Regions are independent local governments, which means they are not ruled by the central state, but by an assembly elected by the given region. This was supposed to enable citizens to gain better control of their region and influence what is happening in their local area. The region promotes general development in its region and tends to the needs of its citizenship. By fulfilling its tasks, it also protects the public interest defined by law and other regulations.
Elections to the Regional Assemblies are called by the Czech President, and the Assembly’s term of office is four years (see Act No. 130/2000 Coll., on Regional Elections).
The region as an institution has a very similar structure to cities or municipalities. The supreme executive body is the Regional Assembly. Members of the Assembly elect a President of the Region from their ranks – the main official who represents the region and is entitled to act on its behalf. The president’s position in the region corresponds approximately to the position of a mayor of a city or municipality. The Assembly furthermore elects a Regional Council (corresponding to the function of a city or municipal council) which prepares documents for Assembly rulings or issues decisions itself in partial matters. The Regional Authority performs independent and delegated regional functions (see Act No. 129/2000 Coll., on Regions).
A new Pilsen Region Assembly was elected in the regional assembly elections held 12 - 13 October 2012.
