Justice Rajesh Dayal Khare reserved judgement on the petition of the Noida-based couple, whose petition was filed on May 15, two days after they were ticked off by the Supreme Court for adopting "a wrong procedure" by approaching it directly without first having moved the High Court.
The Talwars have challenged a CBI court order on May 4 whereby their request for summoning and recording statements of 14 witnesses, including top IPS officer Arun Kumar who is at present the ADG (Law and Order) of Uttar Pradesh and was a Joint Director of the CBI during the probe, was turned down.
The high-profile case was handed over to CBI after a recommendation to the effect by the then Uttar Pradesh Chief Minister, in the wake of outcry against alleged shoddy investigation by the police.
A closure report was filed by the CBI in December, 2010, wherein Rajesh Talwar had been called the sole suspect but lack of adequate evidence was also cited.
