The Limitation of the Right to Public Information in the Rulings of Administrative Courts: Selected IssuesIn modern democracies, the right to public information is the basis of functioning of states and international organisations. In Poland, the right to information, as introduced in the Constitution of the Republic of Poland and regulated in the Act on Access to Public Information, provides citizens with extensive possibilities of controlling the state’s transparency. In the Act, access to public information is dened very broadly and covers almost everything that is related to the activity of public authorities. However, this right cannot be of absolute nature. For various reasons, access to public information must be limited. However, such limitations should be exceptions and cannot violate the essence of the right of access to public information, as referred to in the Constitution and the Act on Access to Public Information.In recent years, there has been adramatic increase in the number of requests for public information and public institutions issue decisions to refuse to provide such information. These decisions are then examined by administrative courts. In such cases, administrative courts play avery important role as in their rulings they dene the fundamental concepts included in the Act on Access to Public Information and specify the scope of public information subject to disclosure.The article contains adetailed analysis of abody of rulings of administrative courts concerning the limitation of the right to public information due to personal data protection, business secrets and the value of processed information, which is related to an additional requirement of the applicant acting in public interest. It must be added that rulings on providing access to public information are inconsistent and changeable, which makes it substantially more dicult for public administration authorities to carry out this constitutional right.
