The German term Bezirk (plural Bezirke, derived from circulus, "circle") translated as "district" can refer to the following types of administrative divisions: Stadtbezirk, a subdivision of a city in the sense of a borough (e.g. in Berlin, Hamburg or Vienna), often again subdivided into several quarters and neighbourhoods. According to German Gemeindeordnung codes, the city council resolves upon the implementation by municipal by-law (Satzung). In some cities the Bezirke have limited powers delegated to them by the city's local government, including an assembly resulting from local elections and an own 'mayor' (Bürgermeister). In the German states of Hesse and Rhineland-Palatinate any municipality is authorized to implement Ortsbezirke with own advisory councils and local administrators. The state law in North Rhine-Westphalia commits the municipal administration of an independent city to subdivide the urban area into Stadtbezirke. In Austria, the word Bezirk is used with different meanings in three different contexts: Some of the tasks of the administrative branch of the national and regional governments are fulfilled by the 95 district captaincies (Bezirkshauptmannschaften, also translated as district administrative office). The area a district administrative office is responsible for is often, although informally, called a district (Bezirk). A number of statutory cities, currently 15, are not served by any district administrative office. Their respective municipal bureaucracies handle the tasks normally performed by the district administrative office. The cities of Vienna and Graz are divided into municipal districts (Stadtbezirke), assisting the respective municipal governments. From the point of view of the judiciary of Austria, the country is subdivided into 115 judicial districts (Gerichtsbezirke), each corresponding to one of the country's 115 lowest-level trial courts. The Italian autonomous provinces of Trentino and South Tyrol, are divided into Bezirksgemeinschaften (comunità comprensoriali).
