The National Green Tribunal (NGT) on Thursday asked the Delhi University’s Hindu College to stop construction work of a hostel and plant 100 trees on its premises against the ten trees it had cut. The Tribunal has posted the matter for July 27. A Bench -- headed by NGT chairperson Justice Swatanter Kumar -- ordered, “You (college) must first plant 100 trees against 10 trees you have felled for construction work. Submit a report and show us the proof after which you can start the work.”
