In case urgent retention/preservation of data stored in a computer system or on a data carrier is requested, the request will be executed by the police with a previous consent of the competent judicial authority, i.e. public prosecutor in pre-trial proceedings or court in trial proceedings. The retention period is from 60 – 90 days, it can be extended by another 90 days on the basis of a new request. Before this retention period expires, the requesting state must deliver an MLA request / EIO requesting the seizure of such retained data, otherwise the data will be released upon lapse of the retention period.
In essence, the procedure for producing electronic evidence is subject to the same rules as tangible evidence, i.e. any item that may serve as evidence in criminal proceedings must be surrendered upon request to the court, public prosecutor or the police, this procedure applies both in pre-trial proceeding, as well as in trial. If the evidence is not surrendered voluntarily, the presiding judge (in trial) or public prosecutor (in pre-trial proceedings) can order its seizure (i.e. removal from possession of its holder by the police). The obligation to produce evidence does not apply to documents which contain information with respect to which producing a testimony is not possible (i.e. classified information or information covered by an obligation of secrecy) unless the person in possession of such document was relieved of the obligation of secrecy.
