Rome, September 5 - The judiciary's self-governing body, the CSM, opened an investigation Thursday into the case of Judge Antonio Esposito and reports of his remarks concerning ex-premier Silvio Berlusconi. A senior committee of the CSM is reviewing the case of the supreme court judge who gave a media interview shortly after the court upheld Berlusconi's conviction for tax fraud. That decision to uphold Berlusconi's conviction has triggered a major political crisis that threatens to bring down the fragile national coalition government. The magistrate has said parts of his interview with the daily Il Mattino had been manipulated to make it appear that he was commenting on the Berlusconi case, when, the judge maintained, he was speaking only in general terms. Il Mattino has said that what it published was a faithful transcription of the interview.
