In the investigative procedure, the aim is to establish the relevant facts for the procedure and to give the parties the opportunity to express their views (right to be heard). If the authority considers the matter ripe for decision, it may declare the investigative procedure closed.
A crucial part of the investigative procedure is the evidentiary procedure, in which the basis for the decision of the administrative authority is prepared by the authority gaining knowledge of how the relevant facts unfolded. The most important evidence includes the questioning of witnesses, the examination of the parties, documents, experts, and inspection. However, any other evidence suitable for establishing the facts is also admissible.
