Supreme Court has rapped CBI for delay in examining vital witnesses in the multi-crore rupee National Rural Health Mission (NRHM) scam cases, in which former Uttar Pradesh cabinet minister Babu Singh Kushwaha is one of the accused, and asked it to complete the job within three months.<br/><br/>The apex court was also critical of the probe agency for not being able to examine key witnesses in the four NRHM cases so far and made it clear that the accused may be granted bail by the trial court if CBI defaulted in examining witnesses.<br/><br/>The bench, comprising Justices TS Thakur and PC Pant, asked the CBI to produce the key witnesses before the trial court for recording of statements and said that pendency of applications filed by some of the accused seeking alteration of charges will not come in the way of trial. <br/><br/>The apex court, which further asked the accused including Kushwaha not to delay the trial court proceedings, also directed the CBI not to add many witnesses as vital in the list of persons to be examined by it.
