"The party does not doubt his integrity. This precise issue has been raised by Dr Swamy in the apex court and is sub judice.
"Without waiting for the proceedings to be completed, it is highly objectionable and inappropriate for Dr Swamy or anyone else to pass premature judgement on the very same issue on which he is seeking relief", party spokesman Abhishek Singhvi told PTI.
Singhvi said the "mischievous attempt" to create a rift between different constitutional functionaries is highly regrettable and ought not to be repeated.
His reaction came after Swamy submitted to the Supreme Court a Finance Ministry document which said the Telecom Ministry could have gone in for auction of 2G spectrum licenses had the then Finance Minister P Chidambaram insisted on this.
The March 25, 2011 office memorandum by the Finance Ministry headed by Pranab Mukherjee sent to the Prime Minister''s Office(PMO) also suggested that Chidambaram and the jailed former Telecom Minister A Raja had jointly determined the price for the 2G spectrum in 2008.
Swamy presented the documents before the apex court bench of Justice G S Singhvi and Justice A K Ganguly which is hearing his application seeking a Central Bureau of Investigation (CBI) probe into Chidambaram's alleged role in deciding the price of 2G spectrum allocation.
