John also said they will be filing a one-page application to get the closure report so that it can be examined.
When reporters asked whether they will be filing a defamation case against the Central Bureau of Investigation (CBI), she said: "It is too early, let us first examine the report and after that we will decide what to do."
Meanwhile, Aarushi's mother Nupur Talwar said: "The report is a bundle of false allegations, the CBI has condemned us for life and let the killers of my daughter go free."
Rajesh Talwar termed the CBI's allegations sad and claimed that he has cooperated with the agency in its probe.
"What else should I do to prove my innocence," he asked.
Fourteen-year-old Aarushi was found murdered under mysterious circumstances in her parents' Jalvayu Vihar apartment in Noida, Delhi's suburban town in Uttar Pradesh, May 16, 2008.
The family's domestic help, Hemraj, was also found killed on the flat's terrace a day later.
The CBI on Wednesday moved a Ghaziabad court seeking its permission to close the Aarushi murder as an unsolved case on grounds of lack of conclusive evidence.
