With the public spotlight on Mr Jagdish Tytler and Mr Sajjan Kumar, the role of Mr Kamal Nath, minister of road transport and highways, in the 1984 carnage is treated as a forgotten, closed chapter. However, the ghosts of 1984 are back to haunt Mr Nath. On a visit to the USA, the minister found himself summoned by a US federal district court in a civil case filed under the Alien Torts Claims Act, where the petitioners have sought compensatory and punitive damages for several allegations including crimes against humanity, degrading treatment and wrongful killing. Mr Nath, PTI reports, needs to respond within 21 days otherwise the court will give a default judgement on the matter.
