The court termed such questions as "scandalous" and asked the counsel to limit their queries to those that relate to the incident.
"This question (regarding intimate relations of victim and her friend) is disallowed as it is not relevant. You can't harass the witness like this. Question is disallowed being scandalous," Additional Sessions Judge (ASJ) Yogesh Khanna said.
Anand was appearing for accused Mukesh, while Vivek Sharma was for Pawan Gupta.
Pawan, Mukesh and four others, including a juvenile had allegedly gangraped the 23-year-old victim and assaulted her male friend, in a moving bus, on the night of December 16, 2012. The girl died in a Singapore hospital on December 29.
