Swamy had sought prosecution of many in the Aircel-Maxis deal case.
The 2G spectrum case relates to the 2G spectrum licence allocations in 2007-08, which caused, according to a report by the Comptroller and Auditor General of India, a loss of Rs 1.76 lakh crore to the public exchequer.
The Aircel-Maxis deal refers to a series of allegations of kickbacks in the telecom sector, which was part of the wider 2G scam.
In 2011, former Aircel head C Sivasankaran complained to the CBI that he was being forced by then telecom minister Dayanidhi Maran to sell Aircel to the Malaysia-based Maxis Communications group owned by T Ananda Krishnan.
