The definition had effectively shrunk the more than 650-km ancient range to a few hills. It militated against a more than two-decade-old jurisprudence, in which the Court had drawn on its expansive interpretation of forests in the Godavarman (1996) case, to nudge the often mining-friendly state governments in the Aravalli region — Rajasthan, Haryana and Delhi — to protect the hills. The Court’s demand for a definition of the Aravallis was, of course, grounded in a need to address a regulatory deficit. Last year, it found that an inconsistent definition of the range was the major reason for the persistence of illegal quarrying. However, the SC’s decision to accept the criteria proposed by a panel constituted by the environment ministry — only landforms at an elevation of 100 m or more should be considered as part of the mountain system — invited controversy. Fears that this height filter would aggravate the ecological insecurity of the Aravallis triggered protests in Rajasthan. A series of reports in this newspaper pointed out that the new definition would diminish the ecological services of the Aravallis. On Monday, a three-judge bench led by CJI Surya Kant took suo motu notice of the range of voices, including this newspaper’s, that urged the Court to review its order. The decision to put the 100-m rule in abeyance is a much-needed course correction.A committee of experts will now be formed to re-examine how to map the Aravallis. Its mandate includes addressing a major concern flagged by the Forest Survey of India (FSI). The agency had underlined that less than 10 per cent of the Aravalli hills made the 100-m cut. The SC’s own amicus curiae and the CEC had concurred with the FSI: They had warned that the definition could open vast stretches of the Aravallis to mining.AdvertisementFor starters, the committee would do well to go back to the central message of SC verdicts — hills, ridges, plateaus and forests in the Aravallis function as one ecosystem. In 2010, this respect for the range’s ecological integrity was the main reason for the Court’s rejection of the 100-m threshold proposed by the then Congress government in Rajasthan. Eight years later, a two-judge bench recognised how even small hills in the Aravallis were an anti-pollution shield for the Indo-Gangetic region. Now, with a vast swathe of the region blanketed in toxic smog, the salience of the Court’s latest intervention cannot be overstated. It must continue to hold out against attempts to diminish the nearly two-billion-year-old mountain system.
