New Delhi: A day after the Delhi government suspended physical classes in the schools of the capital owing to the increasing levels of pollution, the Supreme Court on Friday clarified that it did not ask the government to shut schools. It only asked the reasons behind the change in the stance of the government, the Chief Justice of India-led bench said as it continued hearing the case. The Apex Court on Thursday gave the Delhi government a 24-hour deadline to place some concrete steps against pollution. As the government listed the decisions it took, including that of the suspension of physical classes, the Supreme Court gave go-ahead to the Delhi government for the construction works of hospitals.
