A class action suit against Gandhi was filed by Sikhs for justice (SFJ), a US-based human rights group, along with victims of the November 1984 under Alien Tort Claims Act (ATCA) and Torture Victim Protection Act (TVPA).
SFJ legal counsel Gurpatwant S Pannun said federal court Judge Brian M Cogan's order further directs the hospital and security staff to give summons and complaint to Gandhi personally in the hospital.
66-year-old Gandhi, who had undergone a surgery in the US for an undisclosed ailment on August 5, 2011, had flown there for a check-up in February and again on September two last year.
