They already won. The Supreme Court changed the law. They lost.

Two Shots at the Same Land: How the Supreme Court Reopened Settled Acquisition Cases

When the Government of NCT of Delhi and the Delhi Development Authority (DDA) approached the Supreme Court in 2021, they were not appealing a fresh loss. They were trying to undo a loss they had already suffered—and lost—years earlier. The landowners, M/s BSK Realtors LLP and others, had already won. The High Court of Delhi had declared their land acquisition lapsed in 2016. The DDA had appealed to the Supreme Court and lost in 2016. The matter was closed. Or so the landowners thought.

What changed? A Constitution Bench of the Supreme Court itself, in Indore Development Authority v. Manoharlal (2020) 8 SCC 129, overruled the very precedent on which those High Court orders were based. The Government now wanted a second chance to argue that the acquisitions had never lapsed. The stakes were enormous: hundreds of acres of land in Delhi, infrastructure projects worth crores, and the fundamental legal principle that a judgment, once final, stays final.

The 2016 Victory That Vanished

The story begins under the old law. The Government of Delhi and the DDA had issued notifications under Section 4(1) of the Land Acquisition Act, 1894, acquiring large tracts of land for public purposes. The new law—the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013—came into force on January 1, 2014. Its Section 24(2) contained a deemed lapse provision: if the acquisition under the old Act had not been completed—meaning compensation not paid or possession not taken—the proceedings would lapse.

In 2014, the Supreme Court decided Pune Municipal Corporation v. Harakchand Misirimal Solanki (2014) 3 SCC 183. It interpreted the word "or" in Section 24(2) literally: either non-payment of compensation or non-taking of possession would cause the acquisition to lapse. Armed with this, landowners in Delhi rushed to the High Court. On January 11, 2016, the Delhi High Court allowed their writ petitions, declaring the acquisitions lapsed under Section 24(2). The DDA appealed to the Supreme Court. On August 31, 2016, the Supreme Court dismissed the appeals. It granted the DDA one year's liberty to initiate fresh acquisition, but the lapse stood.

That should have been the end. It was not.

The Constitution Bench That Changed Everything

On March 6, 2020, a five-judge Constitution Bench in Indore Development Authority v. Manoharlal overruled Pune Municipal Corporation. The Court held that the word "or" in Section 24(2) must be read as "and". Both conditions—non-payment of compensation and non-taking of possession—must be satisfied for the acquisition to lapse. The earlier interpretation was wrong. The legal landscape shifted overnight.

The Government of NCT of Delhi and the DDA saw their opening. They filed fresh Special Leave Petitions (SLPs) in 2021, challenging the very same High Court orders that had been upheld by the Supreme Court in 2016. The landowners objected. They argued the doctrine of merger: once the Supreme Court dismissed the DDA's appeal in 2016, the High Court order merged into the Supreme Court's order. You cannot challenge a merged order. They also raised res judicata: the issue had been heard and finally decided. The Government's SLPs, they said, were an abuse of process.

A two-judge bench referred the matter to a three-judge bench on July 21, 2022, recognizing that the interplay between merger, res judicata, and the effect of an overruled precedent required deeper examination.

What Each Side Argued

The Government of NCT of Delhi and the DDA argued that the change in law was fundamental. The Pune Municipal Corporation interpretation was the sole basis for the High Court orders. Once that foundation was removed, the orders could not stand. They relied on Mathura Prasad Bajoo Jaiswal v. Dossibai N.B. Jeejeebhoy (1970) 1 SCC 613, which held that res judicata does not apply when the law has been altered since the earlier decision on a pure question of law. They also argued that the DDA and the Government were co-respondents in the first round, with no conflicting interests, so res judicata could not operate between them.

The landowners countered with Kunhayammed v. State of Kerala (2000) 6 SCC 359, which established that once the Supreme Court grants leave and decides an appeal, the doctrine of merger applies. The High Court order merges into the Supreme Court's order. You cannot file a fresh challenge to the merged order. They also argued that the Government had suppressed the fact of the first round of litigation in its SLPs, which should warrant dismissal on that ground alone.

