Justice P P Bhatt issued notice to CBI asking it to respond by April 21.
The petition was moved by former BJP MP from Junagadh, Solanki, seeking discharge in the murder case.
Solanki, currently out on bail, had challenged the order of the special CBI court which had rejected his discharge plea saying that evidence against him was sufficient for trial.
Solanki, who is facing trial for murder and criminal conspiracy, had claimed that the case against him was politically motivated.
