NEW DELHI: The Supreme Court on Thursday made it clear that CBI cannot evade periodic scrutiny of its probe into Coalgate, querying the agency's reluctance to file a status report and voicing doubts about the legal sanctity of coal block allocations.

The court's remarks on the central bureau of investigation's ongoing probe into massive irregularities in coal block allocations highlighted by the federal auditor came in the wake of one of the petitioners, NGO Common Cause, questioning efficacy of the investigations.
