Newtech Promoters v. State of UP: RERA's retroactive application to ongoing projects upheld

Newtech Promoters and Developers Pvt Ltd v. State of UP is the Supreme Court's definitive ruling on the constitutional and statutory architecture of the Real Estate (Regulation and Development) Act 2016. The judgment was delivered on 11 November 2021 by a three-judge bench of Uday Umesh Lalit, J., Ajay Rastogi, J., and Aniruddha Bose, J., with the lead opinion authored by Rastogi, J. It answers five framed questions that together constitute the constitutional spine of the RERA regime — the most consequential of them being the retroactive-versus-retrospective question on the application of the Act to "ongoing projects".

The judgment is reported at 2021 SCC OnLine SC 1044 and LL 2021 SC 641. The reasoning runs across four interlocking branches — the substantive retroactive-application question, the Section 43(5) pre-deposit-on-appeal question, the Section 31 single-member-adjudication question, and the Section 18 refund-with-interest formula question — and supplies the constitutional anchor on which the regulatory architecture of the RERA Authorities and the Appellate Tribunals has operated.

The statutory architecture

The constitutional and statutory architecture engaged by the judgment can be set out at the outset.

The substantive scope of the Act is anchored on the definition of "ongoing project" worked out by reference to Section 2(h), Section 3, and Section 5(3). The first proviso to Section 3(1) exempts from registration projects for which a completion certificate has been issued before commencement of the Act on 1 May 2017; the implication is that projects without a completion certificate — even those launched before 1 May 2017 — are within the registration net. That is the textual hook on which the "ongoing project" architecture is built.

The developer's substantive obligations are anchored on Section 11 (functions and duties — registration, advertising, model agreement, compliance with the sanctioned plan, conveyance) and Section 13 (10%-deposit limit on pre-agreement collections). The substantive entitlement of the allottee is Section 18: where the developer fails to complete or to give possession in accordance with the agreement, the allottee is entitled (a) to withdraw and claim refund with interest plus compensation, or (b) where the allottee does not withdraw, to receive interest for every month of delay until handover. Section 19(4) mirrors that right.

The adjudicatory architecture is anchored on Section 31 (complaint to the Authority), Section 32 (regulatory functions), the Section 71/Section 72 architecture for the Adjudicating Officer on compensation, and Section 43 — including the proviso to Section 43(5) requiring a promoter, on appeal, to deposit not less than 30% of the penalty (or such higher percentage as may be prescribed) or to pay the total amount due to the allottee with interest and compensation before the appeal is entertained.

The constitutional challenges engaged Article 14 (the discrimination challenge to retroactive application and pre-deposit), Article 19(1)(g) (freedom of trade), and Article 20(1) (retrospective penal liability). The state rule-making power supplied Rule 15 of the UP RERA Rules 2016, prescribing the interest rate at State Bank of India MCLR plus 1% per annum.

The factual matrix

The facts are the standard pattern of promoter-side challenges to RERA across multiple petitioners in the UP RERA jurisdiction. The promoters had launched projects — primarily in Greater Noida — before 1 May 2017 but had not obtained completion certificates by that date. The projects fell within the "ongoing project" net under the UP RERA Rules 2016. The UP RERA Authority had registered the projects, received allottee complaints, and passed refund-with-interest orders under Section 18.

The promoters challenged the application of the Act to pre-May-2017 projects (alleged infringement of Article 20(1) and Article 14), the Section 43(5) pre-deposit requirement (Article 14 and Article 19(1)(g)), and the Authority's single-member adjudication of Section 18 refund-with-interest claims (asserted to be in the Adjudicating Officer's exclusive jurisdiction under Section 71). The matter reached the Supreme Court on a batch of appeals from the Allahabad High Court's decision upholding the UP RERA architecture. The Bench framed five questions and answered them in turn.

The Court's reasoning

Retroactive, not retrospective

The first and most consequential branch is the retroactive-versus-retrospective question. Rastogi, J. worked through the doctrinal distinction with care. A retrospective statute alters the legal characterisation, rights or liabilities attaching to transactions completed before commencement — it reaches backward into closed transactions and reassigns their consequences. A retroactive statute operates from commencement onward but takes within its operation transactions that began before commencement and remain ongoing at commencement. The distinction has been worked through in the line beginning with Govind Das v. Income Tax Officer (1976) and reaffirmed in Hitendra Vishnu Thakur v. State of Maharashtra (1994).

Applied to RERA, the architecture of Section 3 and its proviso, read with the "ongoing project" definition, operates on the latter footing. The Act does not reopen completed projects; it operates on projects begun before 1 May 2017 but remaining ongoing — without a completion certificate — at that date. The substantive obligations — registration, disclosure, the Section 18 entitlement, the deposit limits — operate from commencement onward on the ongoing project as it stood at commencement.

