Lawyer-activist Prashant Bhushan, on Thursday, refused to disclose the identity of the whistleblower who provided him with the visitor's logbook from CBI chief Ranjit Sinha's Delhi residence and other documents, which allegedly revealed his close connections with 2G and coal scam accused.

Bhushan, who is representing NGO CPIL in connection with the case, filed an affidavit claiming that the identity of the whistleblower is not relevant to the case and said that he would take full responsibility for its genuineness.

"I can put my life on stake to prove that the register is genuine. It is impossible to fabricate it. I can guarantee that it is a genuine register which was maintained at the gate. It's clear that prosecution case in 2G scam is being destroyed by the director," IBNLive quoted Bhushan as saying.

However, apex court Bench of Justices HL Dattu and SA Bobde was not convinced with Bhushan's argument and told him that information about the whistleblower is crucial for the court as the claim could potentially harm the person's (Sinha's) reputation and affect the 2G scam case, which is still under trial.

"We want to know about the authenticity of the whistleblower. It can have serious consequences on reputation of persons and also on the (2G) trial court. Give us the source of information. How this information get leaked out is important. We have to satisfy ourselves first," Financial Express cited the Bench's statement.

The next hearing has been scheduled for Monday, 22 September.
