Opposite party filed criminal case u/s. 494 & 114 against me and my family members on the basis of hearsay and few public documents. No concrete proof is on record. Now I challenged process order issued against me in revisional court but since last 1 year no hearing was taken. Meanwhile Magistrate court is moving. Can I invoke section 91 Cr.Pc to ask source of information on affidavit. I have been advised that 91 Cr.Pc is only for production of documents and summoned to witness and therefore can't ask source of info. My say is asking source of info on affidavit is also a kind of 'production of document'. Kindly guide me.
