An electronic document can serve as the same purpose as a traditional document. In order to consolidate the information, there are using different media and different recording information. Implementation of the standards, which are contain in Directives, deal with the Law of Electronic Signatures. Article 8 u.p.e. is an example of two-level approach to the problem of electronic signature. It would be interpreted as the electronic data which are signed with usual (“dangerous”) electronic signature cannot refuse a limine evidence in court proceedings and the probative value of the material. However, this will not automatically mean that it is a proof of the document. In civil proceedings, there is also the possibility of using the court’s electronic data unsigned safe (advanced) electronic signature, as the evidence. The ordinary courts have already used the opportunities that Art. 233 § 1, art. 308 and Art. 309 poses.
