Much to the dismay of the owners of 5 industrial estates located in Naroda, Odhav and Narol areas in Gujarat, their writ petition, seeking permission to restart production was turned down by the Gujarat High Court judges on September 19. The division bench consisting of Acting Chief Justice R A Mehta and Justice H L Gokhale have stated that unless the units, which polluted the Kharicut canal with their efflucuts, falfil all norms of the Gujarat Pollution Control Board (GPCB), they cannot start their machines. The GPCB will also have to certify that the units have installed treatment plants and check the effluent samples before submitting a report to the court.
