Primacy of Section 27 Tribunal and Limits on Writ Interference in Coal Mine Performance Security: Commentary on Vedanta Ltd v. Nominated Authority, Ministry of Coal

Primacy of Section 27 Tribunal and Limits on Writ Interference in Coal Mine Performance Security: Commentary on Vedanta Limited v. Nominated Authority, Ministry of Coal & Ors., 2025 DHC 10744

I. Introduction

The judgment in Vedanta Limited v. The Nominated Authority, Ministry of Coal, Government of India & Ors., 2025 DHC 10744, delivered by the Delhi High Court (Justice Amit Sharma) on 2 December 2025, sits at the intersection of three important strands of public and commercial law:

  • The coal mine commercial auction regime under the Coal Mines (Special Provisions) Act, 2015 (“CM(SP) Act”) and CMDPAs;
  • The law on writ jurisdiction vis-à-vis statutory alternative remedies, particularly Section 27 of the CM(SP) Act and the exclusive role of the Tribunal constituted under the Coal Bearing Areas (Acquisition and Development) Act, 1957; and
  • The well‑settled jurisprudence on unconditional bank guarantees and performance securities, and the narrow grounds on which courts may restrain their encashment.

Vedanta challenged an order dated 21 July 2025 by the Nominated Authority appropriating 10% (about Rs. 29.23 crores) of its Performance Bank Guarantee (“PBG”) under a Coal Mine Development and Production Agreement (“CMDPA”) for the Radhikapur (West) Coal Mine in Odisha. The appropriation was premised on alleged delay in achieving Milestone‑3 (MS‑3) — primarily obtaining Environment Clearance (EC) — within the time limits in Schedule D (“Efficiency Parameters”) of the CMDPA.

The writ petition sought:

  • Quashing of the appropriation order;
  • A restraint on giving effect to the appropriation and refund of any amount appropriated;
  • Extension of milestone timelines and a change in the “Zero Date” under the CMDPA; and
  • Directions for time-bound processing of statutory clearances.

The Court, however, declined to adjudicate the merits and instead directed Vedanta to avail its statutory remedy before the Section 27 Tribunal, while continuing interim protection over the PBG for a limited period to enable such recourse.

The decision consolidates and extends the Delhi High Court’s earlier Division Bench ruling in Trimula Industries Limited v. Union of India, Ministry of Coal, 2024 SCC OnLine Del 3350, making it clear that disputes over CMDPA milestones, efficiency parameters, and PBG appropriations are to be channelled primarily to the statutory Tribunal, not to be routinely entertained in writ jurisdiction. Simultaneously, the Court reaffirms the strict standard for interference with unconditional bank guarantees.

II. Summary of the Judgment

1. Procedural outcome

The Delhi High Court:

  • Disposed of the writ petition without deciding the substantive contractual and factual disputes;
  • Held that Vedanta has an alternate efficacious statutory remedy under Section 27 of the CM(SP) Act before the Tribunal at Talcher, Odisha, which is functional;
  • Directed Vedanta to approach the Tribunal within 10 days under Section 27;
  • Extended the interim status quo order on the PBG only for those 10 days or until Vedanta approaches the Tribunal (whichever earlier), with a mandate to keep the PBG alive; and
  • Expressly clarified that it has expressed no opinion, even prima facie, on the merits of the rival claims.

