Congress leader Sajjan Kumar and five others, facing trial in a 1984 anti-Sikh riots case, on Monday concluded their final arguments in a Delhi court, where they questioned the conduct of the complainant and key witness, and accused her of changing her stand often.

Now the prosecution will rebut defence arguments from February 19 to 21.

The Central Bureau of Investigation had commenced final arguments in the case on March 31 last.

Defence counsel claimed that complainant and key witness Jagdish Kaur, who lost five of her family members during the riots, was not a credible witness as her stance kept changing before the Ranganath Mishra Commission and the Nanavati Commission.

The trial court had framed charges against Kumar and the five others under Sections 302 (murder), 395 (dacoity), 427 (mischief to cause damage to property), 153-A (promoting enmity between different communities) and other provisions of the Indian Penal Code after the CBI filed a charge sheet.
