The complaint had been filed by RTI activist Vivek Garg, accusing the Prime Minister and Maran of "unlawfully changing and diluting" the original Terms of References (ToRs) for vacation and reallocation of spectrum leading to the 2G scam.
Garg had earlier sent a complaint to the CBI and the anti-corruption branch of the Delhi government, before moving the court.
The court said: "It is clear that no other court except the special court of OP Saini, Special CBI Judge, Patiala House Court, can deal or try any matter related to 2G scam, and there is no dispute that the complaint pertains to the 2G scam."
