The counsel representing Rajesh and Nupur Talwar had sought reports of narco, lie-detector and polygraph tests of Rajkumar, Krishna and Vijay Mandal along with Hyderabad-based CDFD lab's worksheet on the case.
They had argued that the reports had not been submitted to the court.
The court of special CBI judge S Lal rejected the plea and fixed December 6 as next date of hearing.
Teenager Aarushi and domestic help Hemraj were murdered in 2008 and her parents, dentists Rajesh and Nupur Talwar, are being tried for the killings.
