"Put up for order on November 30," Special CBI Judge O P Saini said after hearing the arguments in which Special Public Prosecutor U U Lalit said the opinion of a handwriting expert was necessary to ascertain the signatures on some documents which were filed in the court along with the charge sheet.
Lalit said during the probe, statements of some prosecution witnesses were recorded but they were unable to identify as to who had put their signatures on the documents.
The agency had moved an application seeking permission to take specimen signatures of three top executives of Reliance Anil Dhirubhai Ambani Group (RADAG) -- Gautam Doshi, Surendra Pipara and Hari Nair who are facing trial in the case.
Lalit told the court that signatures of these three accused are there on some important documents but witnesses have not been able to identify the same.
Opposing the CBI's plea, senior counsel Mukul Rohatgi, who appeared for Doshi and Pipara, said the agency's application is "vague" and it is meant to "harass and create prejudice" against the accused.
"It is just a vague and bald application. It is meant only to harass and create prejudice to the accused and the CBI is not interested in fair play," Rohatgi said.
Doshi, Pipara and Nair, along with former Telecom Minister A Raja and others, are facing trial for their alleged role in the 2G case. Reliance Telecom Ltd is also an accused in the case.
