CHENNAI: The Madras High Court has directed the State government and the Greater Chennai Corporation to amend within six months, the rules regulating the erection of hoardings and banners. The court gave the directive when a PIL from ‘Traffic’ K R Ramaswamy, an activist, came up on Friday. Reiterating its earlier orders, the bench said the rules should make it mandatory to display whether permission had been granted and if so, the date, number and other particulars, to enable the authorities concerned to take stringent action against those who erect hoardings and banners, unauthorisedly.
