California Code, Public Utilities Code - PUC § 101001

It appears that public interest and necessity may require that a transit district be established in the territory comprising the City of Bakersfield and the unincorporated area of the County of Kern adjacent to the city in order to meet the public transit problems within such territory. There is no general law under which such a district could be formed and, accordingly, the enactment of a special law providing for the formation of such a special district is required.
