The Commonwealth Games basketball and squash courts, being built in Siri forest area in south Delhi, should be relocated to another site as it involved large-scale cutting of full-grown trees, amicus curiae Harish Salve said in his fresh plea before the Supreme Court. The application, which is scheduled to be heard by the Forest Bench comprising Chief Justice K G Balakrishnan and Justices Arijit Pasayat and S H Kapadia on Friday, said already 836 trees, each over 100-years-old, were cut to make way for the 30,000 sq metre concrete courts for the games. To complete the project, it would require cutting 100-odd more trees from the forest area, which is the lone lung space for south Delhi, the application filed through advocate A D N Rao said.