2. Key legal holdings

  1. Bank Guarantee Encashment: The Court recited and applied Supreme Court principles that:
    • Unconditional and irrevocable bank guarantees are independent contracts between bank and beneficiary;
    • Courts may restrain encashment only in narrow situations: fraud of an egregious nature, irretrievable injustice, or special equities;
    • On the facts, Vedanta’s case did not fall within these exceptions, especially given its own undertaking to operationalise the mine by 3 June 2025.
  2. Alternative Remedy and Section 27 Tribunal: Relying heavily on the Division Bench ruling in Trimula Industries, the Court held that:
    • Section 27 CM(SP) Act provides a specialised statutory forum for “any dispute … arising out of any issue connected with the Act”;
    • Questions about CMDPA efficiency parameters, computation of milestones, and propriety of PBG appropriation involve disputed questions of fact and contractual interpretation better suited to the Tribunal;
    • The existence and functionality of the Tribunal make the writ petition inappropriate, absent exceptional circumstances.
  3. High Court’s Residual Jurisdiction: While recognizing that Section 27(4) preserves the jurisdiction of High Courts and the Supreme Court, the Court reaffirmed that:
    • Availability of a statutory remedy does not oust jurisdiction but guides the exercise of discretion under Article 226;
    • Given the Division Bench precedent directly on Section 27 (i.e., Trimula), this Single Judge was bound to relegate the parties to the Tribunal.

III. Factual and Contractual Background (in Brief)

1. The coal block and CMDPA framework

  • Radhikapur (West) Coal Mine (Angul district, Odisha) was auctioned under the 11th tranche of commercial coal mine auctions pursuant to the CM(SP) Act.
  • Vedanta emerged as the successful bidder on 28 December 2020, offering 21% revenue share.
  • A Coal Mine Development and Production Agreement (CMDPA) was signed on 11 January 2021.
  • A Vesting Order was issued on 3 March 2021 under the CM(SP) Rules and Act, transferring:
    • Rights, title and interest in the mine;
    • The approved mining plan and associated approvals; and
    • Statutory clearances in favour of Vedanta (subject to certain conditions).
  • Vedanta furnished:
    • Upfront payment instalment of approx. Rs. 24.76 crores;
    • A PBG of Rs. 263.17 crores; and
    • Other required payments and submissions (commencement plan, etc.).

2. Milestones (Efficiency Parameters) and alleged delay

Schedule D to the CMDPA fixes Efficiency Parameters in the form of “Milestones” (MS‑1 to MS‑5), each with a specific completion timeframe. The key milestones in issue were:

  • MS‑2 – Approval of Mining Plan / Project Report;
  • MS‑3 – Obtaining Environment Clearance (EC) and Forest Clearance Stage‑II (FC‑II);
  • Subsequent milestones (MS‑4 and MS‑5) cover land acquisition/R&R and commencement of production (operationalisation).

Two Show Cause Notices (SCNs) were central:

  1. SCN‑I (8 February 2022) — alleging delay in achieving MS‑2 (primarily mining lease application / mining plan related aspects).
    • Vedanta responded, citing COVID‑19, boundary discrepancies, and other administrative bottlenecks.
    • The 18th Scrutiny Committee (23 August 2022) accepted Vedanta’s explanation, held that delay “cannot be attributed” to Vedanta, and recommended that penalty not be imposed and SCN‑I be waived (confirmed by letter dated 18 January 2023).
  2. SCN‑II (6 June 2024) — alleging non‑achievement of MS‑3 within schedule, particularly delay in obtaining EC and FC‑II.
    • Vedanta replied on 20 June 2024, blaming boundary coordinate discrepancies, change in land classification, elephant corridor issues, requirement to apply for fresh EC (instead of transfer), delays linked to the Model Code of Conduct, etc.
    • The 24th Scrutiny Committee (8–9 August 2024) did not immediately impose penalty but made a conditional recommendation:
      • Vedanta to give an undertaking to operationalise the mine before 3 June 2025;
      • If the mine is operationalised by that date, the SCN‑II would be reconsidered;
      • If not, penalty by way of PBG appropriation under CMDPA would be recommended.
    • Vedanta, by letter dated 12 August 2024, voluntarily gave the undertaking to operationalise the mine by the stipulated date.

Vedanta did not operationalise the mine by June 2025. The Nominated Authority then:

  • Issued the impugned appropriation order dated 21 July 2025, appropriating 10% of the PBG for failure to achieve MS‑3; and
  • Noted that EC was obtained on 23 January 2023, beyond the due date of 3 September 2022 as calculated by the Authority.

