Can a regulator appeal against its own order being corrected?

The electricity regulator fixed tariffs. The tribunal said: wrong. The regulator then appealed to the Supreme Court. The Court asked: who are you to appeal your own mistake?

For nearly a decade, the Orissa Electricity Regulatory Commission (OERC) set the prices at which GRIDCO—a state government company—sold bulk electricity to four distribution companies (DISCOMs). Every year, the DISCOMs argued the tariffs were unfair. Every year, the Appellate Tribunal for Electricity agreed, correcting the Commission's errors. And every year, the Commission itself appealed those corrections to the Supreme Court. The question that hung over all those appeals was deceptively simple: Can a quasi-judicial regulator appeal against a tribunal's correction of its own order?

When the regulator became the appellant

The case began with a routine regulatory exercise. Every financial year from 2006-07 to 2014-15, the OERC determined how much money GRIDCO needed to recover through tariffs—the Aggregate Revenue Requirement (ARR)—and the Bulk Supply Tariff (BST) that DISCOMs would pay. The Commission also fixed the Transmission Tariff (TT) and Retail Supply Tariff (RST) that end-consumers would see on their bills.

The DISCOMs—Western Electricity Supply Company of Orissa Ltd. and others—challenged these orders before the Appellate Tribunal. Their argument was straightforward: the Commission had allowed GRIDCO to recover costs that should not have been passed through to consumers, and had excluded revenues that should have been counted. The Tribunal agreed on several points and sent the matters back to the Commission for correction.

Then the Commission itself appealed to the Supreme Court under Section 125 of the Electricity Act, 2003 (the provision allowing appeals from the Tribunal's orders on substantial questions of law). The Commission argued that the Tribunal had overstepped its jurisdiction and that its own tariff orders were correct.

The Supreme Court was unimpressed. "The Commission cannot be an aggrieved party entitled to prefer appeals against corrections of its own quasi-judicial orders," the bench of Justice Sanjay Kishan Kaul and Justice Abhay S. Oka observed. The only exception, the Court noted, would be where the Commission was challenging non-compliance with its own orders—a situation that did not arise here.

Why a regulator cannot be an aggrieved party

The Court's reasoning turned on the nature of the Commission's function. Under Section 62 of the Electricity Act (the provision for tariff determination), the Commission exercises a quasi-judicial power—it hears parties, considers evidence, and passes a reasoned order. When the Appellate Tribunal corrects that order under Section 111 (the appeal provision), it is performing a supervisory function. The Commission, having already discharged its adjudicatory role, has no independent stake in the outcome.

"If the Commission were allowed to appeal every correction of its order," the Court seemed to say, "it would become a party to the dispute rather than an arbiter." The regulator's role is to decide, not to defend its decisions against higher scrutiny.

The Court drew support from the principle established in DSR Steel (Private) Limited v. State of Rajasthan—that a quasi-judicial authority cannot be an aggrieved party when its order is set aside in appeal. The Commission's proper recourse, the Court held, was to assist the Tribunal and the Supreme Court with its expertise, not to litigate against the very parties it was meant to regulate.

The double-recovery trap that consumers would have paid for

Beyond the question of the Commission's locus (its legal standing to appeal), the Court addressed a substantive issue that would have hit every electricity consumer in Orissa: double recovery of loan principal.

GRIDCO had borrowed money to build transmission infrastructure. The principal amount of these loans was already being recovered through the BST that DISCOMs paid—and which consumers ultimately bore. But GRIDCO argued that because it had not recovered the full cost of power in earlier years, the principal amount of new loans taken to cover those shortfalls should also be passed through in tariffs.

The Court rejected this argument. "Where energy cost has already been passed through in BST in earlier years, the principal loan amount borrowed due to non-recovery of such costs cannot be allowed to pass through again in ARR/BST," the judgment held. To allow such double recovery, the Court said, would be to charge consumers twice for the same expense.

The ruling has immediate practical consequences. Every time a distribution company or bulk supplier seeks to recover loan principal in its tariff, regulators must check whether that same cost has already been recovered. If it has, the second claim must be disallowed.

When export revenue belongs to consumers

The Court also settled a recurring dispute about surplus power. GRIDCO, as a bulk supplier, sometimes had more power than its DISCOMs needed. It sold this surplus to other states or through power exchanges, earning what is called export or trading revenue.

GRIDCO argued that this revenue was its own—earned through its commercial acumen—and should not be deducted from the costs that consumers paid for. The Court disagreed. "When the entire power purchase cost of a bulk supplier is allowed as expenditure in ARR, revenue earned from export/trading of surplus power cannot be excluded from the supplier's revenue computation," the judgment stated.

The logic is simple: if consumers bear the cost of buying all the power, any revenue from selling surplus power must reduce the amount consumers pay. To hold otherwise would be to let the supplier keep a profit it never earned—a profit that belongs, in fairness, to the consumers who funded the power purchase in the first place.

Why DISCOMs can challenge bulk supply tariffs

One procedural point that the Court clarified will affect future tariff litigation. The Commission had argued that DISCOMs had no locus standi (legal standing) to challenge the BST—the price at which GRIDCO sold power to them—because the BST did not directly affect consumers. Only the RST, the Commission said, was a matter for DISCOMs to challenge.

The Court rejected this argument. "Distribution licensees have locus standi to challenge BST fixation orders as RST determination depends on BST determination," the bench held. If the BST is set too high, DISCOMs' costs increase, and either their margins shrink or the RST must rise. Either way, DISCOMs are directly affected and can be aggrieved parties.

The ruling ensures that distribution companies—the entities closest to consumers—have a voice in every layer of tariff determination, not just the final retail price.

The limits of Supreme Court interference

On most of the factual disputes—the correct treatment of advance against depreciation, the methodology for truing-up exercises (adjusting past tariffs to reflect actual costs), the allocation of transmission losses—the Court declined to interfere. "Courts under Section 125 will be slow to interfere with factual findings of expert bodies like the Commission and Appellate Tribunal," the judgment noted, "given their specialized composition and the statutory limitation to substantial questions of law."

This is a reminder that the Supreme Court's role in electricity tariff appeals is narrow. The Electricity Act creates a specialized regulatory architecture precisely because tariff determination requires technical expertise that generalist courts lack. The Court will correct errors of law, but it will not second-guess the Commission's or the Tribunal's judgment on matters of fact or tariff policy.

The one exception was the issue of advance against depreciation—a mechanism that allows utilities to recover a portion of asset cost before the asset is fully depreciated. On this narrow point, the Court restored the Commission's original order, finding that the Tribunal had misapplied the regulatory framework.

What this means for every electricity stakeholder

For regulators, the message is clear: once you pass a tariff order, you cannot appeal its correction. Your role ends when the order is signed. For utilities, the lesson is that loan principal cannot be recovered twice—no matter how creative the accounting. For consumers, the ruling ensures that surplus power revenue reduces their bills, not the supplier's profits.

THE PLAY: When challenging a tariff order before the Appellate Tribunal, ensure that the regulator's own appeal is met with a preliminary objection on locus—the regulator cannot be an aggrieved party against corrections of its own quasi-judicial order.

The Court dismissed most of the appeals, upheld the Tribunal's corrections, and sent a message that the regulatory architecture of the Electricity Act works as designed—when everyone stays in their lane. The question remains: will regulators now stay in theirs?
