<P> Cities in Pennsylvania are divided into four classes: Class 1, Class 2, Class 2A, and Class 3 . Class 3 cities, which are the smallest, have either a mayor - council system or a council - manager system like that of a borough, although the mayor or city manager has more oversight and duties compared to their borough counterparts . Pittsburgh and Scranton are the state's only Class 2 and Class 2A cities respectively, and have mayors with some veto power, but are otherwise still governed mostly by their city councils . </P> <P> Philadelphia is the Commonwealth's only Class 1 city . It has a government similar to that of the Commonwealth itself, with a mayor with strong appointment and veto powers and a 17 - member city council that has both law - making and confirmation powers . Certain types of legislation that can be passed by the city government require state legislation before coming into force . Unlike the other cities in Pennsylvania, the Philadelphia city government also has oversight of county government, and as such controls the budget for the district attorney, sheriff, and other county offices that have been retained from the county's one - time separate existence; these offices are elected for separately than those for the city government proper . </P> <P> Texas has 254 counties, the most of any state . </P> <P> Each county is governed by a five - member Commissioners Court, which consists of a county judge (elected at - large) and four commissioners (elected from single - member precincts). The county judge has no veto authority over the decisions of the court; s / he has one vote along with the other commissioners . In smaller counties, the county judge also performs judicial functions, while in larger counties his / her role is limited to the court . Elections are held on a partisan basis . </P>