Vedanta, across its pleadings, also raised a cluster of other issues — boundary coordinate mismatch, DGPS survey and ORSAC data, change in forest area classification, elephant corridor and human‑elephant conflict, complications in transfer vs. fresh grant of EC, and assertion of force majeure under Clause 25 of the CMDPA.

IV. Precedents and Authorities Cited

1. Supreme Court on bank guarantees

The Court relied on classic bank guarantee jurisprudence:

(a) Himadri Chemicals Industries Ltd. v. Coal Tar Refining Co., (2007) 8 SCC 110

At paragraph 14 (quoted), the Supreme Court distilled the principles governing injunctions against encashment of bank guarantees/letters of credit:

  1. In commercial dealings, where an unconditional bank guarantee is given, the beneficiary is entitled to realise it irrespective of pending disputes.
  2. The issuing bank is bound to honour the guarantee as per its terms.
  3. Courts should be slow in granting injunctions restraining realisation.
  4. Because the guarantee is an independent, absolute contract, disputes under the underlying contract are not grounds for injunction.
  5. Only fraud of an egregious nature vitiating the foundation of the guarantee, or
  6. Irretrievable harm/injustice, can justify restraint.

(b) Standard Chartered Bank v. Heavy Engineering Corporation Ltd., (2020) 13 SCC 574

Reaffirming the autonomous nature of bank guarantees, the Supreme Court held:

“…once the demand was made in due compliance with bank guarantees, it was not open for the appellant Bank to determine as to whether the invocation of the bank guarantee was justified so long as the invocation was in terms of the bank guarantee… in absence [of fraud/irretrievable injustice/special equities], it is not even open for the Court to interfere with the invocation and encashment…”

(c) Jindal Steel and Power Ltd. & Anr. v. Bansal Infra Projects Pvt. Ltd. & Ors., 2025 SCC OnLine SC 1041

While the full text is not reproduced, the Delhi High Court quoted paragraphs emphasising:

  • Bank guarantees are the “backbone of commercial transactions”;
  • Courts must be “reluctant” to grant injunctions, except in cases of fraud or irretrievable injury;
  • The terms of the guarantee are crucial: where it is unequivocal and unconditional, the bank must pay “without demur or objection”.

These authorities collectively underpinned the Court’s refusal to treat appropriation of PBG as an “irretrievable harm” or as a ground in itself to entertain the writ petition.

2. Supreme Court and High Court on alternative remedy & Section 27

(a) Radha Krishan Industries v. State of H.P., 2021 SCC OnLine SC 334

The Court invoked the summary of principles at paragraph 27 (quoted in full in Trimula) concerning:

  • The general rule that writ courts ordinarily decline jurisdiction where an efficacious alternative remedy exists;
  • Recognised exceptions: enforcement of fundamental rights, violation of natural justice, lack of jurisdiction, or challenge to vires of legislation;
  • The “rule of exhaustion” as a matter of policy and discretion, not of lack of jurisdiction.

(b) Trimula Industries Limited v. Union of India, Ministry of Coal & Ors., 2024 SCC OnLine Del 3350

This Division Bench decision is pivotal. It concerned:

  • An almost identical context: commercial coal mine allotment under CM(SP) Act, CMDPA, and appropriation of PBG for failure to meet efficiency parameters;
  • A challenge to a second appropriation order; the first had been stayed earlier in writ proceedings;
  • The Single Judge directed the petitioner to avail the Section 27 remedy, and the Division Bench upheld that approach.

The Division Bench held:

“…When a right is created by a statute, which itself prescribes the remedy or procedure for enforcing the right or liability, resort must be had to that particular statutory remedy before invoking the discretionary remedy under Article 226… The principle laid down by the Supreme Court in paragraph 27.5 [of Radha Krishan] is attracted…”

Importantly:

  • The DB characterised disputes over non-disclosure of forest land and efficiency parameters as questions of fact fit for the Tribunal;
  • It noted that earlier ad-interim relief in a related writ does not preclude relegation to the statutory forum; and
  • It extended interim protection while directing the petitioner to approach the Tribunal.

