The 2G spectrum scam involved the illegal allocation of telecom licenses by former telecom minister A. Raja, leading to significant financial loss estimated at Rs 1.76 lakh crore. This case highlights the misconduct within government institutions, regulatory bodies, and telecom companies that exploited the first-come, first-served policy instead of auctioning the spectrum at fair market value. The Supreme Court quashed all licenses granted during this period and initiated proceedings against several implicated individuals and firms.
