Special CBI Judge O.P. Saini said: "The order will be pronounced after 2.30 p.m."
The CBI had named Kanimozhi, daughter of DMK chief M. Karunanidhi, and Sharad Kumar as co-conspirators in its April 25 supplementary charge sheet after it traced an illegal money trail of Rs.214 crore in the scam.
Kanimozhi, clad in an orange salwar-kurta, looked calm as she entered the Patiala House Court complex accompanied by her husband Aravindan.
Earlier in the day, when the special judge said the order would "take some time and come after 1 p.m.", Kanimozhi and Kumar looked relieved.
The 2G spectrum scam relates to irregularities in the allocation of airwaves to telecom companies that caused huge losses to the exchequer.
DMK MP and former communications minister A. Raja is already in jail in connection with the case.
Present in the courtroom Friday were former telecom secretary Siddharth Behura, Swan Telecom promoter Shahid Balwa, Raja's aide R.K. Chandolia, Vinod Goenka of Swan Telecom and Sanjay Chandra of Unitech.
Two officials of ADAG, Gautam Doshi and Hari Nair, who were also named in the charge sheet, were present in the courtroom.
Cineyug Film's Karim Morani was not present as he got exemption from personal appearance due to his ill health, while Surendra Pipara of Reliance, who is in judicial custody, was not presented in the court as he is undergoing treatment for a heart problem at the All India Institute of Medical Sciences (AIIMS).
Kalaignar TV channel had earlier stated that the Rs.214 crore it got was a loan and paid back with interest.
