Article 25 Nothing shall prevent the acceptance of an instrument, document or transaction as evidence on the grounds that it is in the form of data message, albeit not in its original form if it is the only evidence that the person asserts. Article 26 When assessing the evidential weight of information, instrument or a document in the form of a data message, regard shall be given to the following: 1. the processes and circumstances under which the data message was generated, stored or communicated; 2. the processes and circumstances under which the integrity of the instrument, document or information contained in the data message was maintained; 3. the processes and circumstances under which the originator of the data message was identified; and 4. any other relevant process or circumstances. Article 27 A contract formed by the interaction of an automated message system and a natural person, or by the interaction of automated message systems, shall not be denied validity or enforceability on the sole ground that no natural person reviewed or intervened in each of the individual actions carried out by the automated message systems or the resulting contract.

The Supreme Council shall issue decisions to determine which electronic signature processes and technologies satisfy the provisions of the preceding provisions. Article 29 Where initiating an electronic signature, the signatory shall comply with the following: 1. exercise reasonable diligence to avoid unauthorised use of its signature creation information. 2. without undue delay, utilise means made available by the certification service provider pursuant to Articles 36 and 37 of this Law to notify any person that may reasonably be expected by the signatory to rely on the electronic signature or to take the necessary measures in support of the electronic signature if the signature creation information has been compromised, or circumstances give rise to a substantial risk that the signature creation information may have been compromised. 3. where a certification certificate is used to support the electronic signature, exercise reasonable diligence to ensure the accuracy and completeness of all material representations made by the signatory that are relevant to the certification certificate throughout its life cycle or that are to be included in the certification certificate.
