Sounding a note of caution, about the adverse impact of underwater sand mining, Chief Justice Madan B. Lokur asked the advocate-general to seriously reconsider its policy on allowing it. The Chief Justice was hearing a batch of writ petitions on sand mining along with Justice P.V. Sanjay Kumar. The High Court had put a ban on sand mining across the state with effect from April 1 and the state government had filed an appeal, urging the court to lift the ban.
