Cal. Pub. Util. Code § 5950
The commission shall not permit a telephone corporation that is providing video service directly or through its affiliates pursuant to a state-issued franchise as an incumbent local exchange carrier to increase rates for residential, primary line, basic telephone service above the rate as of July 1, 2006, until January 1, 2009, unless that telephone corporation is regulated under rate of return regulation. However, the commission may allow rate increases to reflect increases in inflation as shown in the Consumer Price Index published by the Bureau of Labor Statistics. This section does not affect the authority of the commission to authorize an increase in rates for basic telephone service that is bundled with other services and priced as a bundle. Nothing in this section is intended to prohibit implementation of commission decision D. 06-04-071 to the extent it has not been implemented prior to July 1, 2006.
