A bench headed by Justice Ranjan Gogoi, while agreeing to hear the central probe agency's plea against the dentist couple's acquittal, sought a response from them.

It tagged the Central Bureau of Investigation plea with the petititon of Hemraj's wife who also challenged the acquittal.

The CBI had approached the Supreme Court on October 12, 2017, against the Allahabad High Court order of acquittal.

The high court had acquitted the couple by giving them the benefit of doubt.

Aarushi, 14, and Hemraj, were found murdered at their Jal Vayu Vihar home in Noida on May 16, 2008.

The high court's order came on an appeal by the Talwars against a Ghaziabad CBI court judgement that handed them life imprisonment on November 26, 2013.

After Aarushi was found murdered in her bedroom, Hemraj was initially considered a suspect. However, his body too, was discovered a day later in a pool of blood on the terrace of the house.

The high court, while acquitting the Talwar couple, had made comments on the CBI trial court presiding officer, saying he had adopted a "partial and parochial approach" in his 2013 judgment to convict the parents for the double murder.

The court had said that the trial court's judgment was based on the "creation of fanciful reasoning" and "presuming facts with indomitable obstinacy and taking things for granted, and thus basing the conclusion on unfounded evidence".

The Uttar Pradesh Police had accused Rajesh Talwar of killing his daughter in a fit of rage. Rajesh Talwar was arrested on May 23, 2008.

On May 31, 2008, the CBI tookover the case and initially absolved the parents but later held them responsible for the two murders.

On June 13, 2008, Rajesh Talwar's compounder Krishna was arrested by the CBI. Ten days later, Raj Kumar, a servant of a doctor friend of the Talwars, and Vijay Mandal, the domestic help of the Talwars' neighbour, were also arrested.

The three were later freed after no evidence was found against them.
