The Supreme Court on Friday will hear a petition filed by Nupur Talwar and Rajesh Talwar who face trial in the twin murder case of their daughter and domestic help Hemraj.

Nupur and Rajesh, who are both dentists by profession, are CBI's prime suspects in the Aarushi Talwar murder case and were earlier directed by the apex to face trials.

However, weary of facing trials, the dentist couple moved the Supreme Court against its order, seeking a review.

Since the beginning of the probe, the CBI, investigating into the double murder case, has maintained that the parents had a hand in the murders.

On Wednesday, the CBI sleuths strongly opposed the review petition by the Talwars. Referring to Nupur's plea in the Supreme Court, the CBI alleged that she was "misusing" the law by filing several petitions in various courts, hindering the process of investigation.

Friday's Supreme Court observation will have a major impact on Nupur Talwar, who faces arrest for skipping a court hearing.

On April 18, a CBI court trying the Aarushi case issued a non-bailable arrest warrant against Nupur as she did not show up for the hearing. However, the CBI could not take her into custody as she disappeared without a trace when the officials raided her residences in Ghaziabad and New Delhi.

After giving the slip to the CBI officials, Nupur moved the Supreme Court against the non-bailable warrant as well.

Following which, the CBI was directed to refrain from arresting Nupur until a SC bench could hear her plea seeking an anticipatory bail and stay on non-bailable warrant.

Aarushi, 14, was found dead in her bedroom at her residence in Noida, Uttar Pradesh, with her throat slit. Hours later, another dead body was found on the terrace, which was identified as that of the domestic help Hemraj.

The double murder case was handed over to the CBI who suspect that the parents of the girl are main perpetrators of the crime.
