<P> The Municipal Courts are the most active courts, with the County and District Courts handling most other cases and often sharing the same buildings . Administration is the responsibility of the Supreme Court, which is aided by the Texas Office of Court Administration, the Texas Judicial Council and the State Bar of Texas (the Texas Bar). </P> <P> Texas has a total of 254 counties, by far the largest number of counties of any state . </P> <P> Each county is run by a five - member Commissioners' Court consisting of four commissioners elected from single - member districts (called commissioner precincts) and a county judge elected at - large . The county judge does not have authority to veto a decision of the commissioners court; the judge votes along with the commissioners (being the tie - breaker in close calls). In smaller counties, the county judge actually does perform judicial duties, but in larger counties the judge's role is limited to serving on the commissioners court and certifying elections . Certain officials, such as the sheriff and tax collector, are elected separately by the voters, but the commissioners court determines their office budgets, and sets overall county policy . All county elections are partisan . The Commissioners Courts in Texas are served and provided continued education by the County Judges and Commissioners Association events and the official association publication County Progress . </P> <P> Counties in Texas have limited regulatory (ordinance) authority . Counties in Texas do not have zoning power (except for limited instances). However, counties can collect a small portion of property tax and spend it to provide residents with needed services or to employ the power of eminent domain . </P>
