PHILADELPHIA (AP) — Several businesses and residents have filed suit in state court in Pennsylvania seeking to overturn Philadelphia’s renewed indoor mask mandate scheduled to be enforced beginning Monday amid a surge in COVID-19 infections. Philadelphia earlier this week became the first major U.S. city to reinstate its indoor mask mandate after reporting a sharp increase in coronavirus infections. Attorney Thomas W. King III said the city’s emergency order went against Centers for Disease Control and Prevention recommendations and “imposed a renegade standard." The Philadelphia mayor’s office declined comment but said courts have ruled that the city “has both the legal authority and requisite flexibility" to take steps to control COVID-19 spread.
