Bhushan said he is collecting documents regarding the coal block allocation, which the Comptroller and Auditor General (CAG) has found fault with, and preparing a detailed complaint.
"Sometime next week, I will be filing it in the Supreme Court. Like in the 2G case, I will be demanding cancellation of the allocation and an independent probe by a Special Investigation Team," he told PTI.
He said an independent probe is necessary and the CBI cannot be entrusted with the investigations as the agency is controlled by the government.
The lawyer had earlier filed a complaint with Supreme Court in the 2G spectrum case seeking cancellation of the licences awarded to several private parties.
