 18 SCC 786]
    Used to confirm the breadth of the IBC’s non-obstante force (Section 238) over inconsistent statutory regimes. The Court treated this as an analogy: if the Income Tax Act yields to IBC, municipal taxation regimes must also yield where inconsistent.
  • Paschimanchal Vidyut Vitran Nigam Limited vs Raman Ispat Private Limited [(2023) 10 SCC 60]
    Invoked to reinforce that statutory dues (there, electricity-related) do not enjoy a free-standing priority outside IBC processes; the logic was applied to municipal property tax as “operational debt” within IBC’s structure.
  • Tata Power Western Odisha Distribution Limited & Another versus Jagannath Sponge Private Limited [2023 SCC OnLine SC 2442]
    Cited for the “clean slate” posture and for restricting post-insolvency pursuit of past dues against a new acquirer. The High Court used it to reject the attempt to fasten historical dues on an auction purchaser.
  • Ruchi Soya Industries vs Union of India [(2022) 6 SCC 343]
    Relied upon as part of the suite of Supreme Court authorities emphasizing the primacy of IBC mechanisms over governmental recovery outside IBC.

B. Liquidation sale purchasers and past municipal dues

  • AI Champdany Industries Limited versus Official Liquidator & Another [(2009) 4 SCC 486]
    Treated as pivotal on the proposition that past municipal tax dues of a company in liquidation are not recoverable from the auction purchaser. The Court used this to blunt KMC’s “as is where is” argument: even if the sale is on such terms, the purchaser is not required to investigate and shoulder uncrystallized historical municipal liabilities in a liquidation context.
  • Bhatpara Municipality vs Nicco Eastern Private Limited & Anr [2021 SCC Online NCLAT 612]
    Applied to characterize municipal claims as operational debts and to insist that municipal bodies participate via IBC channels; also relied on for the proposition (by using AI Champdany Industries Limited) that auction purchasers should not be burdened with prior-period dues.
  • Shiv Shakti Inter Global Exports Private Limited versus KTC Foods Private Limited [2022 SCC Online NCLAT 85]
    Used to support the approach that the insolvency framework should not permit lingering liabilities to attach to new purchasers post-sale.
  • Sri Vasavi Industries Limited & Another vs West Bengal State Electricity Distribution Company Limited [WPA No. 1936 of 2022, judgment dated March 23, 2022]
    Cited as a High Court authority reflecting similar logic on statutory dues in insolvency-related transfers; it supported the petitioners’ position that auction purchasers should not be made to answer for pre-transfer liabilities.
  • SPA Steels Rolling Mills Ltd. Vs. Asansol Durgapur Development Authority 2023 SCC Online Cal 668
    Relied upon for the petitioners’ contention that post-sale statutory demands cannot be raised in a manner inconsistent with the IBC regime.

C. Respondent’s “as is where is”, suppression, alternative remedy and municipal law authorities

  • Telengana State Southern Power Distribution Company Limited Vs. Srigdhaa Beverages reported in 2020 (6) SCC 404 and K.C. Ninan Vs. Kerala State Electricity Board and Others reported in (2023) SCC OnLine SC 663
    KMC relied on these to argue that “as is where is” sales transfer encumbrances and that purchasers are on notice. The High Court distinguished the logic on facts and on the IBC overlay: here, no quantified/cystallized municipal demand existed at the sale, and contractual clauses could not override Section 238 IBC; additionally, retrospective revaluation was initiated only later.
  • Commissioner of Customs (Preventive) Vs. Aafloat Textiles India Private Limited and Others [(2009) 11 SCC 18]
    Cited to argue that suppression disentitles writ relief. The Court rejected the allegation, noting the petitioners had referred to the EOI in the writ petition.
  • State of Madhya Pradesh and Others Vs. Shyama Charan Shukla (1972 4 SCC 371)
    Used by KMC to claim “arrears” can exist without quantification/assessment. The Court effectively neutralized this by focusing on the IBC requirement to submit claims within liquidation and by characterizing the impugned action as fresh retrospective revaluation rather than recovery of an existing, crystallized demand.
  • Rashmay Das Vs. the Kolkata Municipal Corporation & Others reported in 2012 Vol 2 CHN Cal 765
    Relied upon by KMC to contend that arrears must be paid before mutation (Section 183(5) KMC Act). The Court held it did not assist KMC because that decision did not consider the IBC’s consequences and overriding effect.
  • Calcutta Municipal Corporation Vs. Abdul Halim Gaznavi Molla & Ors. reported in 1998 SCC OnLine Cal 117 and Sahujain Charitable Society and Another Vs. The Kolkata Municipal Corporation and Others [2018 SCC OnLine Cal 4793]
    These were raised in the limitation debate (whether retrospective valuation is time-barred). The Court ultimately found it unnecessary to decide these “other points” after holding KMC’s pre-transfer enforcement against the purchasers legally unsustainable due to the IBC framework.
  • Indo Asahi Glass Company Limited and Another Vs. Income Tax Officers and Others reported in (2002) 10 SCC 444
    Cited to argue prematurity/alternate remedy. The Court nevertheless entertained the writ given the jurisdictional nature of the dispute and the incompatibility of KMC’s route with the IBC process.