The architecture is constitutionally permissible. Article 20(1) operates on penal retrospective liability and does not bar the imposition of regulatory architecture on ongoing transactions; the substantive provisions are regulatory and remedial, not penal. Article 14 is not infringed because the classification — projects with completion certificates exempt, projects without within the net — bears a rational nexus to the regulatory objective of protecting allottees where performance remains to be discharged. The output is the foundational holding on which the RERA Authorities have operated across the country.

The Section 43(5) pre-deposit proviso

The second branch addresses the Section 43(5) proviso — conditioning the entertaining of a promoter's appeal on the deposit of at least 30% of the penalty, or the total amount due to the allottee with interest and compensation. The Bench rejected the Article 14 and Article 19(1)(g) challenges. The promoter is the party that has incurred the substantive obligation and been found to have breached it; the allottee is the party in whose favour the obligation has crystallised. A pre-deposit requirement on the promoter's appeal — against the absence of such a requirement on the allottee's appeal — is a rational classification anchored on the differential substantive position of the two parties, bearing a rational nexus to the regulatory objective of securing the substantive realisation of allottee entitlements pending appellate scrutiny. On Article 19(1)(g) the Bench drew on the Government of Andhra Pradesh v. P. Laxmi Devi (2008) line and on the consumer-protection and tax-appellate-architecture lines in which pre-deposit requirements have been upheld as reasonable restrictions.

Single-member adjudication under Section 31

The third branch addresses the Authority's single-member adjudicatory power. The promoters had argued that the substantive monetary adjudication under Section 18 lay outside the Authority's power under Section 31 and within the Adjudicating Officer's exclusive jurisdiction under Section 71. The Bench rejected the argument and held that the Authority and the Adjudicating Officer operate concurrently — not in jurisdictional substitution. The textual hook is Section 31 read with Section 18: the allottee is empowered to complain to the Authority; the Authority is empowered to make findings of breach and to direct refund-with-interest. The Adjudicating Officer's jurisdiction under Section 71 is concurrent on the compensation component where additionally sought.

Section 18 refund-with-interest formula

The fourth branch addresses the interest-rate formula under Section 18 read with the state Rules. Rule 15 of the UP RERA Rules 2016 prescribes the rate at State Bank of India MCLR plus 1% per annum. The Bench upheld the state-rule architecture and held that the Section 18 entitlement crystallises at the rate prescribed by the state Rules. The formula is state-variable: the UP formula is MCLR + 1%; Haryana operates at MCLR + 2%; Maharashtra operates at the MahaRERA-prescribed rate. The state-variability is a feature of the architecture: the Act delegates the rate-fixing function to the appropriate Government, and the substantive entitlement is shaped at the state level.

The doctrinal contribution

Newtech Promoters is the constitutional anchor of the RERA regime. Its doctrinal contribution operates at four levels.

It supplied the definitive constitutional validation of the retroactive-application architecture. The substantive obligations of the Act reach into ongoing projects — projects begun before 1 May 2017 but not completion-certificated by that date — and the architecture is Article 14, Article 19(1)(g) and Article 20(1)-compliant. The architecture has become the foundation on which the RERA Authorities have operated across the country, and on which the substantive entitlement of allottees in ongoing projects has been worked out.

It confirmed the substantive unqualified character of the Section 18 refund-with-interest entitlement. Where the developer fails to complete or to give possession in accordance with the agreement, the allottee's right to withdraw and to claim refund-with-interest is substantive and unqualified — it does not turn on the developer's ability to pay, on the operational feasibility of refund, or on the substantive viability of the project. The Bench's reasoning operates as a robust anchor for the subsequent line of cases in which the substantive Section 18 right has been enforced against defaulting developers.

It upheld the Section 43(5) pre-deposit architecture for promoter appeals. The architecture has since become the operational filter through which speculative promoter appeals are screened out — a promoter's appeal that lacks substantive merit will not survive the pre-deposit requirement, and the architecture accordingly delivers operational efficiency to the appellate forum without infringing the substantive constitutional protections.

It established the concurrent operation of the RERA Authority and the Adjudicating Officer under Section 31 and Section 71 respectively. The architecture has since become the working framework for the allocation of complaints between the two regulatory bodies — the Authority handles the substantive findings of breach and the refund-with-interest consequences; the Adjudicating Officer handles the compensation component where additionally sought.

What the judgment did not decide

The Bench was deliberate in restricting its reasoning to the five framed questions. Three adjacent questions were not addressed and have been worked through in subsequent decisions.

