The National Green Tribunal has refused to recall its order directing Afcons Infrastructure Limited and Larsen Toubro Limited to pay compensation of Rs 1 crore each for unscientific muck dumping in Arzi nallah at the Pakal Dul Hydroelectric Project in Kishtwar district of Jammu and Kashmir.A bench headed by NGT chairperson Justice A K Goel said once the applicants caused damage and violated environmental norms, they cannot escape liability.Subsequent clearance of waste cannot be a ground for waiving the compensation for damage already caused and violation already committed.
