Government cannot unilaterally impose retrospective one-time spectrum charges absent express contractual or statutory authorization.

The Petitioners, cellular mobile service operators, challenged a 2012 decision by the Union of India (Respondent) to impose a "one-time spectrum charge" (OTSC).

This charge was applied retrospectively from July 2008 to December 2012 for spectrum held above 6.2 MHz.

The Petitioners had originally operated under the 1994 Telecom Policy (fixed fees) and migrated to the National Telecom Policy 1999 (NTP-99), which used a "revenue-share" model.

Between 2001 and 2005, through amended license agreements and Unified Access Services (UAS) licenses, the Respondent allocated additional spectrum in exchange for increased percentage points of Adjusted Gross Revenue (AGR).

In late 2012, based on internal committee reports and a 2010 TRAI recommendation, the Respondent issued demand notices for OTSC, claiming spectrum was previously allocated "virtually free of charge".

1. Whether the Respondent—Union of India—possesses the statutory or contractual power to unilaterally impose a one-time spectrum charge retrospectively.

2. Whether the terms of the license agreements (contracts) executed under Section 4 of the Telegraph Act, 1885, permit the imposition of such additional consideration after the grant of license.

Section 4 of the Telegraph Act, 1885, which grants the Central Government the exclusive privilege to delegate telegraph rights through licenses on "such conditions and in consideration of such payments as it thinks fit".

Union of India v. Association of Unified Telecom Service Providers of India, establishing that a license under Section 4 is a "contract" between the licensor and licensee.

Delhi Development Authority v. Joint Action Committee, holding that a "definite price" is an essential element of a binding agreement and terms cannot be altered unilaterally without a specific provision in the contract or law.

Doctrine of Legitimate Expectation and the principle that executive orders cannot be applied retrospectively unless the statute expressly permits it, as seen in BSNL v. Tata Communications Ltd.

The Court reasoned that since a telecom license is a contract, the Respondent is bound by its terms and cannot invoke the "public interest" clause (Clause 13(ii)/5.1) to generate revenue beyond the agreed-upon consideration.

The Respondent failed to prove that any of the three contingencies for modification (public interest, security, or proper conduct of telegraphs) were met, especially since the objectives of NTP-99 focused on "affordable service" and "rural teledensity" rather than "revenue maximization".

The Court found that additional spectrum was never "free," as Petitioners had already paid consideration via increased percentage points of revenue share (AGR) as stipulated in the 2001-2005 amendments.

The retrospective imposition of OTSC in 2012 for the period starting in 2008 was deemed an illegitimate executive action lacking statutory backing, violating the principles of "consistency, transparency, and predictability" in administrative law.

The Court respectfully disagreed with the Madras High Court’s Aircel decision, noting that revenue maximization does not automatically equate to public interest.

The Court quashed and set aside the Impugned Decisions dated 08.11.2012 and 28.12.2012, along with the consequential demand notices, and directed the Respondent to return any bank guarantees furnished by the Petitioners.
