Extract (example) : « the PB is not appropriately placed to establish a digital certificate authority and reiterating the importance of technology neutrality and maintaining flexibility for all Contracting Parties, the SC recognised the good practice of using digital certificates with high standards, that are well-recognised and frequently used, and invited Contracting Parties to inform the PB about the certificate technology used to issue e-Apostilles. […] The SC recalled the fundamental principle that, irrespective of format, an Apostille validly issued by one Contracting Party in accordance with the Convention must be accepted by all other Contracting Parties for which the Convention is in force. In this spirit, it encouraged Contracting Parties to take active steps to ensure the acceptance of incoming e-Apostilles ».
