Order of the National Green Tribunal in the matter of Pravesh Vs Ministry of Environment, Forest and Climate Change & Others dated 31/01/2019. NGT in an order had directed that no stone crushers be permitted to operate unless they obtain consent from the State Pollution Control Board, proper no objection certificate from the concerned authorities and have the Environmental Clearance (EC) from the competent authority. This application seeks ‘modification’ of the order to the effect that the stone crushers should be allowed to set up without EC.

The Tribunal while dismissing the application said that "unless EC is held to be required, the mushrooming of stone crushers even without any carrying capacity will continue which is not in consistent with precautionary principle for the protection of environment nor with the principle of sustainable development".
