Obtaining evidence from open sources confirms the technological development of activities undertaken by public administration bodies but at the same time it is a response to the actual transfer of people’s activity to the Internet. Undoubtedly, the use of the potential of evidence from open sources in conducted administrative proceedings may contribute to saving time and resources necessary for the proceedings, but also gives the opportunity to obtain knowledge about significant, new circumstances that may affect the decision of the authority. As part of the administration practice, the greatest challenge seems to be to determine the legal admissibility of taking such evidence, especially in the context of ensuring that the parties to the proceedings exercise their rights, especially the right to actively participate in the proceedings. The provisions of the Code of Administrative Procedure currently provide the optimal basis for this evidence.
