The way in which the Republic of Croatia founds the legitimacy of judiciary duties and thereby enhances the rule of law is analyzed in this paper. It is aimed in particular at the legitimacy of administrative judges upon resolving administrative disputes and passing judgements. To this aim, the independence of administrative judges is considered as well as the mechanisms to which the independence of judicial powers contribute. Then, the way judges are appointed is analyzed, which results in whether citizens can trust the judges’ expertise and moral values. Also analyzed is the mechanism for establishing the expertise of judges through evaluating judges' implementation of duties. Finally, the legitimacy of administrative judges' decisions is also considered through the composition of the court in first instance administrative judicial decisions and through the trust given by citizens in the resolution of administrative disputes according to the individual judge. How administrative court judges in the Republic of Croatia are appointed and assessed in the same way as judges of other regular or specialized courts and how the question of independent implementation of judicial duties correlates regardless of the court wherein the judge is appointed for judicial duty make up a large part of the conclusions related to all judges in the Republic of Croatia. This paper therefore in some way exceeds the very problem area of rule of law and administrative judge legitimacy. U radu se analizira na koji način Republika Hrvatska uspostavlja legitimnost sudačke dužnosti i tako jača vladavinu prava. Rad je posebno usmjeren na legitimnost upravnih sudaca pri rješavanju upravnih sporova i izricanju upravne pravde. U tu svrhu posebno se razmatra neovisnost upravnih sudaca te mehanizmi koji doprinose neovisnosti sudbene vlasti uopće. Zatim se analizira način imenovanja sudaca, slijedom čega se zaključuje mogu li građani imati povjerenje u njihovu stručnost i moralne vrijednosti. Analizira se i mehanizam utvrđivanja stručnosti rada sudaca, kroz vrednovanje obavljanja sudačke dužnost. Konačno, legitimnost upravnosudskih odluka razmatra se i kroz sastav suda u prvostupanjskom upravnosudskom odlučivanju te kroz vjeru koju građanima daje rješavanje upravnih sporova po sucu pojedincu. Kako se suci upravnih sudova u Republici Hrvatskoj imenuju i ocjenjuju na isti način kao i suci drugih redovitih ili specijaliziranih sudova te kako pitanje neovisnosti obavljanja sudačke dužnosti korelira bez obzira na sud u kojem je sudac izabran na sudačku dužnost, velik dio zaključaka odnosi se na sve suce u Republici Hrvatskoj, čime ovaj rad na neki način nadilazi samu problematiku vladavine prava i legitimnosti upravnih sudaca.
