New Delhi: A Delhi court on Saturday allowed CBI, which is yet to file its third supplementary chargesheet in the 2G scam, to quiz afresh the former Telecom Minister A Raja, former Telecom Secretary Siddhartha Behura and Reliance ADAG Group MD Gautam Doshi, in judicial custody.

Special CBI Judge O P Saini allowed the application of the agency that in the interest of the case, it required to interrogate key accused afresh during the on-going probe.

The court also trashed the vehement plea of defence lawyers that they were in dark as to why the agency wanted to interrogate the accused again.

"It is between the court and the prosecution. Accused has no right to be heard in this regard at this stage. The application (of CBI) is allowed," it said.

During the argument, a defence counsel raised the objection, saying "CBI must clarify as to why and in which regard, they are seeking permission for interrogation."

"We are in dark. Court is saying that argument on charges should begin but new things are coming in light now," the defence counsel said.

CBI has moved the plea seeking interrogation of Raja and others, who are in judicial custody, in connection with the case on Monday.

"Further investigation is being carried out and three accused persons namely A Raja, Siddharth Behura and Gautam Doshi are required to be examined in judicial custody in interest of the case," the application said.

CBI can file additional documents

Meanwhile, a Delhi court on Saturday rejected the objections of the accused and allowed CBI to place on record some additional documents and statements of witnesses, including some transcripts of conversations between corporate lobbyist Niira Radia and others, relating to 2G spectrum allocation scam.

The court said allowing CBI's plea would not cause "prejudice" to the accused as the progress of the case before it was at an initial stage.

"In view of the law and facts quoted above (in the order), it is clear that the prosecution may file additional documents and list of witnesses, subsequent to the filing of the chargesheets, if they are considered relevant by it, more so when the case is still at an initial stage and no prejudice is being caused to the accused."

"The applications filed by CBI are squarely covered by the law and, as such, deserve to be allowed and the same are accordingly allowed. The documents are ordered to be taken on record," Special CBI Judge O P Saini said.

CBI had filed four applications in April and July for filing some additional documents and statements of witnesses. The agency had also sought the court's permission to take these documents on record.

CBI prosecutor A K Singh had countered the submissions of the accused saying when the prosecution could conduct further probe, it could also file additional list of witnesses and documents, if it deemed it necessary. The accused had contended if these documents were filed with the chargesheets earlier, then the court might not have taken cognizance in the case. However, the court had rejected the contentions.

The agency had also sought to rely on an additional statement of Radia recorded by it on May 12 after filing of the first two chargesheets in the case.

It also sought the court's permission to submit a total of 28 additional documents and a list of 11 witnesses in support of its chargesheets filed on April 2 and April 25, 2011.

"It is prayed that the additional documents and the witnesses are relevant to the chargesheet and are relied upon by the prosecution and the same may be taken on record in the interest of justice," the CBI had said.

CBI has added 11 more prosecution witnesses to bolster its case against the high-profile accused, including former Telecom Minister A Raja and DMK MP Kanimozhi, in the scam.

The probe agency had filed 654 documents and a list of 125 witnesses with the first chargesheet while 135 documents and a list of 28 witnesses were filed along with the supplementary charge sheet.