The Doctrine That Did Not Bar the Door

The Court, authored by Justice Dipankar Datta with Justice Surya Kant and Justice Ujjal Bhuyan concurring, first tackled res judicata. It examined Munni Bibi v. Tirloki Nath (AIR 1931 PC 114), which laid down three conditions for res judicata between co-defendants: there must be a conflict of interest, the court must have been necessary to decide that conflict, and the decision must be final. Applying State of Gujarat v. M.P. Shah Charitable Trust (1994) 3 SCC 552, the Court found that the DDA and the Government of NCT of Delhi were co-respondents in the first round with no conflicting interests. No issue between them was directly and substantially in dispute. The Court had not adjudicated any dispute between them. Res judicata did not apply.

On the merger doctrine, the Court acknowledged Kunhayammed as good law. The merger had occurred. But the Court carved an exception. It held that the extraordinary power under Article 142 of the Constitution—the power to do complete justice—is preserved as an exception to the doctrine of merger and stare decisis. This power can be invoked in sui generis situations where inconsistent judicial outcomes affect public interest. The Court was careful to note that this exception should be invoked only in the rarest of rare cases and sparingly.

On the suppression argument, the Court held that non-disclosure of a prior round of litigation by another authority (the DDA) did not constitute suppression of material fact warranting dismissal, where that prior dismissal would not affect the merits of the present case.

The Witness Rule the Supreme Court Applied

The Court then turned to the substantive issue: who could claim a lapse under Section 24(2)? It reaffirmed Shiv Kumar v. Union of India (2019) 10 SCC 229, which held that subsequent purchasers—those who buy land after the Section 4(1) notification—lack locus to seek a declaration of lapse. A sale after the notification is void ab initio under the Delhi Lands (Restrictions on Transfers) Act, 1972. The Court expressly overruled Govt (NCT) of Delhi v. Manav Dharam Trust (2017) 6 SCC 751, which had held otherwise.

The Court then classified the landowners into five groups (A through E) based on their status and the stage of litigation. For Groups A, B.1, and C.1—where the landowners were original owners or had not been found to be subsequent purchasers—the Court directed fresh acquisition within one year from August 1, 2024. The compensation would be calculated under the 2013 Act at the market value as of January 1, 2014. The Court dispensed with several provisions of the 2013 Act, including Chapters II, III, and V, to enable expedited acquisition. Status quo on possession, land use, and third-party rights was directed.

For Groups C.2 and C.3—where the landowners were subsequent purchasers—the Court allowed the Government's appeals, set aside the High Court orders, and upheld the acquisitions. For Group B.2, the appeals were dismissed as infructuous. Group D was de-tagged for separate listing. Group E was remitted to the High Court for fact-finding on fraud and title disputes.

THE PLAY: If you are a government authority facing a res judicata or merger bar after a change in law, argue that the extraordinary power under Article 142 can be invoked to do complete justice, but only in the rarest of rare cases where inconsistent outcomes affect public interest and the foundational precedent has been overruled.

Why This Matters in Practice

For advocates, this judgment is a masterclass in the limits of res judicata and merger. The Court has clarified that res judicata does not operate between co-respondents who had no conflicting interests. It has also confirmed that a change in law on a pure question of jurisdiction can negate res judicata, following Mathura Prasad. But the real weapon is Article 142. The Court has opened a narrow window for reopening settled matters where the foundational precedent has been overruled and public interest demands uniformity.

For CFOs and founders holding land that was acquired under the old Act, this judgment is a warning. If you purchased land after the Section 4(1) notification, your title is void ab initio. You cannot claim a lapse under Section 24(2). Even if you won a High Court order based on Pune Municipal Corporation, that order can now be reopened if the government invokes Article 142. The only safe path is to ensure that the acquisition is completed—both compensation paid and possession taken—or to negotiate a fresh acquisition under the 2013 Act.

For the Government of Delhi and the DDA, this judgment is a lifeline. It allows them to restart acquisition for infrastructure projects that were stalled by the Pune Municipal Corporation interpretation. But the clock is ticking: fresh acquisition must be completed within one year from August 1, 2024. The compensation will be at 2014 market values, which may be significantly higher than the original compensation under the 1894 Act.

The Bottom Line

If you are a landowner who won a lapse declaration under Pune Municipal Corporation, your victory is not final—the government can reopen it under Article 142, but only if the public interest in infrastructure projects outweighs your individual right to finality, and only if you are not a subsequent purchaser.
