Nainital: The Uttarakhand government and disaster management department on Wednesday filed an affidavit in the high court (HC) arguing that it is wrong to claim that they have not paid heed to the guidelines of the national disaster management policy of 2009 or that they acted callously which resulted in deaths of more than 200 people in the Rishianga flash floods in February. The 2009 policy states that it is essential to establish and modernise the early warning systems for all types of disasters. It adds that the nodal agencies responsible for surveillance shall identify technological gaps and plan for their upgrade in a time-bound manner.
