In a counter affidavit filed before District Judge J R Aryan, Kumar said the prosecution cannot withhold documents as the court has to see whether sanction granted by government to prosecute the accused was valid or not.
Kumar's affidavit claimed the statement of prosecution witness Vishwendra Singh, the then deputy secretary (Home) of city government and now private secretary of the Lieutenant Governor of Delhi, was misleading that "he had proved the order of sanction dated January 1, 2010 issued by the order of Lieutenant Governor of Delhi."
"It is a sort of mini-trial to arrive at just decision. Thus, there is nothing in public interest not to disclose the same. Had it been so, he could never bring it to depose before the court," the affidavit filed through advocate Anil Sharma said.
The court asked the CBI to file its response, if any, and fixed February 12 for orders on the issue of granting privilege to the witness for not producing the complete file.
Sanction for prosecution of accused charged under section 153A (causing disharmony between different communities) is mandatory.
