Kumar was making submissions with regard to affidavits and statement of key witness and complainant Jagdish Kaur recorded by various commissions, set up to inquire in the incidents of riots.
District Judge J R Aryan was told by Congress leader's counsel I U Khan that the accused has a right to cross-examine the witnesses with regard to evidence available on record.
The counsel questioned the CBI's vacillating stand on using Kaur's two affidavits and statement to Ranganath Mishra Commission and G T Nanavati Commission in prosecuting the case.
In his application, Kumar had said the CBI had earlier brought on record and even examined Kaur's affidavit and statement to the judicial commissions, but it now says that it is not relying on them.
Sajjan Kumar had added that prosecutor R S Cheema had on July 12, 2010 made a statement to the court that affidavits of the witness in the case cannot be used due to contradictions.
Advocate Anil Sharma, appearing for other co-accused, argued that they cannot use the affidavits and statement of Kaur of their own, but as the documents were brought by CBI and the complainant in the court to prosecute them, it gives them the right to use them.
