Defence counsel Manoj Shishodia said he submitted an application before Central Bureau of Investigation (CBI) Special Judge S. Lal to summon 13 people, including Arun Kumar, for testimony.
The court reserved the order on the application for Friday.
"Of the 13 witnesses we want in the box, 12 are from the original list of 141 witnesses given by the CBI. One additional witness whose name we have added is former joint CBI director Arun Kumar, who claimed Aarushi's parents were innocent," Shishodia said.
The CBI opposed the defence application.
Aarushi, 14, was found murdered at her parents' Noida residence May 16, 2008. The body of the family's domestic help Hemraj, first suspected for Aarushi's killing, was found the next day on the terrace of the house.
