The CBI, in its reply, said its investigation into the case is independent and not inspired by Swamy's complaint.
It said the agency has collected necessary documents and recorded the statements of the witnesses during the probe and its investigation covers part of Swamy''s complaint as far as the Prevention of Corruption Act is concerned.
The Janata Party Chief had during the last hearing told the court that he should be associated in the case as he is willing to assist the CBI in a "formal way".
Swamy had said that although the CBI is probing the matter and has filed the charge sheet, his private complaint has wider ambit in some aspects.
"The scope of my application (private complaint) overlaps with the CBI case but in some cases its ambit is wider than that of the CBI's FIR," Swamy had said following which the court had asked the CBI to file its reply.
In his private complaint, Swamy had made a three-fold prayer which included that his complaint be taken cognisance of and Raja be summoned to take the case to its logical conclusion.
As per the second prayer, Swamy wanted the court to appoint him "as a deemed public prosecutor under the provisions of the Prevention of Corruption Act." Swamy also wanted the court''s directions to agencies like CBI and Enforcement Directorate to assist him in conducting prosecution and in further investigation into the scam.
He had also raised the national security aspect in the case, saying that Swam Telecom and Unitech Wireless, against whom the CBI had filed charge sheet in the 2G case, had sold their major shares to two foreign companies Etisalat DB and Telenor, which is "a major threat" to national security.
"The first two licensees, Swan Telecom and Unitech Wireless, soon after sold their controlling shares to Etisalat DB and Telenor respectively. The national security risk from these companies are highlighted by the Union Home Ministry as their connections go right into Pakistan," Swamy had alleged.
