A side issue arising from the Peppermint affaire is the relationship between criminal and civil trials rule of evidence.
In a criminal investigation, access to ISP owned traffic data and log files is possible only with a public prosecutor search and seize warrant. One seized, these information are strictly confidential and cannot disclosed – even to the defense counsel – before the trial starts.
The very same data – as the Peppermint affaire shows – can indeed be obtained by a private entity alleging a civivl – not criminal, then – copyright infringement, just asking the civil court to force an ISP to disclose information.
This is a paradox of the Italian legal system, since criminal action is supposed to be the only reason to allow the breach of constitutional rights, while the a civil case only gives the court limited powers. This common-sense rule has been subverted when talking about copyright. Is it fair or acceptable?
