Dear experts
My case is placed on Argument oin Charge before the CBI Court. The CBI have produced CDs and Transcripts. MY QUES5ION IS UNDER WHAT CRIMINAL PROCEDURE CODE THE VOICE RECORDINGS CDs can be challenged?
Our case is like this There are FOUR ACCUSED IN THE CHARGESHEET. Three of the accused were arrested and the CBI had added one more accused in the charesheet. Since the CBI has not taken any sample voice ecordings of the Fourth and newly named accused the veracity of the CDs are questionable. Secondly the CBI has not traqnslated the entire voice recordings only a part of it has been tranlated and produced in the transcript.
1. Veracity of the CDS since the newly accused voice has not been identified.since he was the person who demanded and orchesrated the bribe
2. lot of portions in the cds and transcription are missing
if the exoerts can tell me under what section the veracity of the cds can be challenged in court. since the judge has pointed out that under which section
