The provision of information, refusal to provide access, determination of conditions as to the behaviour occurring within the framework of proceedings regulated by the Act of 25 February 2016 on the re-use of public sector information shall take the forms which are commonly used within the framework of public administration activities. In this case, these are factual actions, contracts, and administrative decisions doctrinally defined as legal forms of action and used by entities obliged to provide information when the entity executes its interest in providing information by way of an application, as well as regardless of the behaviour of the entitled party ex officio (without an application). The present study is devoted to the discussion of these categories of activity, recalling their properties and importance in the process of making information available for re-use.
