Additional Sessions Judge Kaveri Baweja granted time to the defence counsel to file the response and fixed the case for January 27.
The prosecutor has sought court's permission to file original medical records and potency test report of accused Shyam Lal, who has claimed to be impotent, saying it was untraceable earlier.
The court had pulled up the police for filing documents at a belated stage as it had already reserved the judgment in the case for today, which would now be pronounced later.
All the nine accused were arrested. The six adult accused - Mahendra alias Ganja (26), Mohd Raja (22), Raju (23), Arjun (21), Raju Chakka (22) and Shyam Lal (55) - are in judicial custody and facing trial.
