Nanavati has prepared a 14-page report with ten pages of annexures. After BCCI President Sharad Pawar studies the report, the committee will then decide on the quantum of punishment to be given to the person found guilty.
"I was under tension while making the report not because of the subject, but because the issue that I was investigating was very sensitive. So many eyes were on me. I can't afford to make any mistakes", Nanavati told reporters.
"I was very cautious while drafting the report. I have written each and every word carefully and I can justify every sentence in the report," said the Ahmedabad-based lawyer.
Nanavati had said he was satisfied with the answers given by both the players and did not feel the need to question anybody else.
