A five-member bench headed by NGT Chairperson Justice Swatanter Kumar issued a notice to Gujarat government and sought its reply by September 26.
The order came on a petition filed by Haryana-based agriculturist Virender Singh Choudhary who alleged the state has granted contracts permitting removal of sand upto a depth of 10 meters from river beds as against the three meter or water level depth recommended by the apex court.
The petition alleged since Gujarat government granted the contracts despite being aware of the apex court and the Tribunal's orders, it is "complicit in the violation of the judgment and the recommendations".
