Jammu Kashmir Liberation Front (JKLF) chief Yasin Malik, one of the accused in the case, appeared before the court from Delhi's Tihar Jail via video conference. 

He once again insisted on his physical appearance while turning down the court's offer of legal aid or amicus, standing counsel for the CBI Monika Kohli said. 

On July 15, Rubaiya had identified Malik and three others as the ones who took her captive. 

Rubaiya was abducted near Lal Ded Hospital on December 8, 1989, when her father was the Union home minister and freed from captivity five days later on December 13 after the then V P Singh government, supported by the BJP at the Centre, released five terrorists in exchange. 

Rubaiya, who stays in Tamil Nadu, is listed as a prosecution witness by the CBI, which took over investigation into the case in early 1990. 

"Rubaiya had to appear before the court for cross-examination (on Tuesday) but she remained absent. The court has issued a bailable warrant against her to appear before the court on the next date of hearing on September 21," the CBI counsel said. 

Kohli said Malik once again pressed for physical appearance so that he could cross-question the witnesses in the case even as the court offered him legal aid or amicus which he declined to accept. 

Malik, 56, is at present lodged in the high-security Tihar Jail after he was sentenced by a special NIA court in Delhi in May. He was arrested in early 2019 in connection with the 2017 terror-funding case registered by the National Investigation Agency (NIA). 

In the last hearing of the case, Rubaiya appeared in the court for the first time and identified Malik, who was present through video conference.
