Judge Anupam Srivastava reserved the order after hearing the arguments by defence lawyer Pradeep Gupta and CBI's senior prosecutor Atul Kumar.
The accused had filed the pleas in December.
Advocate Gupta had argued that the trial was underway for over a year and would go on for long, so the accused be given bail. But prosecution argued that final arguments were yet to take place and the bail applications could be considered afterwards.