3.2 Legal Reasoning

  1. IBC as a complete code with overriding force (Section 238): The Court reaffirmed that the IBC is a consolidated, time-bound insolvency/liquidation framework and that, once liquidation is ordered, claims must be handled within that statutory ecosystem. Any inconsistent municipal recovery mechanism yields to Section 238.
  2. Municipal property tax as “operational debt” (Section 5(21) IBC): The Court treated municipal property tax as falling squarely within operational debt, meaning KMC must submit and pursue its claim before the liquidator and receive distribution as per the IBC’s priorities.
  3. Waterfall priority (Section 53 IBC) governs distribution and disables “self-help” municipal recovery: The Court emphasized that municipal dues cannot leapfrog the waterfall by using municipal statute powers against purchasers post-sale.
  4. Liquidation “clean slate” is not Section 31-based; it is process-based: The judgment explicitly noted that Section 31 (binding effect of an approved resolution plan) does not apply in liquidation. Instead, the “clean slate” result (for enforcement against purchasers) follows from the combined operation of Sections 33, 35, 52, 53 and the override in Section 238, i.e., the statutory authority must join the liquidation process; if it does not, it cannot later enforce outside it against the auction purchaser.
  5. Contract terms (“as is where is / whatever there is”) cannot revive or preserve enforcement outside IBC: Even if the EOI stated that purchasers take assets subject to statutory liabilities, contractual clauses cannot defeat the IBC’s mandatory claim-channeling. Moreover, the Court stressed that no quantified arrear demand existed at the time of sale; KMC’s later retrospective revaluation could not be reframed as a pre-existing encumbrance transferred with the asset.
  6. No liability for periods when purchasers were “strangers” to the property: The Court held the petitioners cannot be made liable for tax for periods prior to their ownership (and, at most, liability could arise from the date of title transfer—held as 26.09.2019—or possibly from earlier possession as argued, but still not for the deep retrospective period claimed).
  7. Statutory charge not “extinguished in the abstract”; only enforcement is controlled: The Court’s clarification in para 50 is significant: it avoided a broad declaration that municipal “charges” vanish automatically. Instead, it held that whatever the nature of such charge, it must be asserted and enforced within the IBC’s scheme (and its priority architecture), not against auction purchasers via independent municipal machinery.

3.3 Impact

  • Municipal bodies must participate in IBC liquidations: The judgment pressures local authorities to institutionalize IBC claim-filing workflows; failure to lodge claims risks practical loss of recovery against transferred assets and purchasers.
  • Retrospective municipal revaluation after IBC sale faces serious constraints: Even if a municipality has valuation powers under its Act, deploying them to generate liabilities for pre-transfer periods and recover them from the auction purchaser is likely to be struck down as inconsistent with IBC process discipline.
  • “As is where is” clauses are not a universal answer: The decision narrows reliance on such clauses in IBC liquidation sales, especially where statutory demands were not crystallized at sale and where the authority bypassed the liquidator.
  • Increased transactional certainty for IBC auction purchasers: The ruling strengthens purchaser confidence that latent municipal demands cannot later be manufactured and enforced against them for historical periods, improving marketability and value realization in liquidation auctions.
  • Open-textured questions on “statutory charge” and “security interest” remain fact-sensitive: By clarifying that it is not extinguishing charges “abstractly,” the Court signals future disputes may turn on whether and how a municipal charge qualifies and is asserted under Sections 52/53—yet the procedural requirement to come through the liquidator remains central.

4. Complex Concepts Simplified

“Operational debt” (Section 5(21) IBC)
A category of debt that includes statutory dues payable to Government/local authorities. Property tax dues generally fall here, meaning they must be processed in insolvency/liquidation like other operational claims.
“Waterfall mechanism” (Section 53 IBC)
A statutory order in which liquidation proceeds are distributed (costs first, then secured creditors/workmen, employees, and so on). Government and local authority dues cannot bypass this order by using their own statutes once liquidation is underway.
“Clean slate principle”
The idea that a new acquirer should not be hit by unknown/undecided historical claims after an insolvency process. In this judgment, the Court adapted that logic to liquidation by insisting that enforcement of past dues must occur through IBC processes, not against the purchaser.
Non-obstante clause (Section 238 IBC)
A legislative override: if another law conflicts with the IBC, the IBC prevails to the extent of inconsistency.
“As is where is / whatever there is”
A sale condition meaning the buyer takes the asset in its existing physical/legal condition. This judgment holds such clauses cannot be used to defeat mandatory IBC claim-handling and cannot convert a later-created retrospective demand into a transferred “encumbrance.”
“Statutory charge” vs. enforcement
Even if a law creates a charge over property for unpaid tax, the Court emphasized that enforcing it (especially post-liquidation sale) must conform to IBC procedures and priorities; otherwise, it cannot be pressed against the auction purchaser.

5. Conclusion

This judgment crystallizes a practical rule for IBC liquidation sales: municipal authorities cannot retrospectively revalue property and recover pre-liquidation/pre-transfer property tax from IBC auction purchasers when they failed to assert claims within the liquidation process. The Court places decisive weight on the IBC’s overriding effect (Section 238), the classification of municipal dues as operational debt (Section 5(21)), and the mandatory waterfall distribution (Section 53).

Equally important is the judgment’s careful calibration: it does not announce a sweeping extinction of statutory charges in the abstract, but it makes clear that enforcement is procedurally and hierarchically constrained by the IBC—thereby protecting liquidation value and purchaser certainty while compelling statutory creditors to participate in the insolvency framework.
