The scathing observations by the court came during the hearing of a coalscam case pertaining to allocation of Rajhara North coal block in Jharkhand to accused firm Vini Iron and Steel Udyog Ltd (VISUL).
The court was infuriated after the counsel appearing for various accused, including former Jharkhand Chief Minister Madhu Koda, moved applications that the case records supplied to them by the CBI were "insufficient and illegible".
Responding to this, the IO said he was busy in a number of other cases and his senior officers were insisting that he complete the probe in those cases as well.
"This is a strange kind of submission made by the IO. When one charge sheet has already been filed in the court then it is the duty of the prosecution, duly supported by the investigating agency, to present and pursue the case in right earnest and it does not lie in the mouth of the IO to say that being busy in some other matter he could not devote time in the present case," the judge said.

During the hearing, which commenced at 10 am, the court directed the IO to supply all the necessary documents required by the defence counsel today itself and adjourned the matter for 2 pm.
As the hearing resumed at 2 pm, the judge himself saw the documents supplied to the defence counsel and found that some of the records were illegible or some portion was cut in the photocopies.
The court observed that its function is to conduct a free and fair trial and the role of prosecution is to assist in trial while the role of the investigating agency is to render help to the prosecution.
