One of the principles provided by the Polish Code of Administrative Procedure is that of fostering citizens’ confidence in public authorities. It is a declarative principle which derives from the constitutional principle of the democratic rule of law. It functions in the jurisprudence of the Constitutional Tribunal. This principle is a source of two directives for the administrative authorities’ officials: firstly, an official should be competent and kind with a petitioner, and secondly, under the same (or similar) facts of case and legal environment, similar decisions should be adopted. Otherwise people will lose their reliance on administrative bodies. This principle is best manifested in administrative proceedings regarding foreigners or refugees.
