Following its November acceptance of a controversial 100-metre elevation definition for the Aravalli hills, the Supreme Court has taken suo motu cognizance amid backlash, listing the matter for hearing on December 29. The move addresses concerns that the definition could expose over 90% of the hills to mining and construction, threatening ecology.
A three-judge bench led by Chief Justice Surya Kant, with Justices J K Maheshwari and A G Masih, will hear the case on December 29, after the Supreme Court initiated suo motu proceedings on December 27.
The controversy stems from the court's November 20 adoption of the 100-metre elevation criterion, recommended by a union environment ministry panel. This follows an earlier Forest Survey of India benchmark using a 3-degree slope, which the Central Empowered Committee (CEC) urged retaining in letters dated October 14 and November 7. The CEC also opposed renewing 164 mining leases in Rajasthan, many below 100 metres.
Amicus curiae K Parameshwar warned that the new definition would fragment the hills' continuity, endangering ecology. The Centre argued mining bans in core areas (except critical minerals) and sustainable practices would mitigate risks. Reports indicate over 90% of hills could lose protection, impacting Delhi-NCR air quality and water recharge.
In May 2024, the court allowed states to process Aravalli lease applications but required approval. This hearing balances conservation with mining interests amid ongoing protests and expert cautions.
