This proposal, which the Italian Parliament is currently debating, provides, among other things, a requirement to all websites to publish, within 48 hours of the request and without any comment, a correction of any content that the applicant deems detrimental to his/her image.
Unfortunately, the law does not require an evaluation of the claim by an impartial third judge - the opinion of the person allegedly injured is all that is required, in order to impose such correction to any website.