Justice Amit Sharma expressly treated Trimula as binding and directly applicable to Vedanta’s case.

(c) Petitioner’s authorities on writ jurisdiction

Vedanta relied on several Supreme Court authorities to argue for maintainability despite alternative remedy:

These cases generally stress that:

  • Article 226 jurisdiction is plenary and not ousted by the mere existence of alternative remedies;
  • Alternative remedy is a matter of judicial discretion, not of competence.

The Court acknowledged this line of authority but held that, in light of the specific statutory scheme of Section 27 and the binding Division Bench ruling in Trimula, discretion should be exercised in favour of relegating Vedanta to the Tribunal.

(d) Joshi Technologies International Inc. v. Union of India, (2015) 7 SCC 728

Cited by the respondents, this case stresses that where a contract prescribes a particular dispute resolution mechanism (especially arbitration), writ courts normalement refuse to intervene in disputes that are primarily contractual in nature.

3. Contractual clauses & bank guarantee wording

CMDPA Clauses 6 and 10 (Performance Security and Efficiency Parameters)

Key provisions referred to:
  • Clause 6.2 — Events for appropriation of Performance Security (PBG), including failure to comply with Efficiency Parameters (Clause 6.2.1(d));
  • Clause 6.2.2 — Exception where the Appropriation Event occurs solely due to force majeure that could not be mitigated by good industry practice;
  • Clause 6.3 — Manner of appropriation; PBG may be appropriated in prescribed percentages for specific events; failure to top‑up may itself become a termination event;
  • Clause 10 — Obligation to comply with Efficiency Parameters (Milestones) within prescribed timelines (reinforced by Schedule D).

Bank Guarantee Terms

The PBG contained clear unconditional wording, including that:
  • The bank undertook to pay “without any demur, reservation, caveat, protest or recourse” upon first written demand;
  • The Nominated Authority’s demand would be final and binding as to amounts payable;
  • The bank waived any requirement for the Authority to first proceed against Vedanta.
These terms were central to the Court’s application of bank guarantee jurisprudence.

V. Legal Reasoning of the Court

1. Encashment of PBG and the “fraud / irretrievable injustice” standard

The Court first addressed the bank guarantee dimension. After surveying Himadri Chemicals, Standard Chartered Bank, and Jindal Steel, it reiterated that:

  • Performance security in the form of an unconditional PBG is an independent contract between bank and beneficiary;
  • Disputes about CMDPA performance — timelines, force majeure, interpretation of milestones — are irrelevant to the bank’s obligation to honour a valid invocation;
  • Court interference is permissible only if:
    • There is fraud of an egregious nature directly affecting the bank guarantee; or
    • Encashment would cause irretrievable injustice or special equities.

On the facts, the Court found:

  • Vedanta had voluntarily given a written undertaking on 12 August 2024 to operationalise the mine by 3 June 2025 in response to the 24th Scrutiny Committee’s recommendation.
  • That undertaking was not qualified as “under protest” and was not challenged through any legal process.
  • The issues Vedanta later invoked (boundary discrepancies, environmental issues, etc.) were already within its knowledge when it gave the undertaking.

On this basis, the Court held that Vedanta’s situation did not fit any of the exceptions (fraud, irretrievable injustice, special equities) which could justify an injunction against encashment of an unconditional PBG. This significantly weakened the case for invoking writ jurisdiction solely on the ground of PBG appropriation.

2. Alternative remedy and Section 27 CM(SP) Act

The second and decisive limb of the reasoning concerns maintainability under Article 226 in light of Section 27 CM(SP) Act, 2015, which provides:

“(1) Any dispute … arising out of any issue connected with the Act shall be adjudicated by the Tribunal… (4) On and from the commencement of the Act, no court or other authority, except the Supreme Court and a High Court, shall have, or be entitled to exercise, any jurisdiction, powers or authority, in relation to matters connected with the Act.”

