Introduction


The recent Supreme Court judgment in Nabha Power Limited & Anr. vs. Punjab State Power Corporation Limited & Anr. offers a comprehensive analysis of how Cabinet decisions, press releases, and notifications interact with legally binding agreements, particularly under the Mega Power Policy and Customs Act. This case arose due to disputes over when certain changes in the Mega Power Policy took legal effect and how these changes impacted fiscal benefits granted to mega power projects.


Background of the Case


The dispute began when Nabha Power Limited, a subsidiary formed to develop a power project in Punjab, contested that the fiscal benefits tied to its “mega power project” status were affected by modifications announced in the government’s Mega Power Policy on 1st October 2009. Nabha argued that the Cabinet decision and subsequent press release on that date constituted a “change in law” under the Power Purchase Agreement (PPA), entitling them to certain benefits. However, Punjab State Power Corporation (PSPCL) disagreed, stating that the actual change in law occurred only upon the issuance of the official customs notification on 11th December 2009.


Key Issues and Constitutional Provisions


The Court considered the following main issues:

  1. What constitutes “law” under the Power Purchase Agreement? Clause 1.1 of the PPA defines “law” to include various statutes, rules, notifications, and orders by governmental bodies.

  2. Does a Cabinet decision, announced via press release, qualify as “law”? Nabha Power contended that the press release should be binding, while PSPCL argued that legal effect requires formal publication, as mandated by the Customs Act.

  3. When did the “change in law” effectively take place? The Court examined whether the 1st October 2009 press release itself altered the legal regime or whether the change occurred only after subsequent notifications.

Hon’ble Justice K.V. Viswanathan highlighted:

“Certainty is the hallmark of law. It is an essential attribute...and an integral component of the rule of law.”

This principle underscored the need for clarity in determining when legal changes affecting contractual obligations occur.


Analysis of Change in Law


Under the Customs Act, notifications and amendments must be officially published to be legally binding. The Court examined the 2009 press release, which communicated the Cabinet’s decision to modify the Mega Power Policy by relaxing some conditions, such as inter-state sale requirements. Nabha Power claimed they relied on this press release to factor fiscal benefits into their bid. However, the Court noted that this release was conditional and preliminary, requiring further action to give it legal effect.

Justice Viswanathan stated:

“The press release on 1st October 2009...was at best the announcement of a proposal approved by the Cabinet.”

The Court reasoned that only the official notification issued on 11th December 2009, which amended the customs duty exemptions for mega power projects, qualified as a change in law. Until that notification, the legal framework set by the Customs Notification of 2002 and the Mega Power Policy of 2006 continued to apply.


Interpretation of “Law” under the Power Purchase Agreement


The Court applied a detailed interpretation of Clause 1.1 in the PPA, which defines law in broad terms but does not explicitly include Cabinet press releases. It emphasised that “law” must be understood to mean “a command with force,” typically requiring a formal enactment. The ruling cited Babu Verghese vs. Bar Council of Kerala, emphasising that “if something is to be done in a particular manner, it must be done in that manner or not at all.”

The Court concluded:

“A press release does not fulfil the meaning of the word ‘order’...it is a proposal subject to fulfilment of certain conditions.”

This position reinforced the interpretation that informal announcements lack the force necessary to constitute “law” within contractual frameworks.


Implications

This judgment provides vital clarity on contractual obligations within public-private partnerships in the power sector. By establishing that policy changes affecting tariffs and fiscal benefits require formal publication to become binding, the Court sets a standard that ensures predictability in large-scale project investments.


The implications are particularly significant for entities relying on government incentives. Developers and power corporations now have a clear directive: only formal, gazetted notifications or similar publications can alter contractual obligations. This limits risks associated with fluctuating government policy announcements.


The Court’s decision also clarifies the responsibilities of bidders under the PPA’s clauses, reinforcing the expectation that they independently verify legal frameworks before bidding. This expectation strengthens the autonomy and accountability of private-sector participants in regulated sectors.


Conclusion


The judgment in Nabha Power Limited vs. Punjab State Power Corporation Limited is a milestone in defining what constitutes binding law within contractual obligations under government-regulated sectors. By reaffirming the importance of formal enactments, it underscores the balance between certainty in contractual relations and flexibility in state policy initiatives.

In this ruling, Hon’ble Justice Viswanathan encapsulated the Court’s stance:

“Certainty in law assures that changes impacting contractual obligations are introduced with transparency and predictability.”

This decision thus becomes a crucial point of reference for legal professionals and corporations involved in large infrastructure and power projects, reinforcing the necessity of formal publication for government decisions affecting fiscal or contractual matters.
