Section 8 consumer associations qualify as “aggrieved persons” with locus standi to challenge electricity tariff orders.

The Appellant, Damodar Valley Power Consumers’ Association (DVPCA), an association of high-voltage consumers incorporated as a Section 8 company, challenged various tariff orders passed by the Central Electricity Regulatory Commission (CERC) and the West Bengal Electricity Regulatory Commission (WBERC) regarding projects operated by the Damodar Valley Corporation (DVC).

During final disposal in March 2025, Respondent No. 2 (DVC) filed applications seeking dismissal of the appeals, contending that DVPCA is a separate juristic entity that does not consume electricity itself and thus is not a "person aggrieved" under Section 111 of the Electricity Act, 2003.

In response, DVPCA sought to implead one of its members, M/s Maithan Alloys Ltd., as a co-appellant as a matter of abundant caution.

The Respondents argued that such impleadment at a belated stage could not cure an inherent jurisdictional defect or revive a time-barred cause of action.

1. Whether the Appellant Association qualifies as a "person aggrieved" under Section 111(1) of the Electricity Act, 2003, having the locus standi to appeal tariff orders.

2. Whether the Respondent is precluded from challenging the Appellant's locus standi based on the doctrine of "issue estoppel".

3. Whether a new party (M/s Maithan Alloys Ltd.) can be impleaded as an appellant at the final hearing stage and whether such impleadment relates back to the date of the original filing under Section 21 of the Limitation Act, 1963.

The Tribunal applied Section 111(1) of the Electricity Act, 2003, which allows "any person aggrieved" to prefer an appeal.

It read this alongside Section 2(49), defining "person" to include associations or bodies of individuals, and Section 2(15), defining "consumer".

The Tribunal relied on the doctrine of "issue estoppel" as elucidated in Raptakos Brett & Co. Ltd. v. Ganesh Property, which prevents a party from re-litigating an issue decided in previous proceedings between the same parties.

It further applied Order 1 Rule 10 of the Code of Civil Procedure (CPC) for the addition of parties and the proviso to Section 21(1) of the Limitation Act, 1963, regarding the retrospective effect of impleadment done in "good faith".

The Tribunal observed that Section 111(1) uses the broad term "person aggrieved" rather than "consumer," and the Appellant’s Memorandum of Association explicitly includes safeguarding consumer interests and opposing adverse electricity legislation.

Since tariff hikes directly impact the Appellant’s members (high-voltage consumers), the Association suffers a derivative injury sufficient to satisfy the "aggrieved" criteria.

The Tribunal distinguished Surat Citizens’ Council Trust, noting that DVPCA’s constitutional objects are specifically tied to electricity supply, unlike the trust in that case.

Regarding locus standi, the Tribunal found that DVC had failed to object to DVPCA's standing in multiple other appeals (e.g., Appeal No. 862/2023) where DVPCA was granted leave to appeal; thus, DVC was barred by "issue estoppel" from raising the objection at the final stage.

Finally, the Tribunal allowed the impleadment of Maithan Alloys Ltd., ruling that the omission to join it earlier was a "good faith" mistake based on the Appellant's prior successful litigation history, thereby allowing the impleadment to relate back to the original institution dates under Section 21 of the Limitation Act.

The applications filed by DVC (IA Nos. 726 of 2025, etc.) seeking dismissal were dismissed as devoid of merit.

The applications for impleadment (IA Nos. 804 of 2025, etc.) were allowed, with the Tribunal directing that the impleadment of M/s Maithan Alloys Ltd. relates back to the original filing date of the appeals.

The Appellant was directed to file an amended memo of parties within two weeks.
