The pandemic caused by the spread of the SARS-CoV-2 virus has forced the legislators to change the procedures enabling administrative procedures to be improved when access to the authority is restricted. The institution for the serving of documents has been significantly restricted, and therefore it has been made possible for a party or another participant in administrative proceedings to be served with a printout of documents obtained from a communication and information system. This enables the principle of active participation by the parties in administrative proceedings to be implemented, and also postpones the prospect of extending the proceedings. Therefore, it allows further proceedings to be conducted without the need to comply with the rules on the serving of documents in the absence of a threat to health security. Such a solution makes it possible to conduct the proceedings in a way which inspires the confidence of its participants in the public authorities.
