"This report (submitted by JPC chief P.C. Chacko) is flawed...This report is a bundle of contradictions, untruths and half truths," Sinha told reporters after submitting a dissenting report by the six Bharatiya Janata Party members of the JPC.
He ridiculed the manner in which Chacko moved the report for adoption by the JPC without considering it para by para, as mandated under the parliamentary rules.
Sinha said the BJP members submitted their dissenting report to the JPC secretariat in the afternoon, well before the 5 p.m. deadlines set by the JPC chairman.
This report is a bundle of contradictions, untruths and half truths, Sinha said.
He said a copy of their dissent report had also been submitted to the office of the Lok Sabha speaker.
Sinha admitted that bringing the report before the media even before it was table in Parliament was in a breach of the parliamentary rules and procedures.
"This is contrary to the convention of parliament and should not be made public but the same has been overlooked by Chacko," he said, releasing the dissent note to the JPC report.
