The complaints, filed separately with the two agencies, by the NGO, Telecom Watchdog, sought a thorough probe and registration of FIR under the Prevention of Corruption Act against Sibal for allegedly abusing his official position to benefit a private party at the cost of exchequer.
The NGO said it was filing the complaints as the Supreme Court on July 11 had refused to entertain an identical plea on the ground that the issue was not related to the 2G spectrum and gave liberty to the petitioner to avail other legal remedies to get the matter investigated.
The two companies named in the complaints are Reliance Communication Ltd (RCL) and Reliance Telecom Ltd (RTL).
The plea in the apex court was made by another NGO, Centre for Public Interest Litigation (CPIL).
When the NGO, CPIL filed an affidavit in the apex court in the 2G matter, Sibal reacted strongly saying PILs should not be used to settle personal scores and dismissed the charges against him as "malicious, motivated and defamatory".