Key points in the Court’s analysis:

  1. Existence and functionality of the Tribunal
    • Vedanta argued the Tribunal at Talcher was not fully functional and not suited for this type of dispute.
    • The ASG produced an order dated 9 May 2025 to show that the Tribunal was, in fact, functioning.
    • The Court accepted that the statutory forum is available and operational.
  2. Nature of the dispute The Court characterised Vedanta’s grievances as involving:
    • Interpretation of CMDPA terms (e.g., computation of MS‑3 due date under Schedule D);
    • Factual controversies (boundary coordinates, forest area reclassification, elephant corridors, timing and nature of environmental and forest clearances, effect of COVID‑19 and Model Code of Conduct);
    • Application of force majeure under Clause 25 and Clause 6.2.2 (whether delay was solely due to force majeure, and whether Vedanta exercised “good industry practice”).

    All these are disputed questions of fact and contract interpretation, squarely within the remit of the Tribunal under Section 27.

  3. Binding effect of Trimula Industries
    • The Single Judge acknowledged that prior Supreme Court cases (e.g., Whirlpool) leave Article 226 jurisdiction intact despite alternative remedies.
    • But given a directly on-point Division Bench decision in Trimula regarding Section 27 and PBG appropriations, this Single Judge was bound to follow that course: relegate the petitioner to the Tribunal, with limited interim relief.
  4. Reconciliation with Section 27(4)
    • Section 27(4) saves the jurisdiction of High Courts and the Supreme Court.
    • The Court treated this as preserving competence, not mandating exercise of jurisdiction in every case; discretion is still guided by the alternative remedy doctrine and binding precedent.

3. Treatment of petitioner’s specific arguments

Although the Court declined to decide merits, its treatment of some arguments is implicit:

(a) Miscalculation of MS‑3 due date

Vedanta argued that:

  • As per Schedule D, MS‑2’s completion time is 6 months from allocation, and MS‑3’s 18 months from completion of MS‑2;
  • Therefore, MS‑3 due date should be calculated as 3 March 2023, not 3 September 2022; EC obtained on 23 January 2023 would then be timely;
  • Further, SCN‑I having been waived by the 18th Scrutiny Committee, the “delay” in MS‑2 stood condoned.

The respondents countered that:

  • Radhikapur (West) is a fully explored mine, so MS‑1 was inapplicable and nothing remained for Vedanta to do under MS‑2 because the mining plan and mine closure plan had already been approved in 2011 (as per Annexure to the Vesting Order);
  • Hence, the 18 months for MS‑3 ran from 3 March 2021 (vesting date) itself.

The Court expressly noted that such contentions go to interpretation of the CMDPA and its schedules, and to the effect of Scrutiny Committee recommendations — matters best adjudicated by the Tribunal.

(b) Force majeure and COVID‑19, environmental and forest hurdles

Vedanta relied on Clause 25 (force majeure) and Clause 6.2.2 to argue that:

  • Boundary coordinate confusion, need for DGPS survey (ORSAC data), change in forest classification, elephant corridor issues, requirement for fresh EC due to MoEF&CC’s stance, COVID‑19 lockdowns, and Model Code of Conduct cumulatively constituted force majeure events;
  • These events were beyond its control and could not be mitigated by “good industry practice”, so PBG should not have been appropriated at all.

The Court did not opine on whether these factors amount to force majeure. Instead, it treated this as a substantive contractual defence which the Tribunal should examine.

(c) Non-functional Tribunal and scope of its jurisdiction

Vedanta tried to argue that:

  • The Tribunal is not properly functional and is primarily designed to handle land acquisition and compensation issues under the Coal Bearing Areas Act, not CMDPA disputes; and
  • Hence, the alternative remedy is neither efficacious nor appropriate.

The Court rejected this implicitly by:

  • Noting that the Tribunal had in fact passed orders (order dated 9 May 2025 produced by the ASG);
  • Relying on the explicit wording of Section 27 extending the Tribunal’s jurisdiction to “any dispute… arising out of any issue connected with the Act”, which plainly covers CMDPA/efficiency parameter disputes.

