Raja, who earlier had demanded to summon Chidambaram to court as a witness, suddenly retracted from his demand and claimed that the home minister should not be investigated as the further questioning would delay the 2G spectrum case.
Earlier on Monday, arguing to defend his candidate, Raja's lawyer threw the challenge for the present home minister by claiming, "Let Chidambaram accept or deny whether he gave the advice in presence of PM or not."
"There was no difference of opinion between then telecommunication (Raja) and the then finance minister (Chidambaram)," claimed the lawyer adding, "My job is done if Mr Chidambaram comes to court."
However, the sudden U-turn by Raja and his lawyer in the court shocked many. Meanwhile, the investigative agency, Central Bureau of Investigation (CBI) also overruled the central government and claimed that no one can direct them as they are an independent body.
