This article is an attempt to comprehensively describe the rules and regulations that should be followed by officers and employees of Polish secret services when they need to provide classified information. It also describes the substantive and formal aspects of making such information available by government administration bodies managing secret services. Presenting the above rules and principles, the article is based mainly on the provisions of the Act on the Internal Security Agency and the Foreign Intelligence Agency, the solutions of which later served as a model for solutions included in the provisions regulating the operation of other secret services of the Republic of Poland. The article also shows the problems and differences in interpretation that occur in statutory provisions, which should be resolved, taking into account the interest of classified information and the goods protected by them. These problems became especially visible after the entry into force of the new act on the protection of classified information, which has been in force since January 1, 2010. It changed a number of acts regulating matters related to the disclosure of classified information, and this in turn made it necessary to look at the consequences of these changes in the functioning of institutions such as special services.
