Both. Each case shows a distilled summary — case type, key holding, and lesson learnt — and links to the full judgment as a PDF for when you need the complete text for research or citation.

Yes. Use Advanced Filters to narrow results by decision date and by practice area — including Constitutional Law, Criminal Law, Service & Administrative Law, Family Law, Civil Property & Inheritance, and Labour & Industrial Law.

BSES Rajdhani Power Ltd. vs Delhi Electricity Regulatory Commission

Civil Appeal · Not availableDecided 18 Oct 2022

Civil Appeal No. 4324 of 2015

Background

BSES Rajdhani Power Ltd. and BSES Yamuna Power Ltd., two Delhi electricity distribution companies (Discoms), challenged findings of the Appellate Tribunal for Electricity (APTEL), which had upheld several disallowances made by the Delhi Electricity Regulatory Commission (DERC) in its "truing up" (post-facto reconciliation) tariff orders for FY 2008-09 and 2009-10 and its Aggregate Revenue Requirement determination for FY 2011-12. The disputed issues included DERC's changed methodology for computing AT&C (Aggregate Technical and Commercial) losses and depreciation, disallowance of certain employee salary costs (FR/SR structure), disallowance of interest on Consumer Security Deposits still held by a government-owned holding company (DPCL) rather than transferred to the Discoms, disallowance of Fringe Benefit Tax, and the treatment of electricity theft/unauthorized-use ("enforcement") sales for loss calculation purposes.

Decision Breakdown

The Supreme Court held that a tariff order issued under Section 64 of the Electricity Act, 2003 is quasi-judicial and binding, and that the "truing up" exercise — meant only to reconcile actual expenses against earlier projections — cannot be used by the regulator to retrospectively rewrite the basic methodology or principles it originally used to determine tariff; this would amount to "changing the rules of the game after it has begun," which the law does not permit. Applying this principle, the Court set aside DERC's revised approach on AT&C loss computation, depreciation, and the disallowed FR/SR employee salaries and Fringe Benefit Tax, since each had improperly departed from the methodology fixed in the original tariff orders. On the Consumer Security Deposit issue, the Court held the Discoms were entitled to recover interest they were bearing on deposits never actually transferred to them by the government holding company, rejecting DERC's "double benefit" concern as misconceived. On enforcement (theft) sales, the Court held that where the law deems a certain quantity of electricity to have been "sold" (per DERC's own assessment formula), that legal fiction must be followed to its logical conclusion for loss-calculation purposes, even where a Lok Adalat settlement later reduced the monetary recovery. The appeals were allowed and the DERC/APTEL findings on these issues were set aside, with parties bearing their own costs.

Lesson Learnt

A quasi-judicial regulator that fixes tariff based on a stated methodology cannot later use a routine "truing up" or reconciliation exercise to retroactively change that methodology to the regulated entity's disadvantage — regulatory certainty requires that the rules governing a tariff period stay fixed once set, absent a proper amendment process.
