On November 20, 2025, the Supreme Court of India passed a landmark order in the T.N. Godavarman Thirumulpad vs. Union of India case, accepting recommendations of a Court-appointed Committee regarding the definition of Aravalli Hills and Ranges. The new definition adopted: 'Any landform located in the Aravalli districts, having an elevation of 100 metres or more from local relief' constitutes Aravalli Hills; two or more such hills within 500 metres of each other form the 'Aravalli Range'. The Court imposed an interim moratorium on new mining leases until a landscape-wide Management Plan for Sustainable Mining (MPSM) is prepared. It also accepted recommendations for prevention of illegal mining and permitting only sustainable extraction in Aravalli Hills and Ranges. The Aravalli mountain range — one of the oldest geological features of planet Earth — stretches approximately 692 km from Gujarat to Delhi, passing through Rajasthan (largest portion) and Haryana. Rajasthan's Aravalli belt covers districts including Sirohi, Udaipur, Rajsamand, Ajmer, Alwar, and Jhunjhunu and is crucial to groundwater recharge, biodiversity conservation, and protection from Thar Desert advancement. Note: The Supreme Court later (December 29, 2025) stayed this very order amid concerns it could weaken ecological protections.
Supreme Court's November 20 Order on Aravalli Hills: New Definition, Mining Moratorium, and Conservation Framework

The Court imposed an interim moratorium on new mining leases until a landscape-wide Management Plan for Sustainable Mining (MPSM) is prepared. It also accepted recommendations for prevention of illegal mining and permitting only sustainable extraction in Aravalli Hills and Ranges. The Aravalli mountain range — the world's oldest folded mountain range (~3,500 million years old) — stretches approximately 692 km from Gujarat to Delhi, passing through Rajasthan (largest portion) and Haryana. Rajasthan's Aravalli belt covers districts including Sirohi, Udaipur, Rajsamand, Ajmer, Alwar, and Jhunjhunu and is crucial to groundwater recharge, biodiversity conservation, and protection from Thar Desert advancement.

Mains angle
Q: Evaluate the Supreme Court's November 20, 2025 Aravalli order—its new definition, mining moratorium, and subsequent stay—and its implications for ecological protection in Rajasthan and Haryana.
Answer (50 words):
On November 20, 2025, the Supreme Court in the T.N. Godavarman case adopted a new Aravalli definition—landforms 100 metres above local relief in Aravalli districts, groups 500 metres apart forming the Range—and imposed an interim moratorium on new mining leases pending a Management Plan for Sustainable Mining; stayed December 29, 2025.

Frequently asked questions
What new definition of Aravalli Hills did the Supreme Court adopt in its November 20, 2025 order?
The Supreme Court accepted a Court-appointed Committee's definition: any landform in the Aravalli districts with an elevation of 100 metres or more from local relief constitutes an 'Aravalli Hill'. Two or more such hills within 500 metres of each other form an 'Aravalli Range'. This precise scientific definition replaced the earlier ambiguous geographical descriptions and has direct implications for forest protection and mining regulation.
What is the MPSM and why did the Supreme Court impose an interim moratorium on new mining leases in the Aravallis?
MPSM stands for Management Plan for Sustainable Mining — a comprehensive environmental framework that must be prepared before new mining leases can be granted in the Aravalli region. The Supreme Court imposed an interim moratorium on new mining leases until the MPSM is prepared, to prevent irreversible ecological damage to the Aravalli ecosystem while the regulatory framework is being finalised.
What is the geological significance of the Aravalli range?
The Aravallis are among the oldest geological features of planet Earth. They stretch 692 km from Gujarat in the south to Delhi in the north, with Rajasthan having the largest portion. Geologically they are Pre-Cambrian metamorphic rocks. The range acts as a critical watershed, feeding rivers such as the Banas, Luni, and Sabarmati.
In which Supreme Court case was the November 20, 2025 Aravalli order passed, and what was the significance of December 29, 2025?
The order was passed in the T.N. Godavarman Thirumulpad vs. Union of India case — the landmark forest conservation case that has been ongoing since 1995. On December 29, 2025, the Supreme Court stayed its own November 20 order amid ecological and procedural concerns, temporarily suspending the new definition and moratorium, which makes this a still-evolving legal matter relevant for RPSC current affairs.
Why is the Aravalli range of particular ecological importance for Rajasthan and the broader region?
The Aravallis serve as a natural barrier against the eastward spread of the Thar Desert, protecting the fertile plains of Haryana and Rajasthan. They are a critical recharge zone for groundwater, a habitat for biodiversity including leopards and migratory birds, and provide ecological services such as carbon sequestration. Unregulated mining threatens to accelerate desertification and groundwater depletion in an already water-stressed region.
