1. Heading of the Judgment

Coal India Ltd. & Ors. vs. M/s Rahul Industries & Ors. with Transferred Cases
Citation: 2025 INSC 1103, Civil Appeal No. 11793 of 2025 (Arising from SLP (C) No. 21888 of 2012)
Court: Supreme Court of India
Bench: Justice J.B. Pardiwala and Justice R. Mahadevan
Date: September 12, 2025

2. Related Laws and Constitutional Provisions

The judgment extensively discusses and interprets the following legal frameworks:

• Article 14 of the Constitution of India: Right to Equality. The challenge was on the grounds of arbitrariness, unreasonableness, and hostile discrimination due to differential pricing.

• Article 39(b) of the Constitution of India: A Directive Principle of State Policy mandating that the ownership and control of material resources of the community should be distributed to subserve the "common good".

• The Essential Commodities Act, 1955: The Act under which coal was declared an essential commodity until it was de-listed in December 2006.

• The Colliery Control Order, 2000 (CCO, 2000): This order replaced the CCO, 1945 and was crucial as it deregulated the pricing of coal, transferring the power to fix coal prices from the Central Government to Coal India Ltd. (CIL) and its subsidiaries.

• The Coal Mines (Nationalisation) Act, 1972 & 1973: These acts were cited to emphasize that nationalized coal companies are not mere profit-making entities but are an extended arm of the welfare state with constitutional obligations.

3. Basic Judgment Details

• Parties:
  Appellants: Coal India Ltd. (CIL) and its subsidiaries (public sector undertakings).
  Respondents: M/s Rahul Industries and other private companies manufacturing smokeless fuel (part of the non-core sector).

• Subject Matter: Challenge to the validity of the Interim Coal Policy dated December 15, 2006, notified by CIL, which increased the price of coal for linked consumers of the non-core sector by 20% over the price notified in June 2004.

• Origin: The Calcutta High Court, vide its judgment dated April 4, 2012, had upheld the decision of a Single Judge which declared the Interim Policy invalid and ordered a refund of the 20% extra amount collected, with interest.

• Supreme Court's Decision: The Supreme Court allowed the appeal filed by Coal India Ltd., set aside the High Court's judgment, held the Interim Coal Policy to be valid, and consequently dismissed the respondents' claim for a refund.

4. Explanation of the Judgment

A. Factual Background and Context

The dispute has its roots in the history of coal distribution in India. Post-nationalization, coal was distributed through a "linkage" system where specific consumers were tied to specific mines. Consumers were classified into:

• Core Sector: Vital industries like power, steel, cement, fertilizers, etc., constituting over 90% of coal consumption. Any price increase here would have a cascading effect on the entire economy and common man.

• Non-Core Sector: Industries like smokeless fuel manufacturers, glass, etc., with minimal consumption.

In 2003-04, an e-auction system was introduced for the non-core sector to make distribution more transparent and curb black marketing. However, in the landmark case of Ashoka Smokeless Coal India (P) Ltd. v. Union of India, (2007) 2 SCC 640, the Supreme Court struck down the e-auction system. The Court held that as a state entity, CIL's primary goal could not be profit maximization; it had a constitutional duty under Article 39(b) to ensure equitable distribution and "common good". The e-auction, by creating variable and high prices, was arbitrary and violated Articles 14 and 39(b). The Court directed the formation of an expert committee to evolve a new viable policy.

In the interim period between the scrapping of the e-auction (Dec. 1, 2006) and the formulation of the New Coal Distribution Policy (Oct. 2007), CIL notified the Interim Coal Policy on December 15, 2006. This policy introduced dual pricing:

• Linked Core Sector: Continued to pay the old notified price (2004 price).

• Linked Non-Core Sector: Had to pay the old price plus a 20% premium.

• Non-linked Non-Core Sector: Had to pay an even higher price (old price + 30%).

The respondents (non-core, linked industries) challenged this 20% hike.

B. The Supreme Court's Analysis and Reasoning

The Supreme Court's analysis is a masterclass in judicial restraint in economic policy matters and the application of constitutional principles to pricing mechanisms.

