The printing of a web page has the probative value that the civil code in art. 2712 c.c. reconnects to mechanical reproductions, arranging that they themselves fully testify the facts and things represented if the one against whom they are produced does not disregard their conformity to the facts or to the things themselves. The problem therefore arises in the event of a disregard.
La Cass. Civ. (Section work, 16-02-2004, No. 2912) thus states: "The reference to the principles relating to the production in court of pre-established documents in relation to a web page, filed during the adjudication proceedings, is not correct because the information obtained from a data transmission network are by their nature "volatile" and susceptible to "continuous transformation" and, regardless of the rituality of their production, the quality of the document must be excluded in a paper copy that is not collected with guarantees of compliance with the original and reference to a well-identified document ".
There are, however, some judgments of merit that give relief - for probative purposes - also to external elements, which can corroborate the authenticity of the print produced.
In the criminal field, see also Cass. pen. Sec. V, 16-07-2010, n. 35511: "The printed page, allegedly" extracted "from the web, can not be considered admissible as a means of proof, because it is a document of uncertain paternity".
In any case, the web page can be considered as an IT document as an "informatic representation of documents, facts or legally relevant data", contained in art. 1 lett. p) of Legislative Decree 82/2005 - Code of Digital Administration and, as such, can be duplicated in digital format.
