In a statement here today, Singh said that the complaint against Gandhi had been lodged with clearly mala fide intentions.
"It defies logic to complain against someone who was nowhere near the government at the time of the riots," Singh said referring to Sonia.
In its lawsuit filed against Gandhi, members of US rights group Sikhs for Justice are seeking damages against the Congress President for her role in shielding and protecting Sajjan Kumar, Jagdish Tytler and other party leaders accused of leading attacks on members of the Sikh community following former Prime Minister Indira Gandhi's assassination in 1984.
Singh said it was highly condemnable that SFJ members had resorted to such tactics for cheap publicity at a time when Gandhi was in the USA for health reasons.
"This is just an act of cowardice which no Sikh can support or approve of," Singh said.