(d) Reliance on other cases and on JSW Cement interim order

Vedanta invoked a coordinate bench order in M/S JSW Cement Limited v. Union of India & Ors. (W.P.(C) 8484/2025), where the Court had stayed appropriation of a PBG in a similar context.

Justice Amit Sharma distinguished that situation in light of the binding Division Bench decision in Trimula and clarified that the latter, being a reasoned precedent on Section 27, must govern.

VI. Impact and Significance

1. Consolidation of the “Section 27 Tribunal first” rule

This judgment, read with Trimula Industries, effectively establishes a strong judicial policy for the Delhi High Court that:

  • Where a dispute arises from CMDPAs, efficiency parameters, PBG appropriations, or other issues “connected with” the CM(SP) Act, Section 27 is the primary route;
  • Article 226 will generally not be exercised to resolve such disputes, especially where:
    • The Tribunal is functional; and
    • Disputed questions of fact and contract interpretation are involved.
  • High Court intervention would be exceptional, confined to classic alternative remedy exceptions (e.g., jurisdictional error, patent violation of natural justice, constitutional issues) — which were absent here.

2. Reinforcement of strict approach to PBG encashment

By applying the bank guarantee jurisprudence to a public–private CMDPA context, the Court underscores that:

  • PBGs in coal mine auctions will be treated like any other commercial bank guarantees; their encashment will not be lightly restrained;
  • Even large sums (here, Rs. 29+ crores) or allegations of miscalculation in timelines and force majeure do not by themselves amount to “irretrievable injustice”;
  • Commercial bidders in coal auctions must be prepared for real and immediate financial consequences for failure to meet milestones, subject to whatever relief they can secure from the Tribunal.

3. Practical guidance for future bidders and allottees

This ruling carries important practical lessons:
  • Plan for Tribunal litigation, not writ petitions: Allottees should expect that challenges to PBG appropriation, milestone calculations, or zero-date disputes will need to be pursued before the Section 27 Tribunal.
  • Exercise caution when giving undertakings: As seen here, an unconditional undertaking to operationalise the mine by a specific date (given to avoid immediate penalty) can later operate strongly against the allottee.
  • Force majeure claims are fact‑intensive: The Court has signalled that such claims (COVID‑19, environmental constraints, land classification changes) are prima facie matters for the Tribunal, not for quick resolution in writ.
  • EC/FC and boundary disputes are not short-cuts to stay PBG encashment: Even complex regulatory hurdles — EC transfers vs. fresh grant, FC Stage‑I/II conditions, elephant corridors, DGPS–ORSAC issues — will need to be properly pleaded, proved, and adjudicated; they do not automatically justify writ interference.

4. Institutional strengthening of the Section 27 Tribunal

By repeatedly directing parties (Vedanta here, Trimula earlier) to the Tribunal, the High Court implicitly:

  • Affirms the Tribunal’s jurisdiction and competence to handle sophisticated commercial–regulatory disputes linked to coal mine allocation; and
  • Encourages the development of a specialised body of decisions on CMDPA, milestones, and PBG disputes at the Tribunal level, subject to supervisory and appellate review by High Courts and the Supreme Court.

VII. Complex Concepts Simplified

1. CMDPA and “Efficiency Parameters” (Milestones)

A Coal Mine Development and Production Agreement (CMDPA) is the primary contract between the Central Government (through the Nominated Authority) and the successful bidder for a coal mine. It:

  • Specifies the obligations for developing and operating the mine;
  • Contains a timeline in the form of Efficiency Parameters (Schedule D) — milestone-based deadlines for steps like:
    • Approval of mining plan (MS‑2);
    • Obtaining EC and FC (MS‑3);
    • Land acquisition & rehabilitation (MS‑4);
    • Commencement of production/operationalisation (MS‑5).
  • Links failure to meet these milestones with financial consequences — principally partial or full appropriation of the Performance Bank Guarantee.

