The specific quality of the law applied in administration is its power of authority. No specialist in administrative law has a problem with it, however lawyers representing other branches of law have some ungrounded doubts regarding the structure of administrative law. It should be emphasized that the quality of the administration’s operation is not determined by possible inspections or by compliance with the law. Above all, it depends on the officers themselves, their awareness and responsibility for carrying out public tasks. Before they start their work, officers should know the catalogue of ethical rules related to the performance of tasks and duties of an institution or the office. Law-making by its nature is a long-lasting process and should proceed slowly, as it is impossible to create effective legal norms in a short time only because a given sphere is not sufficiently regulated. The legislative process in our Polish parliament is extremely fast-paced as a result of which the law is imperfect. On the one hand, administrative law is weak because there is no code of material and systemic law, on the other hand, the strength of the legal system lies in its character, i.e. its power of authority.
