Suo Motu Cognizance Current Affairs for UPSC

The Supreme Court has invoked its extraordinary powers under Article 142 to crack down on rampant illegal sand mining inside the tri-state National Chambal Gharial Sanctuary, pulling up Rajasthan, Madhya Pradesh and Uttar Pradesh for "casual and indolent" inaction after two forest guards were killed in 2026. This in-depth explainer covers the Chambal sanctuary's unique ecology, the critically endangered gharial, India's sand-mining laws (MMDR Act, Sustainable Sand Mining Guidelines), the Deepak Kumar verdict, denotification controversies, and the constitutional principles of environmental governance — everything a UPSC aspirant needs in one place. Why in News The Supreme Court of India is hearing a suo motu case on large-scale illegal sand mining inside and around the National Chambal (Gharial) Sanctuary, a riverine protected area shared by Rajasthan, Madhya Pradesh and Uttar Pradesh. In a series of strongly worded orders through April and May 2026, the Court has rebuked the three state governments for administrative apathy, linked their inaction to the killing of frontline forest staff, and invoked Article 142 of the Constitution to issue sweeping enforcement directions. The case has brought national attention to sand mining as an environmental and rule-of-law crisis, and to the survival of the critically endangered gharial, whose last major wild stronghold is the Chambal.