1. Authority of CIL to Notify the Interim Policy:
The Court held that CIL did have the authority to notify the interim prices. It clarified that the direction in Ashoka Smokeless to form an expert committee was primarily for evolving a new supply and distribution policy. Crucially, the Colliery Control Order, 2000 (CCO, 2000) had already deregulated pricing and empowered coal companies (CIL and its subsidiaries) to fix coal prices. The Supreme Court cannot strip a company of a statutory power through a judicial order. Therefore, CIL was competent to fix interim prices.

2. Validity of the 20% Price Increase under Article 14:
This was the core issue. The respondents argued that charging linked non-core consumers 20% more than linked core consumers was discriminatory and violated Article 14. The Court rejected this argument, upholding the principle of reasonable classification established in Pallavi Refractories v. Singareni Collieries Co. Ltd., (2005) 2 SCC 227.

• Rational Nexus Test: The Court applied the "rational nexus" test (not the stricter "proportionality" test) as this was a case of classificatory arbitrariness (different treatment for different classes) rather than non-classificatory arbitrariness (same treatment for all).

• Objective of the Classification: The objective of the 20% hike was not mere profiteering. CIL argued, and the Court accepted, that it was to mitigate a 23.84% increase in its operational costs and to ensure the financial sustainability of its mining operations, which was essential for maintaining an adequate supply of coal in the market.

• Basis for Classification: The classification between core and non-core sectors was held to be rational and based on intelligible differentia:
  Impact on Public: A price hike for the core sector (90%+ consumers) would drastically increase the price of essential goods like electricity, cement, and steel, harming the common man. A hike for the small non-core sector would have a negligible impact on the public.
  Volume of Consumption: The core sector's massive consumption justified stable, lower prices to prevent economic disruption.
  "Common Good": The Court held that ensuring the financial health of CIL to maintain coal supply is itself a objective that subserves the "common good" under Article 39(b). The policy struck a balance between protecting the vast majority of consumers (core sector) and ensuring the producer (CIL) could operate sustainably.

3. Refund and the Doctrine of Unjust Enrichment:
Since the Court upheld the policy, the question of refund became moot. However, the Court provided a crucial alternative finding: even if the policy was invalid, it would not have ordered a refund.

• The Court distinguished this case from others (like Eastern Coalfields Ltd. v. Tetulia Coke Plant (P) Ltd., (2011) 14 SCC 624) where refund for e-auction excesses was ordered. In those cases, the amount was paid under a specific court order.

• Here, the 20% was paid in the normal course of business. The Court held that the burden of proof was on the respondents (the industries) to show that they had not passed on this additional 20% cost to their own consumers.

• Relying on Mafatlal Industries Ltd. v. Union of India, (1997) 5 SCC 536, the Court emphasized the doctrine of unjust enrichment. If the respondents had passed on the cost, granting them a refund would be a "windfall gain" unjustly enriching them at the expense of public money. The respondents failed to provide complete and irrefutable evidence (like full sets of audited accounts and sales bills) to prove they had absorbed the cost themselves.

• The Court concluded that in such a scenario, it is better for the state (CIL) to retain the money for public purposes rather than refund it to someone who did not ultimately bear the burden.

5. Supreme Court's Directions and Conclusion

• The appeal filed by Coal India Ltd. was allowed.

• The impugned judgment and order of the Calcutta High Court dated April 4, 2012, were set aside.

• The Interim Coal Policy dated December 15, 2006, was held to be valid.

• The respondents' claim for a refund of the 20% additional amount was dismissed.

• All pending transferred cases were disposed of in terms of this judgment.

In-Depth Analysis: 

This judgment reinforces the principle of judicial restraint in economic policy. The Court firmly stated that it is not its function to evaluate the wisdom of economic policies or to act as a super-administrator. Its role is limited to checking if the policy is based on a rational basis, legal authority, and conforms to constitutional morality (non-arbitrariness, fairness). The Court deferred to the expertise of the executive and CIL in making intricate economic choices necessary to balance consumer interests with the operational sustainability of a critical national resource. It established that reasonable profit for a state-owned company, when aimed at ensuring supply and subserving the "common good," is not anathema to the Constitution. The ruling also underscores the critical importance of the "unjust enrichment" doctrine in claims against the state, placing a heavy evidential burden on the claimant.
