Arifur Rahman Khan v. DLF Southern Homes: the one-sided clause and the consumer's interest entitlement

Wing Cdr Arifur Rahman Khan v. DLF Southern Homes Pvt Ltd is the case that crystallised the one-sided clause doctrine in Indian real-estate consumer law months before its formal articulation in IREO Grace Realtech (P) Ltd v. Abhishek Khanna (January 2021). The two-judge bench of Dr D.Y. Chandrachud, J. and K.M. Joseph, J. — deciding on 24 August 2020 — held that the Apartment Buyer's Agreement's token delay-compensation clause (Rs 5 per square foot per month) could not operate as a cap on the consumer forum's remedial powers under the Consumer Protection Act 1986. The Court awarded 325 of the 339 appellant flat-buyers 6 per cent per annum simple interest on the entire amount paid from the expiry of the contractual 36-month possession window until the offer of possession — in addition to, not in substitution of, the contractual rate.

The judgment is reported at 2020 SCC OnLine SC 667. (The SCC print citation (2020) 16 SCC 512 is frequently quoted by secondary sources but is not independently verified for the purposes of this digest; the SCC OnLine cite is the safe primary handle.)

The reasoning is doctrinally significant in three registers. It treats the developer-consumer relationship as a "service" relationship under the CPA 1986 — distinguishing "housing-construction/building activity" (which is service) from a "simple transfer of land" (which is not). It reads the one-sided ABA against the consumer's bargaining position and refuses to enforce the contractual cap as a ceiling on remedies. And it confirms the standing of assignees and second-hand purchasers to maintain consumer complaints on the same footing as the original allottees.

A drafting caveat is in order at the threshold. The 6 per cent per annum simple interest rate awarded in Arifur Rahman Khan operates under the CPA route — as compensation for deficiency in service. It is distinct from the RERA interest formula crystallised in Newtech Promoters and Developers Pvt Ltd v. State of UP (2021), which works off the State-Rule prescribed MCLR-plus formula (in UP, MCLR + 1 per cent). The two routes are doctrinally parallel — each available at the allottee's election under Imperia Structures Ltd v. Anil Patni (2020) — but the quantification mechanics differ. Practitioners should plead the route to the appropriate formula.

The statutory architecture

The Consumer Protection Act 1986 — the governing statute in Arifur Rahman Khan — supplied three load-bearing categories.

Section 2(1)(d)'s definition of "consumer" extended to a person who hired or availed of services for consideration, including beneficiaries of the service. The bench-tested issue was whether assignees and second-hand purchasers — homebuyers who acquired the original allottee's rights by sub-contract or transfer rather than direct booking with the developer — fitted within "consumer". The judgment confirmed they did, on the reasoning that the assignor's rights and the assignee's interests were continuous in the housing-construction service stream.

Section 2(1)(g) defined "deficiency" as "any fault, imperfection, shortcoming or inadequacy" in the quality, nature, manner or performance of the service. Housing construction was within the "service" stream. Section 2(1)(r) defined "unfair trade practice" as a practice that, for promoting the sale, use or supply of any goods or services, adopted unfair or deceptive practices — the category that would become the analytical home for the one-sided-clause doctrine in IREO Grace. Section 21 conferred original jurisdiction on the NCDRC in claims exceeding the then-monetary threshold of Rs 1 crore and ample discretion to award compensation, refund and consequential reliefs.

The Apartment Buyer's Agreement supplied a 36-month contractual window for possession with a six-month grace period. The delay-compensation clause stipulated Rs 5 per square foot per month for any further delay. The contract was templated and offered on a take-it-or-leave-it basis to allottees. The asymmetry — between the developer's right to reset deadlines and the allottee's right to compensation at a token rate — was the textual basis for the one-sided-clause inquiry. The analogical extension to RERA operates through Section 18 and the Imperia Structures concurrent-forum line.

The factual matrix

The appellants were flat-purchasers in DLF's "Westend Heights" project in BTM Extension, Begur, Bengaluru. The Apartment Buyer's Agreements had been executed between 2008 and 2009. The contractual 36-month possession period — extended by a six-month grace window — expired between 2012 and 2013. Possession was not offered through 2014 and 2015. A substantial cohort of allottees approached the NCDRC under the Consumer Protection Act 1986.

The NCDRC held the developer liable for deficiency in service but limited the remedy to the contractual delay-compensation rate of Rs 5 per square foot per month. The allottees carried the matter to the Supreme Court. DLF cross-appealed on the maintainability of the consumer complaints by certain categories of appellants — including assignees, second-hand purchasers, and a sub-set whose agreements contained arbitration clauses.

A total of 339 appellants were before the Court. The bench worked through the factual matrix appellant-by-appellant and identified 14 whose claims could not be sustained on the materials — leaving 325 whose claims succeeded on the deficiency-in-service ground.

The Court's reasoning

The judgment works on four tracks: the construction of the developer-allottee relationship as a "service" relationship; the treatment of the contractual delay-compensation clause; the quantification of the consumer remedy; and the rejection of the maintainability objections.

