Hearing the coal blocks allocation scam case in a packed courtroom, the bench said "suppression" of the fact that CBI has shared its probe report with the government is "not ordinary".
A bench headed by Justice R M Lodha observed that there was a "very disturbing feature" in the affidavit filed on April 26 by CBI Director Ranjit Sinha and the agency must be restored to its independent position.
The apex court said that sharing of information with the government about the probe into the scam has "shaken the entire process" and CBI need not take instructions from "political masters" on their probe.
