M/S Sai Baba Sales Pvt. Ltd. v. Union of India
Background
A real-estate developer in Pimpri Chinchwad, Maharashtra, began a housing project below the size threshold that required a formal Environmental Clearance (EC). When the project was later expanded beyond that threshold, regulatory responsibility for granting the EC shifted between different authorities due to a series of changing central government notifications. The developer obtained an EC from the local municipal corporation under the rules in force at that time. A local resident later challenged this before the National Green Tribunal (NGT), arguing the EC was invalid because, under the original 2006 rules, only the state-level environmental authority (not the municipal corporation) could grant it. The NGT ruled that while further construction needed a fresh, valid EC, the buildings already constructed could be protected and were not required to be demolished. Both the developer and the original complainant appealed to the Supreme Court: the developer wanting to complete the fourth building, the complainant wanting the whole project penalized.
Decision Breakdown
The Supreme Court upheld the NGT's approach of protecting the already-built structures. It found that the developer had followed the regulatory regime that was validly in force at each stage of the project, had obtained EC from the authority that was competent at that time, and had made substantial investments in good-faith reliance on that approval. Applying the "Doctrine of Legitimate Expectation," the Court held that a developer cannot be expected to anticipate later changes to environmental rules (especially changes triggered by subsequent litigation) and cannot be forced to approach an authority that was not even empowered at the relevant time. The Court allowed internal completion work on the partly-built fourth building (already 40 of 64 flats sold) but made clear that any further new construction beyond the sanctioned buildings would require a fresh environmental clearance under the currently applicable rules.
Lesson Learnt
If a citizen or business follows the government's own rules and procedures as they validly stood at the time, and acts in good faith reliance on an approval granted under those rules, the law will generally protect what was already built even if the regulatory regime is later changed or invalidated, though this protection does not extend to future, not-yet-undertaken construction.
