Earlier on July 19, the Delhi High Court heard Kumar's plea seeking cancellation of the anticipatory bail granted by the trial court related to killing of three Sikhs in West Delhi area during the 1984 anti-Sikh riots.
Earlier in April, the court had reopened five cases in connection with the 1984 anti-Sikh riots that were closed in 1986.
The Central Bureau of Investigation (CBI) had also filed appeals against the acquittal of Kumar and life sentence to ex-councilor Balwan Khokhar.
The high court had taken suo motu cognizance as during course of the arguments, Kumar's lawyers mentioned these matters as precedents since co-accused Mahender Yadav, Balwan Khokhar and Kishan Khokhar had been acquitted in them.
The court noted that eyewitnesses had not been examined in those cases and there was a "travesty" since investigation was not done properly.
The court took suo motu cognizance of the "errors" in the 1986 trial judgment, adding that key eyewitnesses were not examined and cases were closed "very rapidly" seemingly without proper investigation and trial.
The bench passed this order after taking note of the trial court judgments passed in 1986 in the five cases.
The apex court had also directed the Centre to deposit more than 190 files in connection with this case.
Attorney General Mukul Rohatgi told the Supreme Court that the SIT in as many as 263 cases had no case files and there was no trace of any victim or witness.
On February 20, the Centre filed a status report in the top court on the investigation conducted by the SIT into anti-Sikh riots cases. The anti-Sikh riots that broke out after the assassination of then prime minister Indira Gandhi, claimed 2,433 lives in Delhi alone. (ANI)
