Chief Metropolitan Magistrate (CMM) Amit Bansal, who was scheduled to pass the order today, deferred it till tomorrow as it was yet to be finalised.
Dabas had moved the court seeking bail, saying there was no direct evidence against him and was falsely implicated in the case by the police. He had alleged that he had become a "victim of the system".
He was arrested on February 14 for allegedly trying to access Jaitley's call details. According to police, Dabas had used the official email ID of an Assistant Commissioner of Police to send a request to a mobile service provider for the call detail records of the BJP leader.
The police, on the other hand, had opposed his bail plea and had argued that offences of forgery may be made out against the four arrested accused including Dabas.

Besides Dabas, three private detectives -- Anurag, who is alleged to be the main conspirator, Neeraj and Nitish -- have been arrested and all of them are in judicial custody till March 20.
During the arguments held in-camera on Dabas' bail plea, the police had said that offences under sections 464 (making a false document), 468 (forgery for the purpose of cheating) and 471 (using as genuine a forged document) of the IPC may be made out against the accused in the case.
Countering the plea of the accused, the police had said that offences related to forgery under the IPC were non- bailable and Dabas should not be granted the relief.
