In this article, the Polish institution of administrative entry to the area in order to carry out repair, maintenance or removal of failures of transmission equipment will be presented. It entitles to public-law interference in the constitutionally protected property right, under the condition that the determinants of its application have been met. The aim of the analysis is to indicate that the expropriation nature of this regulation, which is a specific form of expropriation, requires a strict interpretation of the premises leading to the restriction of the ownership for purposes related to transmission activity. An attempt will be made to demonstrate that the restriction of the ownership made on the basis of an administrative decision meets the expropriation standards applicable in the Polish legal system. The presented issues are not only of purely theoretical importance, but will also be used in the application of legal regulations by both public administration authorities and transmission companies applying for a permission.
