M/s Aravali Power Co. Pvt. Ltd. vs Vedprakash
Background
This batch of appeals arose from several National Green Tribunal (NGT) orders concerning thermal power plants' failure to properly dispose of and utilise fly ash, the ash residue from burning coal, as required by statutory notifications under the Environment (Protection) Act, 1986. Specifically, Civil Appeal Nos. 1692-1693 of 2020 was Aravali Power Company's challenge to an NGT order dismissing a review of an earlier direction requiring remedial action against the company for improper fly-ash disposal that allegedly harmed nearby agricultural land. While the batch of appeals was pending in the Supreme Court, the Union Ministry of Environment, Forest and Climate Change issued a fresh notification on 31 December 2021 superseding the older fly-ash notifications and prescribing new timelines (including specifically for "legacy ash" (previously accumulated, unutilised ash)) for compliance.
Decision Breakdown
The Supreme Court held that this new December 2021 notification fundamentally altered the regulatory basis on which the various NGT orders (which had been based on the older, superseded notifications and deadlines) had found the thermal power plants non-compliant and imposed environmental compensation. Since the very foundation of the NGT's findings had been overtaken by the new rules, the Court set aside all the impugned NGT orders across the entire batch of appeals, including the one concerning Aravali Power. It also directed the Ministry to review whether the new notification needs further modification to align with the Hazardous Waste Management Rules, 2016, and to ensure the notification's own monitoring, audit, and enforcement mechanisms are actually put in place within three months. The Court expressly clarified that this was not a ruling on the merits or validity of the new notification itself, leaving any party aggrieved by it free to challenge it separately.
Lesson Learnt
When the law or regulatory framework underlying a tribunal's order changes significantly while an appeal is pending, courts may set aside the earlier order as having lost its legal foundation, rather than deciding the original dispute on its old facts, but this is not the same as ruling that everyone is now off the hook, since the new rules and compliance obligations still apply going forward.
