Public Utilities Commission Activities in California

The present commission was established by constitutional amendment in 1911, and additional powers including the regulation of water companies were conferred upon it by legislation that became effective the following year. A supplementary statute, the Act for Regulation of Water Companies, went into effect in 1913. Other acts have since broadened and clarified the commission's authority. The various regulatory statutes were codified, without substantive change, as part of the Public Utilities Code in 1951. The commission is both a court of record and an administrative tribunal
