As per case facts, this Writ Petition is the second round of legal action concerning the safety and environmental aspects of the Tehri Dam. Petitioners sought directions for further safety ... tests, alleged non-compliance with Environmental Clearance conditions, and raised concerns about rehabilitation. Earlier, an Expert Group recommended abandoning the project, but it was revived with foreign assistance. Environmental clearance was granted conditionally, requiring environmental measures to proceed simultaneously with construction. The question arose whether to allow the project to proceed despite allegations of non-compliance with environmental and rehabilitation conditions and safety concerns, especially given previous court rulings and expert opinions. Finally, the Court, in its majority opinion, upheld the government's decision regarding safety, transferring the matter to the High Court of Uttaranchal for monitoring compliance with conditions, explicitly stating that impoundment would commence only after full compliance with rehabilitation and environmental measures. A dissenting opinion, however, called for more stringent monitoring and mandatory 3-D Non-Linear Analysis before impoundment.