Housing construction is "service"

Chandrachud, J. anchored the consumer character of the dispute on the housing-construction analytical line. The DLF developer-allottee relationship was not a "simple transfer of land" — a category of dealings that earlier authority had read out of the CPA's service-coverage. It was an integrated housing-construction activity, in which the developer assembled the land, designed the project, marketed the units, collected progress payments and undertook the construction. The "service" was the bundle of housing-construction obligations; possession was the end-point of that service. Failure to deliver within the contractual window was therefore a deficiency.

The distinction between simple land transfer and housing-construction had been worked through in earlier NCDRC and Supreme Court authority. The judgment did not unsettle that line; it confirmed the housing-construction characterisation for DLF-style integrated residential projects.

The one-sided delay-compensation clause is not a ceiling

The doctrinal centre of the case is the treatment of the Rs 5 per square foot per month clause. Chandrachud, J. held that the contractual stipulation was on the developer's standard terms; that the allottee had no negotiating power on the clause; that the rate was, in real-world terms, derisory in relation to the carrying cost of the amounts paid by the allottee over the period of delay; and that the clause could not operate as a cap on the consumer forum's remedial powers under the CPA.

The reasoning generalises beyond the particular rate. A contractual delay-compensation clause that is the product of a templated take-it-or-leave-it agreement, that operates asymmetrically as between developer and allottee, and that bears no reasonable relation to the carrying cost of the allottee's payments, is unenforceable as a ceiling. The contractual rate operates as a floor only. The consumer forum may, on its independent assessment, award just and reasonable compensation that exceeds the contractual rate.

The reasoning anticipates — in operative terms but without the formal labelling — the one-sided-clause doctrine that Indu Malhotra, J. would crystallise in IREO Grace Realtech (P) Ltd v. Abhishek Khanna on 11 January 2021. The IREO Grace judgment is the formal articulation; Arifur Rahman Khan, delivered some four-and-a-half months earlier, is the operative precursor.

The 6 per cent per annum simple interest measure

The Court calibrated the compensation at 6 per cent per annum simple interest on the entire amount paid by each appellant, running from the expiry of the contractual 36-month period (with grace) until the offer of possession. The award was framed as compensation under the CPA route and was payable in addition to — not in substitution of — the contractual rate.

The 6 per cent figure was the Court's assessment of a just and reasonable measure on the materials before it. It is not a fixed rule of universal application: Arifur Rahman Khan does not freeze the quantum at 6 per cent. The bench-determined rate operates as a benchmark — the consumer forum retains discretion to calibrate the rate to the particular facts. Later cases under the CPA and the RERA routes have used varying figures.

The two-route distinction matters here. Arifur Rahman Khan operates under the CPA and the rate is the bench-determined just-and-reasonable measure. Newtech Promoters (2021) operates under RERA and the rate is the State-Rule formula (MCLR + 1 per cent in UP). Allottees who have a choice of route — preserved by Imperia Structures and now refined by the election-of-remedies discipline of Kabra and Associates v. Hemdev (2026) — should plead the route to the formula they want.

Maintainability — assignees, arbitration clauses, multiple appellants

DLF had raised three maintainability objections. The first concerned assignees and second-hand purchasers — homebuyers who had acquired the original allottee's interest. The Court held that the assignee acquired the same rights as the original allottee on the housing-construction service stream; the assignee's standing as a "consumer" was not defeated by the intermediate transfer. The reasoning aligns with the legislative purpose of the CPA — protection runs to the beneficiary of the service, not narrowly to the contracting allottee.

The second objection concerned arbitration clauses in certain ABAs. The Court declined to enforce reference to arbitration on the Aftab Singh line — Emaar MGF Land Ltd v. Aftab Singh (review judgment, 10 December 2018) — under which an arbitration clause does not displace the consumer forum's jurisdiction.

The third objection concerned the 14 appellants whose claims were on the materials not sustainable — for reasons individual to those claims, including agreements that were subject to specific terms that did not engage the deficiency-in-service framework on the same footing. The Court held the 14 out and granted the relief to the remaining 325.

The doctrinal contribution

Arifur Rahman Khan did three pieces of doctrinal work.

It crystallised the one-sided clause doctrine in real-estate ABA jurisprudence. The contractual delay-compensation cap was rejected as a ceiling on the consumer forum's remedial powers; the contractual rate is a floor only. The reasoning travelled directly into IREO Grace Realtech v. Abhishek Khanna (January 2021), which gave the doctrine its formal label and articulation under Section 2(1)(r) of the CPA 1986.

It supplied the bench-determined 6 per cent per annum simple interest measure under the CPA route — distinct from, and doctrinally parallel to, the State-Rule MCLR-plus formula that Newtech Promoters (2021) would later confirm under the RERA route. The two-route distinction has held through the post-2021 jurisprudence and continues to govern the choice of formula.

It confirmed the standing of assignees and second-hand purchasers as "consumers" under Section 2(1)(d) of the CPA 1986. The reasoning operates as a precedent on the wider question of homebuyer standing — including, by analogical extension, on the standing of secondary-market homebuyers under Section 18 of RERA and as financial creditors under Section 5(8)(f) of the IBC 2016.

