These zonal councils, he underlined, are extremely important for dialogue, cooperation, coordination, and ‘policy synergy’.During the meeting, Shah, along with the chief ministers of Haryana, Punjab, Himachal Pradesh, J&K, Rajasthan and Delhi; LGs of J&K, Delhi and Ladakh; and the administrator of Chandigarh, observed two minutes silence as a tribute to the victims of Delhi car bomb blast and the recent explosion at Nowgam police station in J&K.Emphasising the continued need for all-out efforts to ensure speedy justice in crimes against women and children and also eradicate malnutrition and stunting, Shah called for speedy investigation in cases of sexual offences and rape under the Pocso Act, besides seeking an increase in the number of fast track special courts.