It did not address the interaction between RERA and the Consumer Protection Act fora — the question of whether an allottee can simultaneously or in the alternative invoke the consumer forum under the CPA alongside the RERA Authority. That question had been answered in Imperia Structures Ltd v. Anil Patni (2020) — see our digest — which held that the CPA forum is not ousted by Section 79 of RERA and that the choice of forum vests in the allottee. Newtech Promoters does not displace that holding; the two judgments operate on complementary axes.

It did not address the substantive limits of the developer's defences against the Section 18 refund-with-interest claim — for instance, the question of whether a force-majeure event, a regulatory non-cooperation, or a planning-permission delay can constitute a defence to the substantive entitlement. The Bench's reasoning treats the entitlement as substantively unqualified at the level of the constitutional architecture; the fact-specific defences have been worked through case-by-case in the subsequent RERA Authority and Appellate Tribunal jurisprudence.

It did not address the interaction between RERA and the Insolvency and Bankruptcy Code 2016 CIRP route. That interaction had been substantively worked out in Pioneer Urban Land and Infrastructure Ltd v. Union of India (2019) — homebuyers as financial creditors under Section 5(8)(f), triple-forum doctrine across RERA, CPA and IBC — and has been further developed in the project-wise CIRP architecture under the IBC Amendment Act 2026. Newtech Promoters operates on the RERA-side of the interface and does not engage the IBC architecture.

The doctrinal arc

The Newtech Promoters line has had three phases.

The first, immediately post-Newtech, was consolidation. RERA Authorities across the country drew on the constitutional anchor to reinforce their jurisdiction over ongoing projects; Appellate Tribunals enforced the Section 43(5) pre-deposit requirement; High Courts disposed of pending challenges.

The second, through 2022-2024, was substantive elaboration. Experion Developers v. Sushma Ashok Shiroor (7 April 2022, Hima Kohli and Nagarathna JJ.) extended the substantive reasoning into the NCDRC and consumer-forum architecture, articulating the option for the allottee between full refund and possession-with-delay-compensation. IREO Grace Realtech (P) Ltd v. Abhishek Khanna (11 January 2021, Indu Malhotra and Indira Banerjee JJ.) had earlier articulated the one-sided-clause doctrine that operates alongside the Newtech architecture.

The third, from 2025 into 2026, has been operational recalibration. Kabra and Associates v. Hemdev (4 February 2026) sharpened the election-of-remedies discipline between RERA and CPA fora. Alpha Corp Development Pvt Ltd v. Greater Noida Industrial Development Authority (5 May 2026) — see our digest — extended the substantive resolution-objective reasoning to SPV-structured developers in CIRP. The RERA amendments under the Jan Vishwas Act 2026 (commencement 7 May 2026) substituted Section 68 and continued the decriminalisation policy. Newtech Promoters remains the constitutional anchor through which the architecture has held.

What practitioners take

For the allottee bringing a Section 18 claim. The substantive entitlement is unqualified at the constitutional level; the pleading should anchor the breach, the substantive election (refund-with-interest on withdrawal, or interest-for-delay without withdrawal), and the state-specific interest formula. The choice of forum — RERA Authority under Section 31 for refund-with-interest, Adjudicating Officer under Section 71 additionally for compensation where sought — should be worked out at the pleading stage. Post-Kabra v. Hemdev (2026) the election between the RERA forum and the CPA forum should be made deliberately.

For the promoter resisting a Section 18 claim. The constitutional defences from pre-Newtech litigation are no longer available. The defensive architecture must operate at the fact-specific level — disputing the breach, the substantive election, the quantum, and the operational arrangements. On appeal, the Section 43(5) pre-deposit must be discharged before the Tribunal will entertain the appeal.

For the developer at the project-launch stage. The "ongoing project" architecture is a substantive risk — a project that begins before the relevant date but does not complete in the projected timeline falls within the obligation net. Substantive compliance discipline — registration, disclosure, the 10% deposit limit, the Section 18 entitlement crystallising on delay — should be built into project economics at launch.

For the lender providing project finance. The Section 18 entitlement operates as a substantive senior-claim against project receivables on delay. The recovery architecture should anticipate it through escrow arrangements, monitoring covenants, and the structuring of the project-receivables waterfall, rather than assuming subordination to first-charge interests.

For the broader doctrinal posture. Newtech Promoters remains the constitutional spine of the RERA regime in India. Read alongside Imperia Structures, Pioneer Urban, and Bikram Chatterji v. Union of India — see our digest — it supplies the constitutional architecture in which homebuyer-protection litigation operates. The 2026 amendments have refined rather than displaced the architecture.
