Supreme Court Clarifies Power Purchase Agreement-Contractual Obligations Cannot Be Diluted
October 25, 2025Supreme Court on 25th September 2025 in DDA v. Corporation Bank (2025 INSC 1161) calrified Public Law Principles while protecting an innocent buyer. It balanced res judicata, restitution, and auction law, ensuring justice was not sacrificed at the altar of technicalities
📖 The Story in Legal Factual Matrix
2001 – DDA allotted a leasehold plot at Jasola, Delhi to Sarita Vihar Club for building a sports/recreation club. Lease conditions required prior written consent of the Lt. Governor before any mortgage.
2002 – he Club took loan from Corporation Bank. Though DDA gave a limited “No Objection” to apply for loan, the mortgage was created without mandatory approval. The Bank sanctioned a higher loan than permitted. 2005 – Lease deed executed. The Bank claimed mortgage over the property and informed DDA, but no written consent was ever obtained.
2010 – Club defaulted. Bank approached Debt Recovery Tribunal (DRT), which issued Recovery Certificate. DDA was not impleaded despite its statutory rights.
2012 – DRT ordered e-auction. DDA objected citing lack of consent, but its objections were rejected. DDA even filed a writ in Delhi High Court, but withdrew it after the Bank gave an undertaking that the auction would comply with lease terms.
Nov 2012 – Auction held. M/s Jay Bharat Commercial Enterprises Pvt. Ltd. emerged as the highest bidder (₹13.15 crores against ₹8.85 crores reserve). Sale was confirmed and possession handed over.
2013-14 – DDA again challenged the auction, claiming its statutory dues and right of pre-emption. High Court dismissed writ on grounds of res judicata, saying earlier writ (withdrawn in 2012) barred a second round.
Appeal to Supreme Court – DDA argued the mortgage was void, auction illegal, and High Court wrongly applied res judicata. Auction Purchaser claimed innocence and refund.
📚Observations on Legal Propositions
1. Doctrine of Res Judicata in Writ Jurisdiction
The doctrine of Res Judicata rests on the foundation that once a matter has been finally heard and decided, it cannot be reopened between the same parties.In Daryao v. State of U.P., AIR 1961 SC 1457, a Constitution Bench held that principles of res judicata apply even to writ proceedings under Articles 32 and 226.Reiterated in Gulabchand Chhotalal Parikh v. State of Gujarat, AIR 1965 SC 1153, where the Court summarized that a dismissal of a writ petition on merits bars subsequent writs on the same cause, but dismissal for laches or alternate remedy does not.In the present case the Supreme Court clarified that if an earlier writ is withdrawn on an undertaking, without a decision on merits, res judicata does not bar a subsequent writ where a fresh cause of action arises due to breach of that undertaking.
2. Unjust Enrichment or Unjust Benefit
Any civilized legal system prohibits one party from retaining money or benefit obtained at the expense of another, when it is against conscience to retain it. In Fibrosa Spolka v. Fairbairn Lawson (1943 AC 32), the House of Lords recognized unjust enrichment as a distinct legal basis for restitution. Approved in Nagpur Golden Transport Co. v. Nath Traders (2012) 1 SCC 555, where the Court reiterated that restitution prevents a party from unjust enrichment. In the present case the Court applied this principle to hold that the Bank, having advanced money on an illegal mortgage and sold property it had no authority to sell, could not pass liability to the auction purchaser.
3. Principle of Restitution
Restitution is a corrective measure — restoring parties to their original position when one has suffered without fault. Recognized in South Eastern Coalfields Ltd. v. State of M.P. (2003) 8 SCC 648, where the Court held that restitution is inherent in every court and flows from Article 142 as well as inherent powers.In the present Case the Apex Court stressed that restitution is not just a legal remedy but a moral imperative.
4. Situation of an Auction Purchaser
Auction purchasers who enter proceedings in good faith are entitled to protection, particularly where they have neither committed breach nor default. In Janatha Textiles v. Tax Recovery Officer (2008) 12 SCC 582, it was held that once an auction is conducted following law, the purchaser’s rights cannot be unsettled, except where fraud or illegality is established.In the present Case the Supreme Court held that the auction purchaser was an innocent actor who entered in good faith.Since the auction itself was void for violation of Rule 53 of the Income Tax Second Schedule, the sale was quashed.Restitution required refund of the bid amount with 9% interest to the purchaser.
🏛️ The Supreme Court’s Verdict
- Auction & Sale Quashed: Held illegal as it violated lease conditions and Rule 53 of the Income Tax Second Schedule (non-disclosure of DDA’s statutory claim).
- Res Judicata Not Applicable: Earlier writ was withdrawn on Bank’s undertaking, hence no bar.
- Auction Purchaser Protected: Innocent, entered in good faith, hence entitled to refund of entire bid money with 9% interest.
- Bank Liable: Having acted on an illegal mortgage, Bank bore responsibility for consequences.
💡 Key Takeaway
- Res judicata applies only when earlier writ is decided on merits.
- No unjust enrichment can flow from an illegal mortgage.
- Restitution ensures innocent parties are not penalized.
- Auction purchasers stand protected in equity, even if the auction fails legally.
🌐 Impact on Public Auctions & Society
For Banks
- Must verify lease conditions and statutory claims before auction.
- Cannot shift burden of illegality onto auction purchasers.
For Auction Purchasers
- Assurance of judicial protection if sale is invalid.

For Society

- Ensures public authorities’ statutory rights (like unearned increase) are respected.
- Prevents erosion of public trust in the auction system.
