In the case of M.C. Mehta v. Union of India (2026), the Supreme Court of India formally disposed of one of its oldest pending matters—a writ petition filed in 1984 regarding the preservation of the Taj Mahal—to transition the litigation into a more structured and manageable framework.
The following is a summary of the judgment and the Court’s new directions:
Case Evolution and Background
The litigation originated 42 years ago when environmental activist M.C. Mehta sought the Court’s intervention to stop the yellowing and blackening of the Taj Mahal’s white marble caused by industrial emissions, vehicular traffic, and the Mathura Refinery. Over decades, this “continuing mandamus” expanded into a broad environmental cause encompassing heritage conservation, industrial regulation in the Taj Trapezium Zone (TTZ), and the protection of ecological balance.
Reason for Formal Closure
The Court noted that the proceedings had expanded far beyond the original 1984 petition, resulting in a “record as it now stands” containing more than 150 pending interlocutory applications (IAs) on heterogeneous issues. To ensure administrative manageability and timely consideration of diverse concerns, the Court determined that these issues should be categorized and handled through new, specialized proceedings rather than under the umbrella of a single 40-year-old petition.
The Four New Suo Moto Cases
While formally closing the original writ petition, the Court directed the Registry to register four new Suo Moto Writ Petitions (Civil) to address the surviving concerns in the Taj Trapezium Zone:
- Vision Document for the Taj Trapezium Zone.
- Protection of Trees and Green Cover in the TTZ.
- Regulation of Industries in the TTZ.
- Protection and Management of Water Bodies and Sewage in the TTZ.
Management of Pending Applications
The Court laid down a strict procedure for clearing the backlog of existing applications:
- Infructuous Applications: Advocates-on-Record (AORs) must inform the Registry by May 15, 2026, if their pending applications have become infructuous. Failure to do so will result in a presumption that the application is no longer active.
- Active Applications: If an application remains active, the AOR must specify which of the four new suo moto cases it falls under and provide a reasoned note explaining why it hasn’t been covered by previous court orders.
- Transfer of Issues: Applications requiring further judicial consideration will be transferred to the respective new suo moto petitions.
Continued Binding Effect of Past Orders
The Court explicitly clarified that the formal closure of the 1984 petition does not efface the binding character of the numerous orders and directions issued by the Court over the last four decades. Those directions remain operative and final unless modified in future proceedings.
Guidelines for Tree Cutting/Relocation
To streamline future requests for infrastructure or development projects, the Court directed that any petition seeking permission to cut or relocate trees in the TTZ must include a tabulated chart. This chart must detail the project proponent, the number and type of trees affected, and specific plans for compensatory afforestation.
