NEW DELHI: Endorsing strict implementation of lockdown and social distancing norms to prevent spread of Covid-19 pandemic, the Supreme Court on Wednesday said that the war against the Corona virus caused disease, which forced the government to extend lockdown till May 3, could not be won without people's cooperation.Dismissing two PILs seeking action against police for ruthlessly enforcing lockdown through brutal use of physical force in several states, a bench of Justices N V Ramana, S K Kaul and B R Gavai said concerned High Court and statutory human rights bodies have taken cognisance of instances of alleged use of excessive force by police and that there would be no reason for the SC to take up the issue through fresh PILs.However, the bench said, "police authorities are working hard to implement the lockdown order and without cooperation of the citizens, they shall not be successful. Citizens must follow the norms of social distancing and stay indoors for the benefit of their family and community." Solicitor general Tushar Mehta told the court that relevant guidelines have been issued to state governments and police for effective enforcement of lockdown to prevent spread of the virus by using minimum force against those violating lockdown direction.A Guwahati-based advocate, Amit Goyal, had requested the SC to restrain police from beating up members of public who ventured out during the lockdown period. He said lack of clear guidelines on movement of public during lockdown has resulted in uncertainty and chaos in certain areas where essential items are in short supply. He said the police appeared to be ignorant about exemption granted to certain categories of professionals, who too got beaten up by uniformed personnel. He sought a uniform guideline for movement of public during lockdown.A Delhi-based advocate Vishal Tiwari too had filed a PIL seeking directions to the Centre and the states to register criminal cases against errant police officials for unleashing brutalities on public on many occasions during the lockdown in Rajasthan, Haryana, U.P, Gujarat and Telangana After hearing the advocate petitioners and the solicitor general, the bench said, "such instances have already been taken cognizance of by concerned High Courts and the Human Right Commissions. In the aforesaid circumstances, it will not be appropriate to pass a general order or directions, as appropriate authorities have already taken cognizance of the same". Dismissing the petitions, the bench told the petitioners that if they came across any specific instances of police excesses during lockdown period, they could approach concerned HCs or appropriate forum.
