A bench headed by NGT chairperson Swatanter Kumar said, "We are sure nothing has been done. There is no regulatory mechanism.
"We want barriers points to be fixed, speed cameras to be installed by next date of hearing and challans (of vehicles) be done and show how are you (Assam) trying to protect animals from entering the most vulnerable area of the 20.5 km road passing through the national park."
"Fixing barriers, cameras and challaning vehicles doesn't need a 30-page report," the bench remarked.
It also said "the suggestions made (by the state) can hardly be considered in the absence of MoEF which is a necessary party."