2. Performance Bank Guarantee (PBG)

A Performance Bank Guarantee is a promise by a bank that if the bidder fails to perform its obligations (e.g., meet milestones), the government can demand a specified sum from the bank. Key features:

  • It is a separate contract between bank and beneficiary (government), independent of the CMDPA;
  • Often expressly states that payment is “without demur” and on first demand;
  • Disputes between government and bidder do not prevent the bank from paying when properly invoked;
  • Court interference is rare and limited to fraud or irretrievable injustice.

3. Section 27 Tribunal

Section 27 of the CM(SP) Act gives a specialised Tribunal (constituted under the Coal Bearing Areas (Acquisition and Development) Act, 1957) the power to decide:

  • Any dispute arising from actions of the Central Government, Nominated Authority, Commissioner of Payment, or Designated Custodian;
  • Any dispute between successful/allottees and prior allottees;
  • Any issue connected with the CM(SP) Act — which now clearly includes CMDPA milestone and PBG appropriation disputes.

High Courts and the Supreme Court retain oversight and constitutional jurisdiction, but as this judgment illustrates, they increasingly expect parties to use the Tribunal first.

4. Force majeure in CMDPA context

Force majeure refers to extraordinary events beyond a party’s control (natural disasters, war, pandemics, regulatory actions) that make performance impossible or impracticable. Under the CMDPA:

  • Clause 25 defines force majeure events and sets conditions, including taking reasonable steps to mitigate;
  • Clause 6.2.2 specifically says PBG will not be appropriated when an Appropriation Event occurs solely due to force majeure that could not be mitigated through “good industry practice”.

Whether a particular delay is excusable under this clause requires a detailed factual inquiry — which is why the Court directed Vedanta to the Tribunal.

5. EC and FC (Stage‑I & Stage‑II)

Two crucial environmental approvals in coal mining are:

  • Environment Clearance (EC) under the EIA Notification, 2006 — based on environmental impact assessment and public hearing;
  • Forest Clearance (FC) under the Forest (Conservation) Act, 1980:
    • Stage‑I (In‑principle) approval, usually with detailed conditions (e.g., compensatory afforestation, wildlife management plan, elephant conflict mitigation);
    • Stage‑II (Final) approval, granted once conditions are met.

In Vedanta’s case, regulatory complications arose over:

  • Whether EC granted to the prior allottee could be transferred or had lapsed;
  • Need for fresh ToR and EC application; and
  • Compliance with FC conditions (e.g., compensatory afforestation, elephant habitat issues).

VIII. Conclusion: Key Takeaways

The decision in Vedanta Ltd v. Nominated Authority, Ministry of Coal does not pronounce on whether Vedanta was right or wrong in claiming extensions, force majeure, or miscalculated milestones. Its enduring significance lies elsewhere.

In doctrinal terms, the judgment:

  • Strengthens the centrality of the Section 27 Tribunal for disputes “connected with” the CM(SP) Act, especially those involving CMDPA milestones and PBG appropriations;
  • Reaffirms strict limits on judicial interference with unconditional bank guarantees, even when the sums are large and underlying contractual disputes are complex;
  • Clarifies that factual and contractual controversies — boundary discrepancies, EC/FC timelines, elephant corridors, COVID‑19 or election‑related delays — are for the specialised Tribunal to resolve, not for summary determination in writ jurisdiction.

In practical terms, the message to miners and commercial bidders is clear:

  • CMDPA obligations and Efficiency Parameters are real, enforceable, and backed by meaningful financial risk via PBGs;
  • When disputes arise, the primary venue will be the Talcher Tribunal under Section 27, and bidders should structure their dispute strategy accordingly;
  • Writ petitions may still be available, but largely in exceptional situations engaging constitutional or jurisdictional defects — not as a first‑resort remedy against every PBG appropriation or milestone dispute.

By aligning coal mine disputes with the general law on alternative remedies and bank guarantees, this judgment furthers predictability and discipline in India’s commercial coal mining framework, while ensuring that a specialised forum — the Section 27 Tribunal — develops and applies the intricate mix of contractual, regulatory, and environmental norms that such projects inevitably involve.
