The Central Forensic Science Laboratory (CFSL) has found no doctoring of the recorded conversation in which lawyer-activist Shanti Bhushan is heard discussing with Samajwadi Party (SP) leader Mulayam Singh and his former lieutenant Amar Singh about "managing" the judiciary.Bhushan and his supporters rejected both the CFSL report as well as demands for his resignation as co-chairman of a committee to draft the anti-corruption Lokpal Bill.
A CD containing the conversation was anonymously distributed to newspaper offices soon after Bhushan and his son Shanti Bhushan fought their way into the drafting committee after an agitation led by Gandhian Anna Hazare.
The Bhushans had claimed that two private forensic laboratories they hired had found the recording tampered with.
"The recorded conversation in the CD could not have been tampered (with)," the five-page CFSL report, signed by four experts, including its director, Dr Rajinder Singh, said.
The report has been sent to the Delhi Police, which is investigating the veracity of the CD. The police said the CFSL report was the only valid document for the investigations.
The CFSL report said: "The conversation is in continuity and no abrupt change in speech signal could be detected, is in contextual continuity; no abrupt change in the phase of speech signal could be detected and no change in background noise pattern throughout the recording could be observed."
PC Gandhi of Hyderabad-based Truth Labs, one of the labs used by the Bhushans, told HT that he stood by the report that the conversation was doctored.
He refused to say more till he saw the CFSL report.
Hindustan Times had got the CD analysed at yet another government laboratory, which also gave the same conclusion as CFSL.
The CFSL examination was carried out in a computerised speech laboratory using waveform and spectrographic analysis.
The other government agency that examined the CD for HT had used softwares Sonic Visualiser and DC Live Forensic.
