CBI spokesperson Dharini Mishra said the agency will study the orders of the court and decide on future course of action.
Agency sources, meanwhile, manintained that they had sent a team to record the statement of the witness based in the United States of America but his statements were not found to have any evidential value.
They said the witness had given them three more names who had claimed to have the information of Tytler's alleged role in the anti-Sikh riots which shook the city after the assasination of the then Prime Minister Indira Gandhi on October 31, 1984 by her Sikh bodyguards.
Asked about the future course of action by the agency, they said it would depend on the directive issued by the court and CBI is ready to probe again if the orders are for examination of only two-three witnesses.
CBI had filed closure report in the case saying the probe has made it clear that Tytler was not present on November 1, 1984 at Gurudwara Pulbangash in North Delhi where three people were killed during the riots.
Additional Sessions Judge Anuradha Shukla Bhardwaj today set aside the order of a magisterial court which accepted CBI's closure report.
