The author presents legal frameworks for the construction sector in an area encompassed by nature protection, a national park. Such construction is strictly limited, however possible after reaching the conditions described in the Polish Nature Protection Act. The author conducted research from the perspective of interpretation of the administrative courts' jurisprudence, legal literature as well as papers by non-legal experts on national parks. The main subject of this research was an analysis of the provisions of the Polish Nature Protection Act concerning the conditions allowing for building constructions in the national parks’ area and relations between a protection scheme and other planning documents. The author focuses solely on Polish legislation, particularly the Nature Protection Act and the Construction Law, Environmental Law, and ordinances appropriate for that subject. He points out the relative flexibility of the construction’s prohibition, which often causes arising of undesirable construction projects and which is criticized by many entourages connected with nature protection. The author provides a report on this subject. It presents the attitudes of judges and comentators, addressing the issues associated with exceptions to construction prohibition and complementing those issues with an impact on the protection of national parks schemes.
