JUC Šebastián Sutor, who worked in Brno between the years 1647 and 1666 as an urban syndic, compiled a unique office order pertaining to the principles of the administration and managing a registry. In this study, the author analyses these principles and, in the context of the research, other official municipal sources of that time and indicates that only documents of an economic and accounting character were exempted from direct supervision of the city council in the 17th century and were administered through the city accounting office (Buchhalterei). The author also states that Sutor's office order, which has not thus far been subjected to any kind of research activity, is unique testimony to, at that time, the very progressive practices of the Brno syndic. These practices were followed in Brno long before they were observed in other cities and foreshadowed 'bureaucratization' of the 18th century in the sense of the orderly management of documents.
