any day after August 15.
The court had on July 19 allowed CBI's plea to make Anil and Tina Ambani prosecution witnesses in the case as their testimonies may throw light on alleged investment of over Rs 990 crore by his group companies in Swan Telecom, facing trial in the case along with its promoters Shahid Usman Balwa and Vinod Goenka.
It had said CBI's plea to summon Ambani, his wife and 11 others as prosecution witnesses was essential for arriving at a just decision in the case.
On July 25, the Supreme Court had refused to grant an urgent hearing on the plea of Reliance Telecom Ltd (RTL), an accused in the case, challenging the trial court's order summoning Anil and Tina as prosecution witnesses in the case.
The RTL's plea is being heard by the apex court's special bench comprising justices G S Singhvi and K S Radhakrishnan which is hearing all the matters pertaining to the 2G scam, and has been listed for August 21 for further arguments.
The trial court, while allowing the CBI's plea, had said testimonies of Anil and Tina Ambani are required to prove the facts "pertaining to incorporation of shell companies as some of the witnesses examined earlier have not been able to do so".
It had dismissed the contentions of the counsel for the accused that CBI's plea "suffers from the vice of delay", saying the process of examination of prosecution witnesses is still underway.
RADAG's company, RTL, is an accused in the case. Three top Reliance ADAG executives Gautam Doshi, Surendra Pipara and Hari Nair are also facing trial in the case.
CBI has alleged that RTL used Swan Telecom, an ineligible firm, as its front company to get 2G licences and radio waves.
