There is a law being discussed in the Italian parliament which intends to set the rules for online publications, and define their responsibilities.
The goal is to recognize and treat professional online news sites in the same way as traditional newspapers, where there is an editor ultimately responsible and accountable for the information
published. This is not unlike press laws in most western countries: if, for instance, the New York Times publishes unfounded corruption allegations against a politician, its editor is ultimately responsible for those allegations, and the politician could sue him for defamation.
There was some initial concern in the blogging world that this law could also apply to bloggers, but this concern was already cleared by the undersecretary to the Cabinet, Ricardo Franco Levi, which is the main curator of the text of the proposed law. He clearly stated that the new law would only apply to professional journalists, and that it would absolutely not apply to bloggers of any kind.
