The 2G spectrum case involved a $40 billion alleged scam during the UPA government in India from 2008 to 2009. Politicians like A. Raja and M.K. Kanimozhi, as well as bureaucrats like Siddharth Behura and R.K. Chandolia were accused of undercharging mobile companies for 2G licenses. This caused a major loss to the public exchequer. Activists and lawyers like Prashant Bhushan, Subramaniam Swamy and Vinod Rai pursued the case, resulting in the cancellation of 122 telecom licenses by the Supreme Court in 2012. Investigations are still ongoing around related issues like the Aircel-Maxis deal.