What the judgment did not decide

Three matters require flagging.

The interaction of the CPA and RERA routes on quantification. Arifur Rahman Khan did not directly address whether an allottee who has elected the consumer-forum route is entitled to invoke the RERA Authority's formula (MCLR + 1 per cent in UP) on the same dispute. The post-2020 architecture — through Imperia Structures and now Kabra and Associates v. Hemdev (2026) — vests the election in the allottee and operates one route at a time. The cross-loading of formula across routes is foreclosed in practice by the election-of-remedies discipline.

The treatment of secondary-market purchasers under RERA. The Arifur Rahman Khan confirmation of assignee standing operates squarely under the CPA. Whether the same standing extends under Section 18 of RERA — and whether the RERA Authority must entertain complaints by purchasers who acquired the unit by sub-contract from the original allottee — is a question the judgment touches but does not settle. Newtech Promoters (2021) confirmed the RERA Authority's plenary jurisdiction but did not address the assignee question directly.

The contours of "deficiency" in mixed-cause delays. The judgment treats the delay as a deficiency-in-service simpliciter. Where the delay is attributable to force majeure events, regulatory bottlenecks, or third-party defaults not within the developer's control, the deficiency-in-service inquiry becomes more textured. Arifur Rahman Khan did not work through the mixed-cause case; the post-COVID jurisprudence has had to develop the analytical structure on a case-by-case basis.

The doctrinal arc

The doctrinal line in which Arifur Rahman Khan sits runs through three phases.

The pre-Arifur Rahman Khan phase had built up the housing-construction-as-service line through a series of NCDRC and Supreme Court decisions but had not yet crystallised the one-sided-clause framework. Emaar MGF Land Ltd v. Aftab Singh (December 2018) had preserved the consumer-forum route against arbitration clauses. The token delay-compensation clauses in templated ABAs were, in practice, being applied as caps.

Arifur Rahman Khan (August 2020) marked the operative break. The 6 per cent simple interest award and the one-sided-clause reasoning crystallised the doctrine in working terms. Imperia Structures Ltd v. Anil Patni (November 2020) followed with the concurrent-forum rule for the RERA-CPA interface. IREO Grace Realtech (P) Ltd v. Abhishek Khanna (January 2021) gave the one-sided-clause doctrine its formal articulation under Section 2(1)(r) and absorbed Arifur Rahman Khan's reasoning into the unfair-trade-practice frame.

Newtech Promoters (November 2021) supplied the parallel RERA-route architecture: retroactive (not retrospective) application of RERA to ongoing projects, plenary jurisdiction of the RERA Authority, and the State-Rule MCLR-plus interest formula. Experion Developers Pvt Ltd v. Sushma Ashok Shiroor (April 2022) added the refinement that the allottee may elect, at the remedy stage, between full refund with interest and possession with delay compensation. Kabra and Associates v. Hemdev (2026) then overlaid the election-of-remedies discipline on the RERA-CPA concurrent set, narrowing Imperia Structures's allowance of concurrent recourse into a one-time-election rule.

What practitioners take

For the allottee under the CPA route. The Arifur Rahman Khan one-sided-clause reasoning is the working tool. The pleading should isolate the templated character of the ABA, the asymmetry of the delay-compensation clause, and the disproportion between the contractual rate and the carrying cost of the amounts paid. The 6 per cent per annum simple interest rate is the bench-determined benchmark — but the consumer forum retains discretion. The contractual rate is preserved as a floor; consequential reliefs (refund, registration charges, taxes) follow as the case requires.

For the allottee under the RERA route. The Newtech Promoters MCLR-plus formula (read with the State Rules) applies. Quantification is distinct from the CPA route. The RERA Authority's plenary jurisdiction under Section 31 is the gateway. After Kabra and Associates v. Hemdev (2026), election to the RERA route is one-way; the CPA route is foreclosed on the same cause of action.

For the developer. The one-sided clause is no defence to a delay claim. The pleading must focus on factual contestations — the actual date of completion, the genuine offer of possession, the apportionment of fault for force-majeure or regulatory delays. Pleadings that rest on the contractual delay-compensation cap as a ceiling are foreclosed by Arifur Rahman Khan; pleadings that focus on the mixed-cause analysis remain available.

For drafting going forward. Templated delay-compensation clauses at token rates are unenforceable as ceilings. ABAs being drafted in 2026 should set the delay-compensation rate at a level that bears reasonable relation to the carrying cost of allottee payments — otherwise the consumer forum will, applying Arifur Rahman Khan, supersede the contractual rate. The symmetric drafting discipline — the developer's right to cancellation and the allottee's right to delay compensation on parallel terms — is the post-IREO Grace working standard.

For the assignee. Assignee and secondary-market homebuyer standing is preserved under Arifur Rahman Khan; the assignee acquires the same rights as the original allottee on the housing-construction service stream. The pleading should set out the chain of assignment and the consideration paid, but the standing question is foreclosed in the assignee's favour.
