Special CBI Judge O P Saini, who was scheduled to pass an order on the plea, posted it for August 17 after the counsel appearing on behalf of Swamy said that he would advance some arguments in the matter.
The lawyer told the court that Swamy was not in Delhi while the counsel, who was to argue on the plea, was unwell.
He had also alleged that examination of witnesses of the CBI is "incomplete" as they have not discussed the meetings which took place regarding the allocation of 2G spectrum during Raja's tenure as the Telecom Minister.
He had said that Raja's statement to the JPC speaks about various meetings which took place regarding allocation and pricing of spectrum.
