The Bhopal-based interior designer Zahida, her assistant Saba Farooqui and two alleged shooters Shakib 'Danger' and Irfan were produced before the special CBI court of judicial magistrate Dr Shubhra Singh.
As soon as the proceedings began, the defence counsel of BJP MLA Dhruvnarayan Singh whose name also figured in the murder case, filed a petition saying the court was "misled" by CBI on the polygraph test conducted on him.
Referring to the petition, senior public prosecutor Hemant Shukla told reporters that "the special CBI court has neither accepted it nor rejected it".
When asked about the content of the petition filed by defence counsel Pradeep Gupta on the behalf of the legislator, Shukla said, "It was the proceeding matter and cannot be divulged as the court neither accepted nor rejected it".
Meanwhile, the court dismissed the petition filed by one of the Shakib's wife Noorjahan who alleged that CBI was "torturing" her husband in its custody.
On alleged sharp shooter Tabish Khan's denial that he made statement under section 164 of CrPc in connection with the murder of the 32-year-old activist, Shukla said, "It is the willingness of the accused...CBI cannot force him to make a statement".
Shehla was shot dead outside her residence at posh Koh-e-Fiza locality in Bhopal on 16 August last year.
